Alonso has kicked off the 2025 MLB campaign on a high note. He is currently hitting with a .292 batting average, with three home runs, ten RBIs, and a healthy OPS of 1.183. The four-time All-Star will hope to continue his dominant start at the plate as the eternal underdogs of baseball chase the NL pennant after falling short last season.
The Mets are currently 5-3 for the season, and with their latest win against the Blue Jays on Saturday night at Citi Field, they registered back-to-back series wins after opening the 2025 season with a series loss against the Astros in Houston.
