Mets To Sign Jorge Polanco

The Mets and free agent infielder Jorge Polanco have agreed to a two-year contract, The Athletic’s Will Sammon reports (multiple links).  The deal is worth $40MM, according to ESPN’s Jeff Passan.  Polanco is represented by the Octagon Agency.

It’s a big strike for a Mets team that lost Pete Alonso and Edwin Diaz to free agency just within the last week, not to mention last month’s trade that sent another longtime Met in Brandon Nimmo to Texas.  New York acquired Marcus Semien in the Nimmo deal, and while Polanco also has a long history of playing second base, Passan writes that the Mets will deploy Polanco primarily as a first baseman and DH.  Polanco could also potentially chip in at third base, though it looks as it the Mets view Polanco a piece of the puzzle in replacing Alonso at first base.

The 32-year-old Polanco hit .265/.326/.495 with 26 home runs over 524 plate appearances for the Mariners last season, playing a huge role for a Seattle team that won the AL West and fell just short of reaching the World Series.  It was a fine bounce-back performance for Polanco after a down year in 2024, which still resulted in a one-year guarantee to return to the Mariners in 2025.  That deal paid Polanco $7.75MM in guaranteed money, and he made enough plate appearances to turn an $8MM mutual option for 2026 into a $6MM player option, and Polanco unsurprisingly rejected that player option to re-enter the market after his much improved platform year.

The 132 wRC+ Polanco posted in 2025 was the highest of his career, and he drastically cut back on his strikeouts after seeing his K% balloon in each of the previous four seasons.  While Polanco walked less than usual, his 45.8% hard-hit ball rate was a career best.  Overall, the advanced metrics suggest that Polanco’s resurgence in 2025 was legitimate, and if anything, his .269 BABIP indicates that he perhaps deserved even better numbers.

One concern within Polanco’s otherwise strong year was that he made 89 appearances as a designated hitter, after amassing only 45 DH days over his 11 previous big league seasons.  Polanco sustained an oblique injury early in the 2025 season that wasn’t quite serious enough to merit a trip to the injured list, but the Mariners compensated by using Polanco less frequently in the field, and cut back on the switch-hitter’s usage against left-handed pitching.

While there hasn’t been any concern that Polanco will be similarly limited going forward, the Mets’ plan to use him as a first baseman may also reflect Polanco’s age, his modest defensive numbers as a second or third baseman, and the fact that a stellar fielder like Semien is already in place at the keystone.  Throughout his long pro career, Polanco has made exactly one career appearance as a first baseman, and it was just a late-game cameo for a single at-bat in Seattle’s 5-4 loss to the Giants last April 6.

Polanco is an experienced enough infielder that the Mets obviously feel he’ll be able to learn the position in due course.  For all of Alonso’s pluses at the plate, he was a poor enough fielder that Polanco will be a defensive upgrade even if he’s just an average first baseman.

However, between losing both Alonso and Nimmo, the Mets’ offense has taken hit by essentially replacing the duo with Polanco and Semien, given how Semien struggled in 2025.  Run prevention has been a stated goal for Mets president of operations David Stearns, and upgrading the defense is another way of making the lineup better, even if the team will still need to add some more pop as the offseason develops.
