after defeating star Philadelphia Athletics left-hander Rube Waddell in a postseason exhibition game played sometime between 1902 and 1905. A newspaper story in the Trenton (NJ) Times from July 26, 1904, contains the earliest known example of Foster being referred to as "Rube," indicating that the supposed meeting with Waddell must have taken place earlier than that. Recent research has uncovered a game played on August 2, 1903, in which Foster met and defeated Waddell while the latter was playing under an assumed name for a semipro team in New York City. Foster, now a star, jumped to the Philadelphia Giants for the 1904 season. Legend has it that John McGraw, manager of the New York Giants, hired Foster to teach the young Christy Mathewson the "fadeaway", or screwball, though historians have cast doubt on this story. During the 1904 season, Foster won 20 games against all competition (including two no-hitters) and lost six. In a rematch with Foster's old team, the Cuban X-Giants, he won two games and batted .400 in leading the Philadelphia Giants to the black championship. In 1905, Foster—by his own account several years later—compiled a fantastic record of 51–4 (though recent research has confirmed only a 25–3 record) and led the Giants to another series championship, this time over the Brooklyn Royal Giants. The Philadelphia Telegraph wrote that "Foster has never been equalled in a pitcher's box." The following season, the Philadelphia Giants helped form the International League of Independent Professional Ball Players, composed of both all-black and all-white teams in the Philadelphia and Wilmington, Delaware, areas. Leland Giants In 1907, Foster's manager Sol White published his Official Baseball Guide: History of Colored Baseball, with Foster contributing an article on "How to Pitch." However, before the season began, he and several other stars (including, most importantly, the outfielder Pete Hill) left the Philadelphia Giants for the Chicago Leland Giants, with Foster named playing manager. Under his leadership, the Lelands won 110 games (including 48 straight) and lost only ten, and took the Chicago City League pennant. The following season the Lelands tied a national championship series with the Philadelphia Giants, each team winning three games. Foster suffered a broken leg in July 1909, but rushed himself back into the lineup in time for an October exhibition series against the Chicago Cubs. Foster, pitching the second game, squandered a 5–2 lead in the ninth inning, then
