Alonso agreed to terms on a two-year, $54 million contract with the Mets on Wednesday, Jeff Passan of ESPN.com reports.
Alonso previously rejected a three-year deal worth roughly $70 million, but the 30-year-old slugger will end up remaining in New York for the foreseeable future as the Mets' everyday first baseman. His new deal will pay him $30 million in 2025 and includes an opt-out after the first season, which could allow him to enter free agency once again next winter.
