Baltimore Orioles

At the end of the 1900 season, the American League removed itself from baseball's National Agreement (the formal understanding between the NL and the minor leagues). Two months later, the AL declared itself a competing major league. As a result of several franchise shifts, the Brewers were one of only two Western League teams that didn't fold, move or get kicked out of the league (the other being the Detroit Tigers). In its first game in the American League, the team lost to the Detroit Tigers 14–13 after surrendering a nine-run lead in the 9th inning.[11] To this day, it is a major league record for the biggest deficit overcome that late in the game.[12] In the first American League season in 1901, they finished last (eighth place) with a record of 48–89. During its lone Major League season, the team played at Lloyd Street Grounds, between 16th and 18th Streets in Milwaukee.

After one year in Milwaukee, the club relocated to St Louis, and for a while enjoyed some success, especially in the 1920s behind Hall of Fame first baseman George Sisler. However, the team's fortunes declined from then on, as playing success and gate receipts instead went increasingly to the Browns' own tenants at Sportsman's Park, the National League Cardinals, who became perennial NL contenders in the 1920s due to organizational innovations by team president Branch Rickey, a former player and manager for the Browns.

Through World War II, the Browns won only one pennant, in the 1944 season stocked with wartime replacement players, and lost to the Cardinals in the third and last World Series played entirely in one ballpark, (until 2020 due to the COVID-19 pandemic).

In 1953, with the Browns unable to afford even basic stadium upkeep and facing potential condemnation of the park by safety inspectors, owner Bill Veeck sold Sportsman's Park to the Cardinals and attempted to move the club back to Milwaukee, but this was vetoed by the other American League owners.

Instead, Veeck sold his franchise to a partnership of Baltimore businessmen. Because Veeck was unpopular with fellow American League owners, his leaving baseball was a condition for the AL owners to approve the move.[13][14]

The "Oriole Bird", which has been the official mascot figure since April 6, 1979.[15]

The Miles-Krieger (Gunther Brewing Company)-Hoffberger group renamed their new team the Baltimore Orioles soon after taking control of the franchise. The nickname has a rich history in Baltimore, having been used by a National League club in the 1890s, an American League club (1901–02), and an International League club (AAA) from 1903 to 1953. The IL Orioles' most famous player was a local Baltimore product, hard-hitting left-handed pitcher Babe Ruth. When Oriole Park burned down in 1944, the team moved to a temporary home, Municipal Stadium, where they won the Junior World Series. Their large postseason crowds caught the attention of the major leagues, eventually leading to a new MLB franchise in Baltimore.[16]

The new AL Orioles took about six years to become competitive even after jettisoning most of the holdovers from St. Louis. Under the guidance of Paul Richards, who served as both field manager and general manager from 1955 to 1958 (the first man since John McGraw to hold both positions simultaneously),[17] the Orioles began a slow climb to respectability. While they posted a .500 record only once in their first five years (76–76 in 1957), they were a success at the gate. In their first season, for instance, they drew more than 1.06 million fans – more than five times what they had ever drawn in their tenures in Milwaukee and St. Louis. This came amid slight turnover in the ownership group. Miles served as team president for two years, then stepped down in favor of developer James Keelty. In turn, Keelty gave way in 1960 to financier Joe Iglehart.

By the early 1960s, stars such as Brooks Robinson, John "Boog" Powell, and Dave McNally were being developed by a strong farm system. The Orioles first made themselves heard in 1960, when they finished 89–65, good enough for second in the American League. While they were still eight games behind the Yankees, it was the first time they had been a factor in a pennant race that late in the season since 1944. It was also the first season of a 26-year stretch where the team would have only two losing seasons. Shortstop Ron Hansen was named AL Rookie of the Year, and first-year pitcher Chuck Estrada tied for the league lead in wins with 18, finishing second to Hansen in the Rookie of the Year balloting.

After the 1965 season, Hoffberger acquired controlling interest in the Orioles from Iglehart and installed himself as president. He had been serving as a silent partner over the past decade despite being the largest shareholder. Frank Cashen, advertising chief of Hoffberger's brewery, became executive vice-president.

