After appearing in 12 games for the Tigers in 1913 and playing in the minor leagues in 1914, he was purchased by the Yankees before the 1915 season. They made him their starting first baseman. He and Home Run Baker led an improved Yankee lineup that led the league in home runs. He led the American League in home runs in 1916 and 1917. With Babe Ruth, Bob Meusel, Joe Dugan, and Waite Hoyt, the Yankees won three consecutive American League pennants from 1921 through 1923, and won the 1923 World Series. In 1925, he lost his starting role to Lou Gehrig, after which he finished his major league career with Cincinnati.
