Pete Alonso Hits 300th Career Home Run Against Former Team Mets at Citi Field
On September 15, 2026, Pete Alonso reached a major career milestone by hitting his 300th home run in dramatic fashion—against his former team, the New York Mets, at Citi Field. The solo shot in the top of the ninth inning tied the game 3-3 and drew an emotional curtain call from the same fans who cheered him for seven seasons. Alonso, now with the Baltimore Orioles, became the 19th active player to reach the 300-homer mark and the 20th in AL/NL history to achieve it against a former club.