The Orioles farm system had begun to produce a number of high-quality players and coaches who formed the core of winning teams; from 1966 to 1983, the Orioles won three World Series titles (1966, 1970, and 1983), six American League pennants (1966, 1969, 1970, 1971, 1979, and 1983), and five of the first six American League East titles. The first of those titles, in 1966, made the Orioles the last of the eight teams that made up the American League from 1903 to 1960 to win a World Series.

During this time, the Orioles were known for playing baseball the Oriole Way, an organizational ethic best described by longtime farm hand and coach Cal Ripken, Sr.'s phrase "perfect practice makes perfect!" The Oriole Way was a belief that hard work, professionalism, and a strong understanding of fundamentals were the keys to success at the major league level. It was based on the belief that if every coach, at every level, taught the game the same way, the organization could produce "replacement parts" that could be substituted seamlessly into the big league club with little or no adjustment. This led to a run of success from 1966 to 1983 which saw the Orioles become the envy of the league, and the winningest team in baseball.

During this stretch, three different Orioles were named Most Valuable Player (Frank Robinson in 1966, Boog Powell in 1970, and Cal Ripken Jr. in 1983), four Oriole pitchers combined for six Cy Young Awards (Mike Cuellar in 1969, Jim Palmer in 1973, 1975, and 1976, Mike Flanagan in 1979, and Steve Stone in 1980), and three players were named Rookie of the Year (Al Bumbry in 1973, Eddie Murray in 1977, and Cal Ripken Jr. in 1982).

It was also during this time that the Orioles severed their last remaining financial link to their era in St. Louis. In 1979, Hoffberger sold the Orioles to his longtime friend, Washington attorney Edward Bennett Williams. As part of the deal, Williams bought the publicly traded shares Donald Barnes had issued in 1936 while the team was still in St. Louis, making the franchise privately held once again and severing one of the few remaining links with the Orioles' past in St. Louis.

During this rise to prominence, Weaver Ball came into vogue. Named for fiery manager Earl Weaver, it was defined by the Oriole trifecta of "Pitching, Defense, and the Three-Run Home Run." When an Oriole GM was told by a reporter that Weaver, as the skipper of a very talented team, was a "push-button manager", he replied, "Earl built the machine and installed all the buttons!"

As Frank and Brooks Robinson grew older, newer stars emerged, including multiple Cy Young Award winner Jim Palmer and switch-hitting first baseman Eddie Murray. With the decline and eventual departure of two other professional sports teams in the area, the NFL's Baltimore Colts and baseball's Washington Senators, the Orioles' excellence paid off at the gate, as the team cultivated a large and rabid fan base at Memorial Stadium.

After winning the 1983 World Series,[18] the Orioles spent the next five years in steady decline, finishing 1986 in last place for the first time since the franchise moved to Baltimore. The team hit bottom in 1988 when it started the season 0–21, en route to 107 losses and the worst record in the majors that year. The "Why Not?" Orioles surprised the baseball world the following year by spending most of the summer in first place until September when the Toronto Blue Jays overtook them and seized the AL East title on the final weekend of the regular season. The next two years were spent below the .500 mark, highlighted only by Cal Ripken Jr. winning his second AL MVP Award in 1991. The Orioles said goodbye to Memorial Stadium, the team's home for 38 years, at the end of the 1991 campaign.

Opening to much fanfare in 1992, Oriole Park at Camden Yards was an instant success, spawning other retro-designed major league ballparks within the next two decades. The stadium became the site of the 1993 All-Star Game. The Orioles returned to contention in those first two seasons at Camden Yards, only to finish in third place both times.

