Heilmann returned to the Tigers in 1916 and appeared in 136 games, including 30 games at first base and 77 as an outfielder. Although his .282 batting average was low by the standards he would set later, he ranked among the American League leaders with 30 doubles (seventh best), 77 RBIs (sixth best) and 43 extra base hits (eighth). He also became a favorite in Detroit for his actions off the field. On July 25, 1916, he saved a woman whose vehicle had rolled into the Detroit River, diving into the water to rescue her, although two others died in the accident. His heroic act was reported in the national press, and he was loudly applauded at the next day's game.
