Will Warren started the most important game of the Yankees season so far, and that was fitting. He and other Yankees who have not pitched leverage innings for them this season will likely be doing so when their season is on the line in October. After they traded away relievers and did not replace them before the trade deadline, the Yankees will be relying on their ability to create an October bullpen weapon or two on the fly.
Warren, who threw seven shutout innings in Sunday’s win – a game that gave them the season series over the Red Sox and home-field advantage in the first round if the teams finish with the same record – will almost certainly be pitching out of the bullpen when the postseason schedule eliminates the need for a fifth starter. Sunday, he reminded the Yankees why he will be a valuable piece of their pitching staff moving forward, whatever role he holds.
“I felt like I feel like that every week,” Warren said after a masterpiece made more crucial by the fact that the Yankees bullpen was depleted by Saturday’s doubleheader. “Sometimes it doesn’t obviously play like that. But I’m confident every time I take the mound.”
Former rookie of the year Luis Gil will spend the next few weeks auditioning for a relief role after being called up for the first time in 2026 on Sunday. Clarke Schmidt, owner of a 3.82 career ERA, said Sunday that he felt good after his first rehab outing since Tommy John surgery in July of 2025 and should be built up enough to serve in relief when he returns.
If Ryan Weathers can somehow heal his elbow injury in time to pitch in the postseason, he probably would not have time to build back up to starting. He might have been in for a switch even if he were healthy: The Yankees always seemed likely to shift him to the bullpen in October anyway.
Joining them on the audition list are veterans Justin Topa and Michael Fulmer, acquired off the waiver wire after Fernando Cruz suffered an elbow injury that left the Yankees bullpen looking thin. Paul Blackburn has become nearly unhittable, which has helped the Yankees handle setup innings ahead of David Bednar. But if he lapses into mere mortality again – or if Brent Headrick starts showing the effects of making 20 more appearances in a season than he has ever made before -- they will have to get creative in leverage.
Options exist in the minor leagues, too. Yerry De Los Santos, optioned Sunday because the Yankees needed a fresh arm, has a 1.35 ERA in 15 big-league appearances this year. Aaron Boone said he expects De Los Santos to return to the major league roster before season’s end.

Angel Chivilli, who looked unhittable at times until suffering an elbow injury in early August, has resumed throwing. Boone said last week that Chivilli could “still be an option.” The Yankees recently signed veteran Eli Morgan to a minor league deal, and if he pitches well in Scranton, he might earn a tryout, too. But there are few sure things in that bunch – and no surer thing for a Yankees team struggling to score than close games down the stretch.
The Yankees have plenty of time to gain clarity. Ultimately, the eventual makeup of their postseason bullpen might become far more obvious than it seems right now. But those three current and former starters will have substantial influence over its October composition.
Warren has only made two career relief appearances, but he has a five-pitch arsenal he could winnow into his best three pitches, one of which is a fastball that sits in the mid-90s but has touched 97 and could reasonably be expected to sit nearer that number in short bursts. And he didn’t
Schmidt said he too plans to pare down his arsenal for bullpen duties – and that he thinks his stuff could grow livelier in shorter outings, as well.
“I would like to think [it would tick up], I would hope so,” Schmidt said. “I think obviously you pitch a little bit differently in that role. You can kind of let it eat a little bit.”
Schmidt, 30, said he hasn’t discussed the specifics of his bullpen role with Yankees management, though his understanding that it could resemble the multi-inning hybrid role Michael King served at times under Boone.
Gil, meanwhile, will still need to prove he deserves a bullpen start before the Yankees start to shape one for him. The righty did not make the Yankees rotation out of spring training and dealt with a shoulder injury until mid-August. He has not allowed a run in five Scranton appearances since returning. All five appearances have been for two innings or fewer.
“He seems healthy. He seems strong. The fastball seems like it’s in a good place: the profile seems good,” Boone said. “Encouraged with how he’s looking, how he’s bouncing back and everything.”
Exactly where the October innings will go will be dictated by what happens between now and late September, when the Yankees can test potential leverage options in games that, if their recent track record is any indication, will be close late. Then again, the Yankees offense scored 22 runs between Saturday night and Sunday. When it comes to solidifying a bullpen in flux during a pennant push, a few extra runs a night certainly wouldn’t hurt.
