H2: Alonso set to join the Orioles
Sources tell ESPN reporter Jeff Passan that first baseman Pete Alonso and the Baltimore Orioles are finalizing a five-year, $155 million contract. The agreement, if completed, would mark a notable free-agent signing for Baltimore and close Alonso’s second straight trip to free agency.
H3: 2025 rebound and Mets history
Alonso, who turned 31 in December, rebounded strongly in 2025 after a difficult 2024. He slashed .272/.347/.524 with 38 home runs and 126 RBIs while hitting behind Juan Soto for the first time. That output included the best xwOBA of his career and reflected fewer strikeouts and increased power as Alonso shortened his swing.
In August 2025, Alonso became the New York Mets’ all-time leader in home runs, surpassing Darryl Strawberry’s 252. The five-time All-Star broke into the big leagues with a 53-homer rookie season in 2019 and remained a central offensive figure in Queens for six seasons.
H4: Contract background and opt-out
Alonso made $30 million with the Mets in 2025 and opted out of the remaining $24 million on his contract to test the market again. He had previously rejected a seven-year, $158 million extension from the Mets in the summer of 2023 while seeking a longer-term deal.
While Alonso’s offense rebounded, his baserunning and defensive metrics showed continued regression, largely due to decreased range at first base. Still, his 2025 power numbers and improved strikeout rate helped restore his value to contenders in free agency.
H4: What experts are saying
ESPN’s reporting cites multiple sources and contributions from Jorge Castillo and Kiley McDaniel. The deal was described as surprising by earlier coverage of the winter meetings, reflecting how quickly free-agent dynamics have shifted during the offseason.

This signing, once official, will add a proven power bat to Baltimore’s lineup and close a long-running chapter in Alonso’s time with the Mets. The move also continues a busy free-agent period that has reshaped several rosters across MLB.
