Boston had an 11-game winning streak from May 28 through June 8, to put themselves in the AL lead. While they briefly fell into second place in mid-June, behind Philadelphia, Boston then won 9-of-10 to recapture the lead, which they held through the end of the season. The Americans met the Pittsburgh Pirates in the first modern World Series, an agreement between the AL and the NL as a post-season tournament. The "Amerks" won the best-of-nine series series in eight games; after falling behind, 3–1, they won four games in a row, clinching the championship at their home field, the Huntington Avenue Grounds, in Boston.
The first championship of what is now 9 for the long-running club, the series would immortalized in the 2004 remake of the team's fight song Tessie by The Dropkick Murphys, honoring the victory over the Pirates in Game 5, helped in part by that song which was adopted as an anthem by the a group of team supporters, the Royal Rooters, under saloon owner Michael T. McGreevy.
Boston won the series, 5–3.
