Zac Thornton may have done more for the Mets’ offseason plans than any headline-grabbing move could.
The rookie has turned into a real answer in the rotation conversation, and that matters because it gives the front office a built-in alternative to chasing a random free-agent starter. Thornton wasn’t exactly being penciled in as a major 2026 factor, but his rise has changed the shape of the discussion.
At 3-3 with a 2.78 ERA, Thornton hasn’t been overpowering - his 5.8 K/9 rate says as much - but he’s made his living by filling the zone. His 2.6 BB/9 shows the kind of strike-throwing that keeps him in games, and he’s found enough different ways to get outs to make himself hard to ignore. He’s not locked into a roster spot for next year yet, but he’s already giving the Mets a pretty clear answer about how to approach the back end of the rotation.
That answer is simple: there’s no need to force a big swing if Thornton keeps this up. He looks like a legitimate option for the fifth starter job, and the Mets could go into next season with one premium arm at the top and Thornton or another internal candidate filling the last spot.
That creates a real competition. A spring battle - or maybe even a summer one if CBA negotiations push things back - between Thornton, Jonah Tong and Jack Wenninger is already easy to picture.
The Mets could still look for an experienced arm from overseas or one available after being freed from his contract, ideally someone with minor league options. Whether that kind of tidy solution exists is another question, especially with David Stearns’ history of favoring quantity without enough attention to quality.
If the Mets do make a big splash, Tarik Skubal stands as the biggest free-agent starting pitcher. But landing him would likely shut down the spending. There’s still a bullpen that needs almost complete restructuring, and even if the final weeks produce strong performances from some arms, the expectation is that no more than two will make the Opening Day roster if everyone stays healthy.
Nolan McLean already gave the Mets a similar kind of internal win. His strong pre-rookie season in 2025 was enough to tell the team they didn’t need to add another starter that offseason, and there was never really a question about whether he’d make the club. The only real debate was whether he or Freddy Peralta would get the Opening Day assignment.
Thornton, though, is now in a different lane from the other Mets rookie starters who’ve debuted in recent years. He’s not just surviving; he’s producing.
The question isn’t whether he belongs right now. It’s whether there’s enough evidence to think he can become even more than this.
At the moment, there’s no reason to send him back down unless he gives the Mets one.

Mets Prospect Rankings Just Raised A Bigger Question About The Farm
MLB Pipelines latest update to the Mets top prospect list reflects how much the farm has shifted after recent trades and draft picks, and it gives a clearer picture of where the organization stands right now. One of the more notable changes is the rise of Cole Mathis, while Emilien Pitre has emerged as a player who could fit the utility role the club always seems to value. The update also underscores a lingering concern for the system: catching remains an area where the Mets still do not have an obvious answer waiting in the wings.
The trade that sent Huascar Brazoban elsewhere is part of that broader conversation, because the return brought back Zach Franklin and Gabe Davis and added more depth to a system that is still trying to strengthen its middle tiers. Even so, the rankings suggest the Mets are left with a familiar question about quality at the top versus volume throughout the rest of the farm. For a team that keeps looking for the next wave, the bigger issue may be whether the organization has enough impact talent developing fast enough to matter. [Read more 🡒]
Mets May Have Found A Corner Infield Answer They Need To Win
The Mets have spent plenty of time this season trying to piece together their corner-infield picture, and an offseason name has already surfaced that fits the kind of search they may need to keep doing. Teruaki Sato, the 2025 NPB Central League MVP, has been turning heads in Japan with strong offensive production, and his profile makes sense for a club looking for help at either first or third base.
Sato is the sort of player who can draw a wide market quickly, especially when a team is hunting for a bat that might stabilize a position for the long term. For the Mets, the appeal is obvious: a productive infielder with a track record that suggests he could translate into a meaningful upgrade, even if the competition for him is expected to be crowded.

Mets Face A Growing Jorge Polanco Decision They Can't Ignore
Jorge Polancos first season in New York has been shaped as much by the Achilles issue as by any hope the Mets had for him at first base. He returned in mid-July after the injury, but the club has not gotten the kind of steady offensive presence it needed from the bat in the middle of the lineup, and his role has already become a bigger organizational question than anyone wanted when the season began.
The Mets still have to sort out what comes next, both because of the contract commitment and because Polanco has not looked like a comfortable fit handling the everyday load at first. As the club thinks ahead to 2027, the most realistic path may be to prioritize his recovery and find a way to use him in a lighter role, with the infield and DH mix giving New York more flexibility than asking him to keep carrying the same responsibilities.
