For the second day in a row, the New York Mets have seen a beloved star agree to terms with another team.

Pete Alonso, the Mets’ all-time leader in home runs, has reportedly agreed to a five-year, $155m contract with the Baltimore Orioles. The news comes a day after the Mets’ long-term closer, Edwin Díaz, reached a three-year deal with the Los Angeles Dodgers.

The 31-year-old slugger had been unable to find a long-term deal last season and returned to the Mets on a shorter contract, which he opted out of after this year’s World Series. While the Mets were interested in re-signing him they reportedly never made an offer once other teams were willing to offer longer, more valuable deals to the the first baseman.

Alonso has spent his entire MLB career with the Mets, and last season broke Darryl Strawberry’s franchise record for home runs. He ends his Mets career with 264 home runs. He was also incredibly popular with the team’s fans due to his good-nature and power, earning the nickname Polar Bear. The Mets also lost another long-term popular player, Brandon Nimmo, last month in a trade with the Texas Rangers.

Alonso had one of the best offensive seasons of his career in 2025 – he hit .272 with 38 home runs and 126 RBIs – but there are concerns about his defense, a weak point for the Mets, and base running, and the Mets appeared reluctant to give him a multi-year deal when they have already have Juan Soto and Francisco Lindor on expensive, long-term contracts.

Over his Mets career, Alonso hit .253 with 264 home runs and 712 RBIs and an OPS of .857. He was the NL rookie of the year in 2019, when he hit 53 home runs, and a five-time All Star.

Alonso joins an Orioles team that finished last in the AL East last season, although they have several young stars such as Adley Rutschman, Gunnar Henderson and Jackson Holliday.
