Pete Alonso: 2025 MLB Free Agent Profile
The Polar Bear’s Career
Alonso debuted for the Mets out of spring training in 2019, and took the National League by storm. In 2019, he posted 53 home runs, which led all of MLB and set the rookie record for home runs. Alonso took home the 2019 National League Rookie of the Year honors for his accomplishment.Â
Throughout his career with the Mets, he proved himself as one of the most feared hitters in baseball. Alonso was the heart and soul of the Mets lineup and a fan favorite. During the 2023 season, the Mets offered Alonso a contract to keep him in Queens long term. He declined the seven-year, $158 million offer. Alonso then hired superstar agent Scott Boras for his negotiations prior to hitting free agency after the 2024 season.
The Mets overachieved in 2024 from June on, and made the postseason on the last day of the season, though Alonso did not have his best year. It did not matter, though, because Alonso came through when it mattered the most. In the top of the ninth inning, down to their last two outs in the Wild Card Series against the Milwaukee Brewers, Alonso jacked a go-ahead three-run home run off Devin Williams, sending the Mets to a win. The Mets would go on a surprise October run before falling to the eventual world champion Los Angeles Dodgers in six games in the NLCS.
Alonso would hit free agency, and after a long saga where everyone thought he was destined to leave Queens, he ended up back with the Mets on a two-year deal with an opt-out clause.
2025 Season
Alonso delivered a resurgent season in 2025, firmly re-establishing himself as a premier power bat for the Mets. He posted a 272 batting average, 38 home runs, and 126 RBI. This ranked among the National League’s top offensive contributors. Additionally, Alonso’s advanced metrics reflected his dominant mode at the plate: a hard-hit rate over 53 percent and a barrel rate near 19 percent.
Beyond the raw numbers, the season was defined by two major milestones. First, Alonso broke the Mets’ all-time franchise home run record with his 253rd, surpassing Darryl Strawberry’s record. Second, his consistency shone through as he became one of just a few players in the league to drive in over 120 runs, finishing second in the National League in RBI. Despite the team missing the playoffs, Alonso’s individual season was a standout campaign. His 2025 season positioned him for perhaps his most significant free-agency window yet.

One thing that does not reflect in the hitting metrics is his defense. Alonso is a minus defender at first base and will likely be a primary DH before long. While Alonso can hold down the position if needed, issues with his range and throwing came up on multiple occasions for the Mets, including a high throw causing an injury to starter Kodai Senga, derailing his and the Mets’ season.

Contract Outlook
Alonso is projected to receive a four to five-year contract, in the $110-$150 million range. It’s worth noting that reports from the New York Post indicated earlier that agent Scott Boras was looking for a seven-year deal. It’s unlikely any team will give that length to Alonso. There are many suitors for Alonso, including the New York Mets, Philadelphia Phillies, San Francisco Giants, Boston Red Sox, Chicago Cubs, and Arizona Diamondbacks.
