Baltimore Orioles first baseman Pete Alonso hit his three hundredth career home run Tuesday night against his former team, the New York Mets, at Citi Field. Trailing in the ninth inning, Alonso launched a four hundred fourteen foot solo drive off reliever Kodai Senga to tie the game at three. The milestone made Alonso the nineteenth active player to reach the mark and joined him with select company in baseball history. The Orioles ultimately secured a seven to five victory in eleven innings after Coby Mayo hit a tiebreaking inside the park home run. New York suffered its third consecutive loss and confirmed a losing season, while Baltimore maintained its pursuit of an American League wild card berth. Alonso received a warm curtain call from the twenty eight thousand attendees, highlighting his enduring popularity in Queens following his departure in free agency last December. This historic moment highlighted the game.
