On September 3, 2006, In the opener of a doubleheader at Citizens Bank Park, Philadelphia’s Ryan Howard belts three home runs, bringing the first baseman’s total to 52. The sophomore slugger, the 24th major leaguer to reach the milestone, becomes the first Phillies player to hit 50 home runs breaking the Phillies’ single-season record (48), held previously by Hall of Famer Mike Schmidt.

He also passes Ralph Kiner, who hit 51 for the Pirates in 1947, for the most homers hit by a second-year player in big league history.
