Pete Alonso of the New York Mets became the first player in franchise history to hit 30 home runs in a season before the All-Star break. The first baseman reached the milestone with a solo shot off of Miami Marlins pitcher Pablo Lopez on June 21, 2019, at Citi Field. Alonso's historic power display helped solidify his status as one of the National League's most feared sluggers and set the stage for a Rookie of the Year campaign that saw him finish with 53 home runs, breaking the Mets' single-season record previously held by Todd Hundley.
