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 would become 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.
