The Mets have added another potent, back-end arm to a bullpen that looks strong. 

Ryne Stanek, who was a force during the Mets’ postseason run, has agreed to return on a one-year pact, a source confirmed.

The deal is pending a physical and worth $4.5 million with incentives that can bump it to $5 million, according to MLB.com. 

The righty projects as a complement to lefty A.J. Minter, both bridges to closer Edwin Diaz. The Mets bullpen also will have Reed Garrett, Dedniel Nunez, Sean Reid-Foley, Danny Young and perhaps Jose Butto, among other possibilities.

The group rated as the 13th-most valuable bullpen in the majors last season, by FanGraphs’ estimation, and on paper at least appears to have taken a step forward. 

Stanek arrived in a midseason trade with the Mariners and struggled to finish the regular season, posting a 6.06 ERA in 17 games.

He was excellent in the postseason, though, in which he allowed three runs in eight innings that included a marathon, seven-out outing in an NLCS Game 5 win over the Dodgers.

The fireballer just kept pitching because the exhausted Mets needed him. 

The 2025 Mets bullpen, which has plenty of fliers from Huascar Brazoban to Tyler Zuber to Dylan Covey, could have used more certainty and hopes it found some in the 33-year-old. 

Stanek is a veteran with eight years of experience and a reputation for big moments, owning a career 2.89 ERA in 28 postseason innings.

During the regular season, he has reliably taken the ball — his 249 relief appearances since 2021 are the 15th-most in baseball — though he has been more hittable over the past two seasons, in which he has logged a combined 4.50 ERA with the Astros, Mariners and Mets. 

Nevertheless, Stanek has continued to miss bats, particularly with an above-average splitter and slider and a fastball that climbs into the upper 90s. 

After the Dodgers knocked out the Mets in the NLCS, Stanek said he would remember the clubhouse of “really, really good people” with whom he meshed well. He now will have a chance to run it back in Queens. 

“It was a really special group,” Stanek said after Game 6. “It was a lot of fun. I really enjoyed everybody here. It was tough because New York is obviously not the easiest place to get comfortable and get used to, and getting traded over here in the middle of the season, moving my family across the country — and everybody, from the staff to the players to the sports staff, everybody was super welcoming and made the transition incredibly easy.”
