How J.D. Martinez’s Return To The Mets Organization Could Prove Beneficial To Mark Vientos

Earlier this week, the New York Mets announced that J.D. Martinez was being brought back as a special assistant to baseball operations, similar to the role Carlos Beltran has. Martinez was a crucial part of the Mets 2024 postseason run, not just as a player, but as a clubhouse leader. In particular, his veteran leadership that season appeared to really impact one player on the team: Mark Vientos.

In 2024, Mark Vientos exploded onto the scene after he was called up in mid-May, making an enormous statement despite failing to make the Opening Day roster. He slashed .266/.322/.516 with 27 home runs that season and later set the Mets' postseason record in RBIs with 14.

The two go way back, both being from the South Florida area and working out at the same facility over the offseason. When asked about Martinez’s impact on Vientos, manager Carlos Mendoza took the time to laud the now-retired slugger.

It's never been a secret that their relationship was strong. Vientos told the New York Post that he always tried to relay information of the veteran when they played together: “Hey, J.D., what were your thoughts when you were my age, on this and that. I take what I think will work for me and leave what I don’t think will work for me and that is just how I go about asking questions.” 

In 2025, Martinez stepped away from baseball. With him gone and the ever dangerous “sophomore slump” looming, Vientos had sky high expectations and was unable to meet them. He registered -0.2 WAR in 121 games, slashing .233/.289/.413 with 17 home runs. Then, those struggles extended to this spring, when the 26-year-old recorded a .040 batting average. Vientos was also nonexistent in the World Baseball Classic, only recording two hits with Nicaragua being eliminated in the group stage.

In the opening series of the season, Vientos only received one at-bat, coming off the bench in the 10th inning. However, with the entire offense rooted in a slump, he has been getting increased playing time in recent contests and has responded to the call, posting extra-base hits in back-to-back contests.

For Vientos to fully resort back to his 2024 form, when he ranked in the 88th percentile in batting run value and 92nd percentile in barrel rate, bringing back a mentor like Martinez is as good a place to start as anywhere.
