Pete Alonso, a five-time All-Star and one of MLB's premier power hitters, is set to join the Baltimore Orioles on a five-year, $155 million contract, according to sources. Alonso, who opted out of his previous Mets contract following their disappointing 2025 season, had been in free agency for the second consecutive year. His new deal does not include any opt-outs, and the Orioles reportedly matched or slightly exceeded the offer the Phillies made to Kyle Schwarber, which was also five years for $150 million. Alonso's 2025 season was one of his best offensively, with a .272/.347/.524 slash line, 38 home runs, and 126 RBIs, rebounding from a down year in 2024. He became the Mets' all-time home run leader this season with 253 career homers, surpassing Darryl Strawberry. Alonso's career includes 264 home runs, third most in MLB since his debut in 2019, and multiple Home Run Derby wins. The Orioles aim to bolster their lineup with Alonso's power, though they still need to strengthen their rotation and bullpen. Alonso's departure marks a significant change for the Mets, who have traded key players and missed the postseason in 2025, signaling a major roster overhaul.
