In a rematch of the 1905 World Series, the Athletics got their revenge, defeating the New York Giants and becoming the first American League team to win back-to-back World Series (the Chicago Cubs from the NL had won back-to-back titles in 1907 and 1908). After losing the opener 2–1 to Christy Mathewson, though pitching a complete game, giving up just 5 hits and 2 runs (1 earned run) and striking out 11, he returned in Game 4, beating the Giants 4–2 on a complete game 7-hitter, and closed out the Series in game 6 with a 13–2 A's victory. Bender again went the distance (his 3rd complete game of the series), a 4-hit performance which he gave up no earned runs (the two Giants runs were unearned). He went 2–1, with 1.04 ERA and 3 complete games in the series.
