Mets Roster Shuffle May Be Just The Start Of Bigger Changes

The Mets shake up their roster with key recalls and designations, signaling significant changes on the horizon.

The Mets shuffled their pitching staff and cleared a roster spot on Tuesday, recalling Robert Stock and Bryce Conley while designating Kevin Herget and MJ Melendez for assignment. Jonathan Pintaro was also optioned back to Triple-A Syracuse.

Stock gets the call ahead of his start today for the Mets. The 36-year-old right-hander last appeared in the majors with the Red Sox last season and also logged two outings for New York in 2021.

He has pitched for four big league organizations, spent time in the KBO, and has spent years grinding through the minors. When the Mets signed him this past offseason, Stock put his own journey into words on Twitter:

“I’m 36 years old and have had extremely limited MLB success. And yet MLB teams continue to give me chances.

Why? Because I continually find new ways to improve.

Newest trick for 2026 - the knucklecurve.”

Conley, 31, is the other fresh arm in the mix, and he’s still waiting on his first major league appearance. Drafted by the Athletics out of Georgia State in 2017, he’s been in pro ball ever since. With Stock and Conley both arriving on the same day, the Mets ended up with one of the more unusual and older pairs of recalled pitchers in recent memory.

Herget’s stint could be brief after he tossed a scoreless inning in yesterday’s game to open his 2026 season. He’s not new to the Mets, either, and now the club will wait to see whether he gets through waivers.

Pintaro had seven appearances for the Mets across the 2025 and 2026 seasons, including a two-inning, no-hit outing yesterday against the Marlins before being sent down.

Melendez, meanwhile, had served as a useful depth addition in the spring and got early playing time before A.J. Ewing took over the everyday job. In 144 plate appearances, he hit .192/.315/.350 with 10 extra-base hits.

Mets Just Got A Harsh Reality Check On Holmes And Peralta

The market for pitching just got another reminder of how hard it is to cash in at the deadline, and the Mets are watching closely. With New York trying to line up meaningful returns for Clay Holmes and Freddy Peralta, the recent Tarik Skubal trade to the Dodgers offered a useful comparison point for how clubs are valuing arms and prospects right now.

For the Mets, the lesson is less about one deal than about what it says for their own talks. They can ask for premium talent in return, but the threshold for landing a top prospect is steep, and that reality shapes everything from who they dangle to how long they can hold out. If they want the kind of impact package they have in mind, they may have to navigate a market that is already signaling just how limited the pool really is. [Read more 🡒]

Kodai Senga Just Gave The Mets A Tough Deadline Decision

Kodai Senga has become one of the more interesting names hanging over the Mets as the trade deadline approaches, and not just because of the way this season has gone. The right-hander has struggled through an 0-8 start with an 8.66 ERA, while New York is widely expected to move several veterans before the deadline and reshape the roster around what comes next.

San Diego has already inquired about Sengas availability, adding another layer to a decision the Mets have to weigh carefully. Even with the rough numbers attached to this year, Senga is not a simple rental piece, and any talks would have to account for the fact that he remains part of the clubs plans beyond this season, which makes the price and timing of a deal far less straightforward.

Mets Trade Leverage Just Changed For Clay Holmes And Freddy Peralta

Tarik Skubal landing with the Dodgers has shifted the starting-pitching market in a hurry, and the ripple effects reach all the way back to Queens. With one of the biggest arms moved, demand for available starters has only intensified, putting extra attention on Mets pitchers Clay Holmes and Freddy Peralta as the deadline approaches. New York is in position to benefit if other clubs get more aggressive, especially with a limited supply of impact arms available.

Holmes is working his way back from an injury and is scheduled for a rehab start, while Peralta was recently pulled from a start as teams looked to protect his health amid the trade buzz. Both are expected to move before the deadline, and the Mets are clearly in no rush to settle for a modest return. The market just got a little louder, and that could matter a lot for how the next few days unfold. [Read more 🡒]
