The 1904 club was almost as good as the previous team, but due to the surprise emergence of the New York Highlanders, the Boston club found itself in a tight pennant race through the last games of the season. A predecessor to what became a storied rivalry, this race featured such controversial moves as the trade of Patsy Dougherty to the Highlanders for Bob Unglaub. The climax of the season occurred on the last, dramatic doubleheader at the Highlanders' home stadium, Hilltop Park. In order to win the pennant, the Highlanders needed to win both games. With Jack Chesbro, the Highlanders' 41-game winner, on the mound, and the score tied 2–2 with a man on third in the top of the ninth, a spitball got away from Chesbro and Lou Criger scored the go-ahead run on one of the most famous wild pitches in history.
