Pete Alonso hit his 54th home run of the season on September 23, 2023, leading the New York Mets to a 6-2 victory over the Miami Marlins. The first baseman's milestone blast came in the seventh inning off Marlins reliever Andrew Nardi, giving him sole possession of 10th on the all-time single-season home run list. Alonso, who had been tied with Aaron Judge at 53, now stands alone in the top 10 for most homers in a single year in MLB history. The Mets' slugger has been a force all season, driving in 131 runs and hitting .266 with 138 runs scored. His historic power display has been a bright spot for New York, which has struggled to stay in playoff contention.
