2 Mets Opening Day DH candidates already on the roster, 3 they could sign in free agency

Who’ll be the New York Mets designated hitter when the 2025 season begins? A sentence fans as recently as 2019 would have vomited over reading (our grandkids will never believe pitchers used to hit), the reality is the DH has become a necessity for all National League ball clubs.

The Mets went with J.D. Martinez in 2024. Strictly a designated hitter at this stage of his career, this was always the biggest complaint about him coming to the Mets in the first place. It’s limiting when he isn’t effective. For the last few weeks of the season, he offered very little.

Whoever the Mets name as their Opening Day DH could change. Someone with a little more flexibility to defend—even if not too well—should be the primary selection. Two are already on the roster. Three others are free agents.

1) DH already on the roster: Mark Vientos

Mark Vientos remains a natural DH, maybe more so than even before his breakout 2024 campaign. At least now we can feel confident in his ability to actually hit at the major league level. His defensive shortcomings this past season can’t be ignored. While he wasn’t an incredible butcher with only 5 errors and some positive defensive metrics, we could all tell by watching him enough that there is a cap on how well he can play third base.

The Mets have a lot of directions they can go with Vientos. A move over to first base in case Pete Alonso leaves in free agency is one of the most discussed. Because they do have some internal candidates for third base, handing him some regular appearances as the DH could make sense, too. 

Vientos won’t toss his glove into the trash and strictly hit for the Mets. Rotating him at third base, DH, and maybe even at first base regardless of what happens with Alonso seems destined. Along with plenty of DH opportunities for him, a teammate of his might be more apt to receive even more.

2) DH already on the roster: Starling Marte

Starling Marte won a Gold Glove back in the day with the Pittsburgh Pirates. Today, he’s much less of a reliable outfielder for the Mets. He calls right field home which is a bit strange because when the Mets first signed him ahead of the 2022 season there was plenty of discussion about him playing center field over Brandon Nimmo. Those were good times.

Marte’s defensive decline has mirrored his health. He finished the season with a -8 Outs Above Average, a statistic which has become a must to view to measure every defensive player. His range is fading quickly. Despite still having good speed on the bases, he looks lost as an outfielder far too often.

Marte remains a player many Mets fans would like to see the team dump. It’s just not realistic. He’s an overpaid singles hitter they’ll try to milk one final season out of. For sure an unsatisfying selection to be the primary DH for the Mets in 2025, it does at least save the Mets from having to run him out into right field.

Could less time on his feet actually help Marte stay healthy and produce more at the plate? We can already scratch him from a couple of games in 2025. The Mets handled him carefully when they could this past season with playing time. With an open DH spot, they’ll have another way to utilize him in the final year of his contract.

1) DH the Mets could sign: Jesse Winker

Something close to yet not exactly mimicking a DH platoon between Marte and Jesse Winker is one direction the Mets could go. When Marte first returned from the IL, the two were sharing right field duties regularly. Then came Martinez’s September slump and both began to play a whole lot more. Winker did begin to sit a little bit more as he was also struggling through September.

Any fan whose adrenaline has yet to run out is ready to see Winker run into a wall for this ball club. He no doubt brought the kind of fun energy all fans come to adore. The downside is his defense wasn’t great. Combined with his Washington Nationals totals, he had an Outs Above Average of -11. Only six players had a worse number.

Winker belongs as a DH and only out of necessity did the Mets plug him into the corner outfield often. A better or at least more familiar left fielder, the trouble the Mets ran into was a declining outfielder playing somewhere he hadn’t often enough.

Sharing a roster with Marte made sense as the options for the Mets were limited at the trade deadline. Bringing him back means one of the two will always be out in right field. It’s okay if defense isn’t a priority. In fact, it might just help get the most out of both.

3) Joc Pederson

Consider this mention as one to come in after the polls have already closed. Joc Pederson decided to opt out of his deal with the Arizona Diamondbacks. Coming off of a productive season as their DH used mostly against right-handed pitchers, he's a good match to come to the Mets to take on the same exact role.

The exhaustion of a DH platoon created by the 2022 Daniel Vogelbach and Darin Ruf duo might be too fresh in some minds to think about this too positively. The realistic situation for the Mets, however, seems to include some sort of part-time DH with sprinkles of players like Starling Marte in there as well.

Pederson should be viewed as a Jesse Winker alternative, maybe even an upgrade. He has been a far more consistent hitter in his career. If used properly, Pederson's end of season numbers could end up looking spectacular.

Last year he hit .275/.393/.515 with 23 home runs in 449 trips to the plate. The Diamondbacks protected him as much as they could from facing lefties. He never saw an inning in the field on defense.

Imperfect because of his limitations, he does fill a role the Mets desired to have on the 2024 roster. What's more, the guy has personality. We saw how that can energize a clubhouse. Just don't trust him to stay within the boundaries in fantasy football.
