Mets place Robert Stock and Daniel Duarte on IL, both done for the season

What happened

MLB.com, per Bill Ladson, reported that Mets right-handers Robert Stock and Daniel Duarte have both been placed on the injured list and are done for the 2026 season. The moves close out the year for two members of a bullpen that has been reshuffled repeatedly as September has worn on.

Why it matters

For a club already eliminated from both the division race and the Wild Card race, the practical stakes of any single roster move are modest. But the simultaneous loss of two right-handed relievers still has operational weight: the Mets need arms to finish out a schedule that includes a home series against the Philadelphia Phillies beginning Friday, and the bullpen depth behind whatever starters take the ball has to come from somewhere.

September rosters expand to 28 players under current league rules, which gives clubs more flexibility to carry additional pitchers than they would have in August. That flexibility matters more when two arms are removed from the equation at once. The Mets will need to fill those spots from whatever is available on the 40-man roster or through other roster construction decisions — none of which have been reported as of this writing.

The timing also lands in the middle of a stretch of notable bullpen turbulence. A week removed from the Mets outrighting right-hander Chris Devenski to Triple-A Syracuse after he cleared waivers, and with the club having claimed infielder Christian Cairo off waivers from the Phillies just days ago, the roster has been in near-constant motion. The Stock and Duarte placements add two more entries to a September ledger that has been anything but quiet.

Is Edwin Díaz available to help cover the load?

That question is genuinely open. Per a Posterior Wire report from earlier this week, Edwin Díaz was expected to return from his rehab assignment on Friday after completing his fifth rehab outing — though his October role was described as not guaranteed. Whether Díaz's return changes the calculus around the bullpen's available depth is something the club has not addressed publicly in the material available here. What is clear is that the Mets are navigating the final weeks of the season with a relief corps that looks different than it did even a few days ago.

Adding a layer of uncertainty: Shane Baz exited a start earlier this week after taking a comebacker off his elbow, per a Posterior Wire report, raising questions about his own availability going forward. The Mets' pitching situation, in other words, is being shaped by multiple moving parts simultaneously, and the Stock and Duarte placements are the latest entries in that ledger.

The numbers

The Mets enter Friday at 69-83 (.454), sitting fifth in the NL East, 19.5 games behind the division leader. In the Wild Card picture, they rank 10th, 14.5 games relative to the cut line. New York has lost four straight. The season's destination has been settled for some time — the club is eliminated from both the division and Wild Card races — but there are games left to play, and the roster still has to be staffed accordingly.

Where the club stands

The Mets open a home series against the Philadelphia Phillies at Citi Field on Friday, with Zac Thornton listed as the probable starter against a Philadelphia arm to be determined. Christian Scott is slated for Saturday's game, also against a Phillies starter yet to be named. Sunday's series finale has Jonah Tong projected to face Cristopher Sánchez.

That the Phillies are the opponent is its own small irony: the Mets claimed Christian Cairo off waivers from Philadelphia just days ago, and now they welcome the same club to Citi Field while sorting through a bullpen that just lost two arms. Baseball's scheduling department does not consult the transaction wire.

What we don't know yet

The material does not specify the nature of the injuries that placed Stock and Duarte on the IL, nor does it indicate which IL designation — 15-day or 60-day — applies to either pitcher. The distinction matters for 40-man roster accounting: a 60-day IL placement removes a player from the 40-man count, creating a roster spot, while a 15-day placement does not. That detail has not been reported here.

It is also not reported whether the club has identified specific replacements for the two roster spots created by these moves, or whether any corresponding transactions are forthcoming. The Devenski outright to Syracuse earlier this week removed one right-handed option from the 40-man picture, which narrows the pool of readily available arms — though the full scope of what is available internally has not been detailed in the material at hand.

Díaz's status, as noted, remains a watch item. His return from rehab was expected Friday per earlier reporting, but his role and availability beyond that point carry uncertainty that has not been resolved publicly.

What to watch

The most immediate question is what the Mets do to fill the roster spots left by Stock and Duarte. Any corresponding moves — whether a call-up from Syracuse, a claim, or another transaction — would clarify the shape of the bullpen heading into the final days of the regular season.

Díaz's Friday return, if it proceeds as reported, will be worth monitoring both for his performance and for any club statement about how he fits into the remaining schedule. A bullpen that has seen this much turnover in a single week will need some stabilizing presence, and Díaz, whatever his October role turns out to be, is the highest-profile arm in that mix.

The Phillies series also offers a natural measuring stick. Philadelphia is a club still playing meaningful games, which means the Mets' pitching staff — starters and relievers alike — will face a lineup with something to play for. How the club manages its available arms across three games, with Thornton, Scott, and Tong lined up in succession, will tell something about where things stand as the 2026 season winds toward its close.

Stock and Duarte are done. The calendar has a few weeks left. The Mets are filling in the blanks.
