Chris Bosio

Bosio played in Milwaukee's farm system for the 1982 through 1985 seasons, and partially during 1986, the year of his MLB debut. After playing for Rookie League and Class A Beloit Brewers teams through 1984, Bosio spent 1985 with the Double-A El Paso Diablos, compiling an 11–6 record in 28 games (25 starts). In 1986, he spent most of the season with the Triple-A Vancouver Canadians, appearing in 44 games (all in relief); he had a 7–3 record with a 2.28 ERA in 67 innings pitched.

Bosio made his MLB debut on August 3, 1986, against the Texas Rangers. He pitched three innings in relief, giving up three hits and one run, with one strikeout, Pete Incaviglia.[3] He made a total of 10 appearances (four starts) with the 1986 Brewers, with a 7.01 ERA and an 0–4 record.

In 1987, Bosio had an 11–8 record with 5.24 ERA in 46 appearances (19 starts). His record fell to 7–15 in 1988, when he made 38 appearances (22 starts) with a 3.36 ERA. In 1989, his record improved to 15–10, when he appeared in 33 games (all starts) and had a 2.95 ERA.

In 1990, Bosio's 20 appearances were all starts; he pitched to a 4–9 record with a 4.00 ERA. In 1991, his record improved to 14–10 with a 3.25 ERA, in 32 games played (all starts). His record further improved to 16–6 in 1992, with a 3.62 ERA in 33 appearances (all starts).

In seven seasons with the Brewers, Bosio appeared in 212 games (163 starts) with an overall record of 67–62, 749 strikeouts, 289 walks, and a 3.76 ERA in 1190 innings pitched.

Bosio became a free agent after the 1992 season.[4]

The Seattle Mariners signed Bosio in December 1992.

On April 22, 1993, Bosio was the second pitcher in Mariners' history to pitch a no-hitter, when he retired 27 straight Boston Red Sox batters after walking the first two.[5] The last out was made when shortstop Omar Vizquel bare-handed a high chopper over the mound by Ernest Riles and threw him out.[6] It stood as the most recent no-hitter for the Mariners until the team's six-pitcher effort against the Los Angeles Dodgers on June 8, 2012, as well as the most recent no-hitter by a single Mariners pitcher until Félix Hernández's perfect game on August 15, 2012. On June 25, 1993, Bosio made the only non-pitching appearance of his career, entering a game against the Chicago White Sox as a pinch runner for Bret Boone; he did not have a plate appearance.[7] Manager Lou Pinella inserted Bosio in the game to qualify as an appearance, so Bosio could subsequently start serving a pending suspension for his involvement in a brawl.[8] With the 1993 Mariners, Bosio appeared in 29 games (24 starts), compiling a 3.45 ERA and a 9–9 record.

In 1994, Bosio had a 4–10 record with 4.32 ERA in 19 games (all starts). His record improved to 10–8 in 1995, when he played in 31 games (all starts) and had a 4.92 ERA. Bosio's only postseason appearances were in 1995. He started two games in the ALDS against the New York Yankees, pitching a total of 7+2⁄3 innings and giving up nine earned runs (10.57 ERA); he did not record a win or a loss. Seattle advanced to the ALCS, losing in six games to the Cleveland Indians. Bosio started Game 5, giving up three runs (two earned) in 5+1⁄3 innings and taking the loss.[9]

Bosio had a career-high 5.93 ERA in 1996, when he appeared in 18 games (nine starts) with a 4–4 record. He was granted free agency in November 1996.

In four seasons with the Mariners, Bosio appeared in 97 games (83 starts) with an overall record of 27–31, 310 strikeouts, 192 walks, and a 4.43 ERA in 520 innings pitched.

In August 1997, Bosio signed with the Boston Red Sox organization,[10] making two appearances with their Rookie League team, and one appearance in Class A-Advanced.[11] At the time, he had undergone a total of nine knee surgeries during his career.[10] Bosio did not pitch professionally after the 1997 season.[11]