In 1993, with then-owner Eli Jacobs forced to divest himself of the franchise, Baltimore-based attorney Peter Angelos, along with the ownership syndicate he headed, was awarded the Orioles in bankruptcy court in New York City, returning the team to local ownership for the first time since 1979. The Orioles, who spent all of 1994 chasing the New York Yankees, occupied second place in the new five-team AL East when the players strike, which began on August 11, forced the eventual cancellation of the season.[19]

The numbers on the Orioles' warehouse changed from 2130 to 2131 to celebrate Cal Ripken Jr. passing Lou Gehrig's consecutive games played streak.

The labor impasse would continue into the spring of 1995. Almost all the major league clubs held spring training using replacement players, with the intention of beginning the season with them. The Orioles, whose owner was a labor union lawyer, were the lone dissenters against creating an ersatz team, choosing instead to sit out spring training and possibly the entire season. Had they fielded a substitute team, Cal Ripken Jr.'s consecutive games streak would have been jeopardized. The replacements questions became moot when the strike was finally settled. The Ripken countdown resumed once the season began. Ripken finally broke Lou Gehrig's consecutive games streak of 2,130 games in a nationally televised game against the California Angels on September 6.[20] This was later voted the all-time baseball moment of the 20th century by fans from around the country in 1999. Ripken finished his streak with 2,632 straight games, finally sitting on September 20, 1998, the Orioles final home game of the season against the Yankees at Camden Yards.

Before the 1996 season, Angelos hired Pat Gillick as general manager. Given the green light to spend heavily on established talent, Gillick signed several premium players like B. J. Surhoff, Randy Myers, David Wells and Roberto Alomar. Under new manager Davey Johnson and on the strength of a then-major league record 257 home runs in a single season, the Orioles returned to the playoffs after a 12-year absence by clinching the AL wild card berth. Alomar set off a firestorm in September when he spat into home plate umpire John Hirschbeck's face during an argument in Toronto. He was later suspended for the first five games of the 1997 season, even though most wanted him banned from the postseason. After dethroning the defending American League champion Cleveland Indians 3–1 in the Division Series, the Orioles fell to the Yankees 4–1 in an ALCS notable for right field umpire Rich Garcia's failure to call fan interference in the first game of the series, when 12-year-old Yankee fan Jeffrey Maier reached over the outfield wall to catch an in-play ball, which was scored as a home run for Derek Jeter, tying the game at 4–4 in the eighth inning. Absent Maier's interference, it appeared as if the ball might have been off the wall or caught by right fielder Tony Tarasco. The Yankees went on to win the game in extra innings on an ensuing walk-off home run by Bernie Williams.

The Orioles went "wire-to-wire" (first place from start to finish) in winning the AL East title in 1997. After eliminating the Seattle Mariners 3–1 in the Division Series, the team lost again in the ALCS, this time to the underdog Indians 4–2, with each Oriole loss by only a run. Johnson resigned as manager after the season, largely due to a spat with Angelos concerning Alomar's fine for missing a team function being donated to Johnson's wife's charity.[21] Pitching coach Ray Miller replaced Johnson.

With Miller at the helm, the Orioles found themselves not only out of the playoffs, but also with a losing season. When Gillick's contract expired in 1998, it was not renewed. Angelos brought in Frank Wren to take over as GM. The Orioles added volatile slugger Albert Belle, but the team's woes continued in the 1999 season, with stars like Rafael Palmeiro, Roberto Alomar, and Eric Davis leaving in free agency. After a second straight losing season, Angelos fired both Miller and Wren. He named Syd Thrift the new GM and brought in former Cleveland manager Mike Hargrove. In a rare event on March 28, 1999, the Orioles staged an exhibition series against the Cuban national team in Havana. The Orioles won the game 3–2 in 11 innings. They were the first Major League team to play in Cuba since 1959, when the Los Angeles Dodgers faced the Orioles in an exhibition. The Cuban team visited Baltimore in May 1999 (winning 10–6).

