In 1912 Bender was 13–8 with a 2.74 ERA. He did not start for nearly 40 games late in the year and was suspended by the A's in September for alcohol abuse. His next contract had a clause saying he had to abstain from drinking to earn his full salary. In 1913, he went 21–10 with a 2.21 ERA, helping the A's win their third AL pennant in four years. They would also make it three World Series titles in four years by defeating the Giants in five games. Bender went 2–0 in the series with complete-game victories in Games 1 and 4.
