After having played for six seasons in Buffalo, he made his major league debut with the Yankees on May 18, 1923 at the age of 24. 1923 was also the first year the Yankees played their home games in Yankee Stadium. At the beginning of his playing career, Bengough served as a back up catcher to Wally Schang. On June 1, 1925, the same day that Lou Gehrig replaced Wally Pipp as the Yankees' first baseman, Bengough was given the Yankees' starting catcher's job. He ended the season with a .258 batting average along with a career-high 14doubles and 23 runs batted in.