The first decade of the 21st century saw the Orioles struggle due to the combination of lackluster play on the team's part, a string of ineffective management, and the ascent of New York and Boston to the top of the game – each rival having a clear advantage in financial flexibility due to their larger media market size. Further complicating the situation for the Orioles was the relocation of the National League's Montreal Expos franchise to nearby Washington, D.C. in 2004. Orioles owner Peter Angelos demanded compensation from Major League Baseball, as the new Washington Nationals threatened to carve into the Orioles fan base and television dollars. However, there was some hope that having competition in the larger Baltimore-Washington metro market would spur the Orioles to field a better product to compete for fans with the Nationals.

A new President of Baseball of Operations named Andy MacPhail was brought in about halfway through the 2007 season. MacPhail spent the remainder of the 2007 season assessing the talent level of the Orioles, and determined that significant steps needed to be made if the Orioles were ever to be a contender again in the American League East. He completed two blockbuster trades during the next off-season, each sending a premium player away in return for five prospects (or younger less expensive players). Tejada, who had hit .296 with 18 HR and 81 RBI in 2007, went to the Houston Astros in exchange for outfielder Luke Scott, pitchers Matt Albers, Troy Patton, and Dennis Sarfate, and third baseman Mike Costanzo. Also, the newly designated ace of the Orioles rotation Érik Bédard, who went 13–5 with a 3.16 ERA in 2007 with 221 strikeouts, was sent to the Seattle Mariners in exchange for top outfield prospect Adam Jones, left-handed pitcher George Sherrill, and three minor league pitchers Chris Tillman, Kam Mickolio, and Tony Butler. The Bedard trade in particular would go down as one of the most lop-sided and successful trades in the history of the franchise.

The Orioles celebrate a 6–5 victory over the Mariners at Camden Yards on May 13, 2010.

While MacPhail would find success in most of his trades made for the Orioles over the long-term, the veteran stop acquisitions that he would make would not often pan out, and as a result, the team would never finish higher than 4th place in the AL East, or with more than 69 wins, while MacPhail was in charge. Although some of his free agent signings would have positive contributions (such as reliever Koji Uehara), most gave mediocre returns, at best. In particular, the Orioles never managed to cobble together a successful pitching staff during this time. Their most consistent starting pitcher from 2008 to 2011 was the late bloomer Jeremy Guthrie who was named the Opening Day starter in 3 of the 4 seasons and had a cumulative 4.12 ERA during this stretch.

Following Davey Johnson's dismissal after the 1997 playoff season, Orioles ownership struggled to find a manager that they liked, and this time period was no exception. Dave Trembley was brought on as an interim manager in June 2007, and had the interim tag removed later that year. Trembley was at the helm again in 2008 and 2009 but was never able to lead the team out of the cellar in the AL East. After starting the 2010 season a dismal 15–39, Dave Trembley was fired and third base coach Juan Samuel was named the interim manager. The Orioles were seeking a more permanent solution at manager as the 2010 season continued to unfold, and two-time AL Manager of the Year Buck Showalter was eventually hired in July 2010. The Orioles went 34–23 after Buck took over, foreshadowing that a brighter future might be on the horizon, and giving Orioles fans renewed hope and optimism for the team's future.

The Orioles made some aggressive moves to improve the team in 2011 in the hopes of securing their first playoff berth since 1997. Andy MacPhail completed trades to bring in established veterans like Mark Reynolds and J. J. Hardy from the Diamondbacks and Twins, respectively. Veteran free agents Derrek Lee and Vladimir Guerrero were also brought in to help improve the offense. At the 2011 trade deadline, fan favorite Koji Uehara was sent to the Texas Rangers in exchange for Chris Davis and Tommy Hunter, a move that would not pay immediate dividends, but would be crucial to the team's later success. While these moves had varying impacts, the Orioles did score 95 more runs in 2011 than they had the previous year. The team still finished last in the AL East due to the utter failures of the team's pitching staff. Brian Matusz compiled one of the highest single-season ERAs in MLB history (10.69 over 12 starts) and every pitcher who started a game for the Orioles in 2011 ended the season with an ERA of 4.50 or higher except for Jeremy Guthrie. The Orioles finished 30th out of 30 MLB teams that year with a 4.89 team ERA. Andy MacPhail's contract was not renewed in October 2011 and a search for a new GM began. After a public interview process where several candidates declined to take the position, ex-GM Dan Duquette was brought in to serve as the Executive Vice-President of Baseball Operations.

