Pete Alonso reached 300 career home runs Tuesday night with a solo shot off Kodai Senga in the ninth inning, tying the game and earning him a curtain call at Citi Field. Per multiple outlets, Alonso became the 19th active player to reach the milestone. The game remained tied through the end of regulation and into extra innings.
Coby Mayo's inside-the-park home run in the top of the 11th inning broke the tie and sent the Baltimore Orioles to a 7-5 victory over the Mets. Per ESPN's reporting, Alonso's tying shot came against his former team, the Orioles.
After the game, Alonso met with three Mets fans who had caught his 300th home run, exchanging the ball for signed memorabilia and offering the group tickets to upcoming games in Baltimore, according to a report on r/baseball.
