Because the Mets traded or waived nearly all of their pending free agents (Brooks Raley, David Peterson, A.J. Minter, Freddy Peralta, Clay Holmes, and Luis Robert Jr.), the only notable pending free agent is Frankie Montas, whose two-year deal blew up due to a mix of injury and ineffectiveness.
Beyond that, it's possible Bo Bichette will opt out of his contract. But it would be an upset, considering that Bichette would be leaving $84 million on the table ($42 million each of the next two seasons) after posting a 97 OPS+ in order to join a free agent market that could be impacted by an expected lockout.
If Bichette opts in, the Mets' starting outfield alignment and left side of the infield will be set, leaving second base and first base as the main question marks.
With that as a backdrop, it's possible the Mets consider moving on from some of the players who have been roster cogs for the last several seasons but haven't yet established themselves.
One of the players the Mets could part ways with is Mark Vientos.
Vientos, who will be entering his age-27 season in 2027, is arbitration-eligible for the first time.
Will the Mets trade or DFA Vientos this offseason? Should they?

WHY IT COULD MAKE SENSE TO TRADE OR NON-TENDER VIENTOS
Aside from his 2024 season, when it looked like Vientos might be emerging as a lineup regular with serious power potential, it has been a struggle for him in the majors.
Vientos posted a combined .610 OPS in 2022 and 2023 across 81 games in his first taste of the bigs, and he was a below average offensive player in 2025 -- slashing .233/.289/.413 with 17 homers in 121 games.
This past season saw further regression from Vientos at the plate, as he hit just .212/.258/.394 (.652 OPS, 81 OPS+) in 87 games.
His advanced metrics when it came to average exit velocity, hard hit percentage, and barrel percentage remained above average, but Vientos was below average in most other key metrics tracked by Baseball Savant. That included a walk rate that was near the bottom of the league.
Meanwhile, Vientos' defense remained an issue, as he was worth -9 OAA. Almost all of his defensive innings came at first base, where he appeared 67 times (Vientos' other three games in the field were at third base). While Vientos has worked hard to hone his skills defensively, including extensive work at third base, he's been a consistently below average defender for his entire career.
When looking at how New York's roster shapes up now and the possible additions they could make this winter, there doesn't seem to be much room for Vientos.
As things presently stand, first base could be a platoon situation with Jared Young getting the bulk of the at-bats against right-handed pitchers. But given Young's relative lack of power and difficulties against left-handed pitching, it can be argued that the Mets should be seeking a starting first baseman via free agency or trade -- or at the very least a right-handed complement to Young.
The DH situation could also be crowded, with Brett Baty (who could also get time at second base) and Jorge Polanco (health-permitting) among the potential options there. The Mets will also likely look to get Juan Soto off his feet regularly, meaning DH will be his on days he doesn't start in left field.

WHY IT COULD MAKE SENSE TO KEEP VIENTOS
For all of his flaws, Vientos still hits the ball really hard and has legitimate home run power.
Vientos is also under team control for three more seasons and is set to make only $2.4 million in 2027 via arbitration.
And while the DH situation could be crowded, it's also possible the opposite comes to be. In a scenario where the Mets add a legitimate starting first baseman, Baty is starting regularly at second base, and Polanco's injury issues persist, there could be lots of at-bats to go around.
Beyond Vientos, the Mets don't have many other DH options, unless they're prepared to give a serious look to Ronny Mauricio, who is out of options and has never shown any indication his chase rate will drop low enough to make him a viable big league player.
It's also conceivable the Mets keep Vientos as a bench piece/part-time player who can provide right-handed pop.
If the Mets don't make relatively big external additions at first base or DH, it stands to reason that there will be more room for someone like Vientos. If the Mets do add at one or both of those spots, it seems likely Vientos will be squeezed out.

VERDICT
Before Vientos returned from the IL at the end of August, then-interim manager Andy Green was blunt about what his role would be.
"I don't know," Green said. "I was very forthright with him when he started the rehab assignment that a lot of that will be dictated by how others perform and also by how he performs. Still think there’s a very bright future for him out there if he wants to grab a hold of it. That’s on him."
Green added:
"When he gets back in the box, take advantage of the at-bats you do get. Prove you deserve more at-bats," Green continued. "I think people get into different phases in their career at different points in time. He has all the talent that he possessed in ‘24 when he was hitting close to 30 home runs and didn’t start the season with the big league club. It’s all right there. It’s on him for that to come out. We certainly want to see it come out. It’s not going to be a perfectly laid path for him, though, when he does come back."
Given how straightforward Green often is and the way he challenges players, it wasn't a departure for him to speak that way about Vientos. But it was still notable.
After being activated, Vientos was pretty much the player he had been earlier in the season, as he hit .216/.268/.432 with two homers in 41 plate appearances over 14 games.
For all the promise Vientos showed in 2024, his last two seasons have been a disappointing slog. And this offseason feels like the time to move on.
