The Pirates started Game 1 strong, scoring six runs in the first four innings. They extended their lead to 7–0 on a solo home run by Jimmy Sebring in the 7th, the first home run in World Series history. Boston tried to mount a comeback in the last three innings, but it was too little, too late, as they ended up losing by a score of 7–3 in the first ever World Series game. Both starting pitchers, Deacon Phillippe of the Pirates and Cy Young of Boston, threw complete games, with Phillippe striking out 10 and Young fanning 5, but Young also gave up twice as many hits and allowed 3 earned runs to Phillippe's 2.

After starting out strong in Game 1, the Pirates simply shut down offensively, managing to get a meager 3 hits, all of which were singles. Pirates starter Sam Leever went only one inning and gave up 3 hits and 2 runs before being replaced by Bucky Veil in the second inning due to injury, who finished the game for Pittsburgh. Bill Dinneen struck out 11 and pitched a complete game for the Americans, while Patsy Dougherty hit home runs in the first and sixth innings to produce 2 of the Boston's 3 runs.

Deacon Phillippe, pitching on only one day rest, started Game 3 for the Pirates, and did not let them down as he pitched his second complete-game victory of the series to put the Pirates up two games to one.

After two days of rest, Deacon Phillippe was ready to pitch his second straight game. He threw his third complete-game victory of the series against Bill Dinneen, who was pitching in his second start of the series. However, Phillippe's second straight victory was almost not to be, as the Americans, down 5–1 in the top of the ninth, staged a rally to bring the game within one. The comeback attempt failed, though, as Phillippe managed to put an end to it and give the Pirates a commanding 3–1 series lead.

Game 5 was a pitcher's duel for the first five innings, with Boston's Cy Young and Pittsburgh's Brickyard Kennedy giving up no runs. That changed at the top of the sixth, however, when the Americans scored a then-record 6 runs that inning. Young, on the other hand, managed to keep his shutout intact before finally giving up a pair of runs in the bottom of the eighth. He went the distance and struck out four for his first World Series win.

Game 6 featured a rematch between the starters of Game 2, Bill Dinneen (Boston) and Sam Leever (Pittsburgh). This time, Leever would pitch the entire game, but despite throwing a complete game he was outmatched by Dinneen, who ended up with his second complete-game victory of the series. After losing three of the first four games of the World Series, the underdog Boston Americans had tied the series at three games apiece.

The fourth and final game in Allegheny City saw Deacon Phillippe start his fourth game of the series for Pittsburgh. This time, however, he wouldn't fare as well as he did in his first three starts. Cy Young, pitching in his third start of the series, would face a much more favorable fate, holding the Pirates to only three runs.

The final game of the inaugural World Series started out as an intense pitcher's duel, with no runs being scored until the fourth inning – when a Hobe Ferris single scored two runners. Deacon Phillippe started his fifth and final game of the series, while Bill Dinneen started his fourth game of the series. As he did in Game 2, Dinneen threw a complete-game shutout while striking out seven, leading the Boston Americans to victory, while Phillippe, who also threw a respectable game, just couldn't pitch at Dinneen's level due to wearing out his arm in the series (as a result of playing so many games in such a short time span) and gave up three runs in the defeat. Honus Wagner struck out to end the Series.