Duquette wasted no time in overhauling the Orioles roster, especially the MLB-worst pitching staff. He traded fan favorite Jeremy Guthrie to the Colorado Rockies in exchange for Jason Hammel. He brought in new free agent starting pitcher Wei-Yin Chen from the Nippon Professional Baseball league, and Miguel González was signed as a minor league free agent. Nate McLouth was signed to a minor league deal in June 2012 and would prove to make a significant impact down the stretch. This year also marked the debut of the much hyped prospect Manny Machado.

Adam Jones in 2017

The Orioles won 93 games in 2012 (after winning 69 in the previous year) thanks in large part to a 29–9 record in one-run games, and a 16–2 record in extra inning games. The difference between this Orioles bullpen and bullpens past was like night and day, led by Jim Johnson and his 51 saves. He finished with a 2.49 ERA that season with Darren O'Day, Luis Ayala, Pedro Strop, and Troy Patton all finishing as well with ERAs under 3.00. Experts were amazed as the team continued to outperform expectations, but regression never came that year. They battled with the New York Yankees for first place in the AL East up until September, and would earn their first playoff berth in 15 years by winning the second wildcard spot in the American League.

In the 'sudden death' wildcard game against the Texas Rangers, Joe Saunders (acquired in August of that year in exchange for Matt Lindstrom) defeated Yu Darvish to help the Orioles advance to the divisional round, where they faced a familiar opponent, the Yankees. The Orioles forced the series to go five games (losing games 1 and 3 of the series, while winning 2 and 4), but CC Sabathia outpitched the Orioles Jason Hammel in Game 5 and the Orioles were eliminated from the playoffs.

While the Orioles would ultimately miss the playoffs in 2013, they finished with a record of 85–77, tying the Yankees for third place in the AL East. By posting winning records in 2012 and 2013, the Orioles achieved the feat of back-to-back winning seasons for the first time since 1996 and 1997.

On September 16, 2014, the Orioles clinched the division for the first time since 1997 with a win against the Toronto Blue Jays as well as making it back to the postseason for the second time in three years. The Orioles finished the 2014 season with a 96–66 record and went on to sweep the Detroit Tigers in the ALDS. The O's were then in turn swept by the Kansas City Royals in the ALCS.

Out of an abundance of caution, the Baltimore Orioles announced the postponement of the April 27 and 28 games in 2015 against the Chicago White Sox following violent riots in West Baltimore following the death of Freddie Gray.[22] Following the announcement of the second postponement, the Orioles also announced that the third game in the series scheduled for Wednesday, April 29 was to be closed to the public and would be televised only,[23] apparently the first time in 145 years of Major League Baseball that a game had no spectators and breaking the previous 131-year-old record for lowest paid attendance to an official game (the previous record being 6.) [24] The Orioles beat the White Sox, 8–2.[25] The Orioles said the make-up games would be played Thursday, May 28, as a double-header. In addition, the weekend games against the Tampa Bay Rays was moved to the Rays' home stadium in St. Petersburg where Baltimore played as the home team.[26][27]

Despite the 2016 season being another above .500 season for the Orioles; they would fail to win their division, but were able to secure a Wild card spot. However, they would lose against the Toronto Blue Jays in the AL Wild Card game. Baltimore has not made the postseason since then. In 2017, the Orioles started with a modest 22–10 record. Despite early season success, the Orioles suffered their first losing season since 2011. The Orioles would suffer one of Major League Baseball's worst seasons in 2018, en route to going 47–115. 2018 proved to be general manager Duquette and Showalter's final season in Baltimore, as their contracts were not renewed after the season.

