Babe Ruth was a great left-handed pitcher who became an even better power hitter. He held the season and lifetime home run records for a long time. The ad for this short subject also mentions Babe's teammate "Pitcher Carl Mays/His Underhand Delivery Shown in Every Movement." This was added because the month before, Mays hit Ray Chapman of the Cleveland Indian in the head. Chapman became the only major leaguer to die from being hit by a pitched ball.
