# 1903 Boston Americans season

The 1903 Boston Americans season was the third season for the professional baseball franchise that later became known as the Boston Red Sox. The Americans finished first in the American League (AL) with a record of 91 wins and 47 losses, 14+1⁄2 games ahead of the Philadelphia Athletics. Boston went on to participate in the first World Series held between the AL and National League (NL) champions. The Americans won the 1903 World Series in eight games over the Pittsburgh Pirates. The team was managed by Jimmy Collins and played its home games at Huntington Avenue Grounds.

## Offseason and Spring Training
### Transactions

* October 6, 1902: It is reported that George Stone will play for the Boston Americans.
* October 28, 1902: John McGraw, manager of the New York Giants, announces that Jack Warner of the Boston Americans had signed to play for the Giants. This decision came after weeks of speculation as to the future of Jack Warner. In an interview printed on September 25, 1902, Jimmy Collins stated that he had signed Warner to a two-year contract with the Americans the previous month. On October 13, 1902, Jimmy Collins had gone to New York after hearing reports that Warner had jumped to the New York Giants.
* March 18, 1903: Catcher Charles "Duke" Farrell announces that he has accepted an offer to play for the Boston Americans.
Prior to the regular season, the team held spring training in Macon, Georgia. Cy Young was a coach for the Mercer University baseball team, also based in Macon.
The Boston Americans played an exhibition game against Mercer University (with Cy Young pitching for Mercer) on March 23; the outcome being a 13─2 victory for Boston.

## Regular Season Overview

* June 30: Nick Altrock starts and pitches eight innings in a 10–3 road loss to the Chicago White Sox; these are the only innings in the entire season not pitched by members of the five-man rotation, led by Cy Young.

## World Series

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 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 be 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 a group of team supporters, the Royal Rooters, under saloon owner Michael T. McGreevy.

### Summary

Boston won the series, 5–3.