The Orioles began their rebuild by trading away fan favorites Manny Machado, Zach Britton, Jonathan Schoop, Brad Brach, Kevin Gausman, and Darren O'Day in July 2018. In 2019, the Orioles finished 54–108, which was the second Orioles team to surpass the 1988 Orioles team's losses. In 2020, the Orioles experienced an upside in their ongoing rebuild, as they finished 25–35 in a season shortened by the COVID-19 pandemic, their best finish since 2017. In 2021, the Orioles experienced two different losing streaks of at least 14, en route to a 52–110 finish. 2021 was their third 110-loss season in team history. Their first was 1939 when they were known as the St. Louis Browns, the second was in 2018 as the Baltimore Orioles.

On June 9, 2022, Louis Angelos sued his brother, Orioles chairman and CEO John P. Angelos, and mother Georgia Angelos in Baltimore County Circuit Court.[28][29] Louis Angelos claims that their father intended for the brothers and their mother to share control of the team. The lawsuit states the elder Angelos collapsed in 2017 due to heart problems and established a trust with his wife and sons as co-trustees. Louis Angelos is seeking to have his brother and mother removed as co-trustees of the trust that controls the Orioles and removed as co-agents of Peter Angelos' power of attorney.

The suit claims Georgia Angelos wants to sell the team and an advisor attempted to negotiate a sale in 2020 but John Angelos vetoed a potential deal. The suit claims Angelos unilaterally fired long-time employees loyal to his father, including former center fielder Brady Anderson, the longtime special assistant to the executive vice president for baseball operations. The suit claims John Angelos transferred tens of millions of dollars worth of property out of his father's law firm and into a limited liability company controlled by his personal attorney.[28]

In separate statements released by the team Georgia and John Angelos refuted the claims.[30][31]

In the event of any sale, Major League Baseball has reportedly encouraged Cal Ripken to be part of any incoming ownership group that may take control of the team.[32]

In Baltimore, Orioles radio broadcasts can be heard on WBAL-AM and WIYY, both owned by Hearst Television. Geoff Arnold, Melanie Newman, Brett Hollander, Scott Garceau and Kevin Brown alternate as play-by-play announcers. WBAL feeds the games to a network of 36 stations, covering Washington, D.C. and all or portions of Maryland, Pennsylvania, Delaware, Virginia, West Virginia, and North Carolina.

This is WBAL's fourth stint as the Orioles flagship. WBAL has carried Orioles games for most of the team's time in Baltimore. Prior to WBAL and WIYY, Orioles games were broadcast locally on WJZ-FM from 2015 to 2021. WJZ had earlier carried broadcasts from 2007 to 2010.

Six former Orioles franchise radio announcers have received the Hall of Fame's Ford C. Frick Award for excellence in broadcasting: Chuck Thompson (who was also the voice of the old NFL Baltimore Colts); Jon Miller (now with the San Francisco Giants); Ernie Harwell, Herb Carneal; Bob Murphy and Harry Caray (as a St. Louis Browns announcer in the 1940s[35]).

Other former Baltimore announcers include Josh Lewin (currently with New York Mets), Bill O'Donnell, Tom Marr, Scott Garceau (returned in 2020 season), Mel Proctor, Michael Reghi, former major league catcher Buck Martinez (now Toronto Blue Jays play-by-play), and former Oriole players including Brooks Robinson, pitcher Mike Flanagan and outfielder John Lowenstein. In 1991, the Orioles experimented with longtime TV writer/producer Ken Levine as a play-by-play broadcaster. Levine was best noted for his work on TV shows such as Cheers and M*A*S*H, but lasted only one season in the Orioles broadcast booth.

MASN, co-owned by the Orioles and the Washington Nationals, is the team's exclusive television broadcaster. MASN airs almost the entire slate of regular season games. Some exceptions include Saturday games on either Fox (via its Baltimore affiliate, WBFF) or Fox Sports 1, or Sunday Night Baseball on ESPN. Many MASN telecasts in conflict with Nationals' game telecasts air on an alternate MASN2 feed.

