Mets select Zack Short, recall Tobias Myers in roster shuffle

The New York Mets announced the selection of infielder Zack Short's contract from the minors and the recall of right-hander Tobias Myers, completing a four-piece roster shuffle that also sent right-hander Dan Hammer to a designated-for-assignment designation and placed infielder Mark Vientos on the 10-day injured list with a right hand fracture.

What happened

The Mets announced all four moves together. Short's contract was selected from the minor-league side, adding him to the 40-man roster and the active roster in one step. Myers was recalled from the minors. On the corresponding side, Hammer was designated for assignment — a move MLB Trade Rumors had previously covered — and Vientos was placed on the 10-day injured list, the club citing a right hand fracture.

The 10-day injured list is the standard placement for position players; under general league rules, a player on the 10-day IL can later be transferred to the 60-day IL if the situation warrants, though no such transfer has been reported here.

Why it matters

Vientos' absence is the operational engine behind the rest of the moves. With a right hand fracture sidelining one of the club's infielders, the Mets needed a body who could play the position, and Short — arriving from the minors — fills that gap on the active roster. The Hammer DFA clears the corresponding 40-man space that Short's contract selection requires, which is the quiet bookkeeping that makes the visible move possible.

Short is an infielder, so his arrival maps directly onto the hole Vientos leaves. Myers' recall addresses the pitching side of the ledger, giving the Mets an additional arm as they head into a three-game home series against the Boston Red Sox.

What's the status on Vientos?

The club announced the 10-day IL placement with a right hand fracture as the listed reason. Beyond that designation, no timetable or additional detail has been reported. The 10-day IL sets a minimum absence, but a fracture's recovery arc is not something the announcement specifies, and MLB Trade Rumors offered no further detail on expected duration. That remains the central open question from this transaction cluster.

Where the club stands

The Mets carry a 74-88 record, a .457 winning percentage, and a position in the NL East that is 20 games back in the division. They have been eliminated from both the division race and the Wild Card race, and they enter this series on a one-game losing streak. In the Wild Card picture, they rank 10th, sitting 14.0 relative to the cut line — a number that, at this point in the calendar, is more archaeological than actionable.

A club eliminated from postseason contention still has to field a functional 26-man roster every day, and the Vientos injury created a gap that needed filling before the Red Sox arrived. The upcoming schedule has the Mets hosting Boston at Citi Field across three games: Friday features Nolan McLean against Sonny Gray, Saturday brings Freddy Peralta against Eduardo Rivera, and Sunday closes the series with Zac Thornton against Payton Tolle.

That rotation of names — and the fact that Myers was recalled specifically to bolster the roster heading into it — is the immediate operational context for these moves. The series is already set at the starter level; where Myers fits into the bullpen picture around those games is the next piece of information the club will reveal simply by playing.

For Hammer, the DFA opens a seven-day window in which the club must trade him, release him, or pass him through outright waivers. That clock is now running.

What we don't know yet

The Vientos timetable is the most consequential unknown. A right hand fracture is the diagnosis the club announced; what that means for his return — whether it resolves in weeks or stretches longer — has not been reported. The 10-day IL is a floor, not a ceiling.

Short's role once he arrives is also unspecified. The announcement establishes that he is an infielder whose contract has been selected; how the Mets deploy him across the Red Sox series and beyond is not something the club has detailed.

Hammer's fate is similarly unresolved. Designated for assignment, he now enters the transaction process that general league rules prescribe — trade, release, or waivers within seven days — but no outcome has been reported.

Myers' specific role, whether as a starter or in relief, has not been described in the announcement or in MLB Trade Rumors' coverage.

What to watch

The Vientos situation is the thread worth pulling. If the club provides any update on his recovery timeline, that will clarify how long Short is expected to hold down the infield and whether additional moves might follow. A fracture that resolves quickly looks different, roster-construction-wise, than one that stretches into August.

Hammer's DFA resolution — trade, release, or outright — will arrive within the week. That outcome is worth tracking for anyone monitoring the Mets' 40-man construction, even if the playoff math has long since been settled.

And Myers, back on the active roster, gets his first look in a Citi Field series against Boston. Short's debut, whenever it comes, will be the most visible consequence of a transaction cluster that started with a fractured hand and ended with four names moving in four different directions — which is, more or less, how the roster management calendar works when the standings have stopped being the point.