Veteran sportscaster Gary Thorne served as lead television announcer from 2007 to 2019, with Jim Hunter as his backup along with Hall of Fame member and former Orioles pitcher Jim Palmer and former Oriole infielder Mike Bordick as color analysts, who almost always work separately. In 2020, Thorne and Palmer were removed from the television booth due to COVID-19 concerns, and replaced with Scott Garceau. In 2021, MASN let go Thorne, Hunter, analysts Mike Bordick and Rick Dempsey, and studio host Tom Davis, and added Ben McDonald as a secondary analyst.[36][37][38] Starting in 2022, Kevin Brown becomes the primary TV play-by-play announcer, with Garceau, Arnold or Newman the backups.[39]

The Orioles severed their ties with Comcast SportsNet Mid-Atlantic (now NBC Sports Washington) at the end of the 2006 season in favor of MASN, a joint venture with the Washington Nationals. It had been the Orioles' cable partner since 1984, when it was known as Home Team Sports. The Orioles and the Washington Nationals have been in a dispute since the early 2010s, MASN is owned by both teams with the Orioles holding an 80% stake. The dispute which is ongoing as of October 2020 contends that the Nationals deserves a greater fee from MASN due to the team's recent success and market growth. When fees paid to each team were first negotiated, both teams were paid the same fees.[40]

WJZ-TV was the Orioles' broadcast TV home, completing its latest stint from 1994 through 2017. Since MASN acquired rights in 2007, its coverage was simulcast on WJZ-TV under the branding "MASN on WJZ 13". MASN elected not to syndicate any Orioles or Washington Nationals games to broadcast television for the 2018 season, marking the first time since the Orioles' arrival that their games are not on local broadcast television.[41]

Previously, WJZ-TV carried the team from their arrival in Baltimore in 1954 through 1978. In the first four seasons, WJZ-TV shared coverage with Baltimore's other two stations, WMAR-TV and WBAL-TV. The games moved to WMAR from 1979 through 1993 before returning to WJZ-TV. From 1994 to 2009, some Orioles games aired on WNUV.

Since its introduction at games by the "Roar from 34", led by Wild Bill Hagy and others, in the late 1970s, it has been a tradition at Orioles games for fans to yell out the "Oh" in the line "Oh, say does that Star-Spangled Banner yet wave" in "The Star-Spangled Banner".[42] "The Star-Spangled Banner" has special meaning to Baltimore historically, as it was written during the Battle of Baltimore in the War of 1812 by Francis Scott Key, a Baltimorean.

The tradition is often carried out at other sporting events, both professional and amateur, and even sometimes at non-sporting events where the anthem is played, throughout the Baltimore/Washington area and beyond. Fans in Norfolk, Virginia, chanted "O!" even before the Tides became an Orioles affiliate. The practice caught some attention in the spring of 2005, when fans performed the "O!" cry at Washington Nationals games at RFK Stadium. The "O!" chant is also common at sporting events for the various Maryland Terrapins teams at the University of Maryland, College Park. At Cal Ripken Jr.'s induction into the National Baseball Hall of Fame, the crowd, composed mostly of Orioles fans, carried out the "O!" tradition during Tony Gwynn's daughter's rendition of "The Star-Spangled Banner". Additionally, a faint but audible "O!" could be heard on the television broadcast of Barack Obama's pre-inaugural visit to Baltimore as the national anthem played before his entrance. A resounding "O!" bellowed from the nearly 30,000 Ravens fans who attended the November 21, 2010, away game at the Carolina Panthers' Bank of America Stadium in Charlotte, North Carolina.[43] A similar loud "O!" was heard from fans attending Super Bowl XLVII between the Baltimore Ravens and the San Francisco 49ers.[44] The "O!" chant was also heard during the 2016 Summer Olympics in Rio de Janeiro, Brazil, when Baltimore native Michael Phelps received his gold medal for the 4×200 m freestyle on August 9, 2016.[45]

In recent years, when the Orioles host the Toronto Blue Jays, fans have begun to shout out the multiple instances of the word "O" in "O Canada". Washington Capitals fans will do the same when they play one of the NHL's Canadian teams.

It has been an Orioles tradition since 1975 to play John Denver's "Thank God I'm a Country Boy" during the seventh-inning stretch.

In the edition of July 5, 2007, of Baltimore's weekly sports publication Press Box, an article by Mike Gibbons covered the apocryphal details of how this tradition came to be.[46] During "Thank God I'm a Country Boy", Charlie Zill, then an usher, would put on overalls, a straw hat, and false teeth and dance around the club level section (244) that he tended to. He also has an orange violin that spins for the fiddle solos. He went by the name Zillbilly and had done the skit from the 1999 season until shortly before he died in early 2013. Of course, that does nothing to explain why the Orioles' Audio staff began playing the song during every game's seventh inning stretch beginning in August, 1975.

In reality, the song was tremendously successful nationwide, topping the Billboard Top 100 for one week in 1975, and was played in stadiums across the country. The Orioles were chasing the Red Sox for the American League East Division title and incorporated numerous "good luck charms." After an inspiring comeback win, Oriole staff began playing this song at the seventh-inning stretch of every home game as one of the good-luck charms, beginning in August.

During a nationally televised game on September 20, 1997, Denver himself danced to the song atop the Orioles' dugout, one of his final public appearances before dying in a plane crash three weeks later.[47]

Songs from notable games in the team's history include "One Moment in Time" for Cal Ripken's record-breaking game in 1995, as well as the theme from Pearl Harbor, "There You'll Be" by Faith Hill, during his final game in 2001. The theme from Field of Dreams was played at the last game at Memorial Stadium in 1991, and the song "Magic to Do" from the stage musical Pippin was used that season to commemorate "Orioles Magic" on 33rd Street. During the Orioles' heyday in the 1970s, a club song, appropriately titled "Orioles Magic (Feel It Happen)", was composed by Walt Woodward,[48] and played when the team ran out until Opening Day of 2008. Since then, the song (a favorite among all fans, who appreciated its references to Wild Bill Hagy and Earl Weaver) is played (along with a video featuring several Orioles stars performing the song) only after wins. Seven Nation Army is played as a hype song while the fans chant the signature bass riff as a rally cry during key moments of a game or after a walk-off hit.

During the Orioles' final homestand of the season, it is a tradition to display a replica of the 15-star, 15-stripe American flag at Camden Yards. Prior to 1992, the 15-star, 15-stripe flag flew from Memorial Stadium's center-field flagpole in place of the 50-star, 13-stripe flag during the final homestand. Since the move to Camden Yards, the former flag has been displayed on the batters' eye. During the Orioles' final home game of the season, The United States Army Field Band from Fort Meade performs the National Anthem prior to the start of the game. The Band has also played the National Anthem at the finales of three World Series in which the Orioles played: 1970, 1971 and 1979. They are introduced as the "First Army Band" during the pregame ceremonies.

The Orioles will retire a number only when a player has been inducted into the Hall of Fame with Cal Ripken Jr. being the only exception.[N 1] However, the Orioles have placed moratoriums on other former Orioles' numbers following their deaths (see note below).[64] To date, the Orioles have retired the following numbers:

Frank Robinson RF Coach, Mgr Retired 1972 Brooks Robinson 3B   Retired April 14, 1978 Earl Weaver Coach, Mgr   Retired September 19, 1982 Jim Palmer P   Retired September 1, 1985 Eddie Murray 1B, DH   Retired June 7, 1998 Cal Ripken Jr. SS, 3B   Retired October 6, 2001 Jackie Robinson† All MLB   Honored April 15, 1997

Note: Cal Ripken Sr.'s number 7, Elrod Hendricks' number 44, and Mike Flanagan's number 46 have not officially been retired, but a moratorium has been placed on them and they have not been issued by the team since their deaths.

^†Jackie Robinson's number 42 is retired throughout Major League Baseball

The Orioles also have an official team hall of fame, located on display on Eutaw Street at Camden Yards. The most recent inductee was fan Mo Gaba in 2020.[65]
