Nationals right-hander Trevor Williams told members of the media today that he has a partial tear of his ulnar collateral ligament and will undergo surgery. He is expecting it to be internal brace surgery, though a full Tommy John procedure is still a possibility. He will therefore miss the remainder of this season and possibly all of 2026 as well. He’s already on the 60-day injured list. Spencer Nusbaum of The Washington Post was among those to pass the news along.
Williams, 33, made his most recent start on Wednesday of last week. The first game of a doubleheader against the Tigers, Williams had a less-than-ideal experience. He struggled in the top of the first but, with a long day ahead, the Nats left him out there to take a beating. Pitchers usually aren’t allowed to throw more than 3o to 40 pitches in a single inning but the Nats let Williams throw 54 in that frame, as he eventually got out of it with six runs having scored. He tossed two more innings after that.
Two days later, he was placed on the 15-day IL with an elbow sprain. Yesterday, he was transferred to the 60-day IL, which indicated the Nats didn’t expect him back for a few months. With the news of this surgery, he’ll be out much longer than that. The timelines for an internal brace procedure can be a bit shorter than with a full Tommy John, though it’s still usually about a year.
Williams has been part of Washington’s rotation since 2023. He signed a two-year, $13MM deal ahead of that 2023 season. The first campaign in Washington didn’t go especially well, as he posted a 5.55 earned run average over his 31 starts.
Last year, he showed significant improvement, though in a smaller sample size. He missed a few months with a flexor strain, limiting him to just 13 starts, but with a 2.03 ERA. There was surely some good luck in there, as his .267 batting average on balls in play and 80.2% strand rate were both to the fortunate side. Part of the reason he was able to strand so many runners is that only 4.2% of his fly balls left the yard, a massive drop from his 17% rate in 2023. But on the other hand, his 22.7% strikeout rate, 6.9% walk rate and 45.4% ground ball rate were all strong figures. His 2.79 FIP and 3.96 SIERA suggested he could post good numbers even with some regression in the luck department.
The Nats decided to bring him back to serve as a veteran back-end guy, an understandable move for a rebuilding club with lots of inexperienced starters. They gave him another two-year deal, with the $14MM guarantee amounting to a slight pay bump compared to his prior deal. Unfortunately, his luck turned far in the other direction this year. In 17 starts, he posted a 6.21 ERA here in 2025. His strikeout rate dropped to 17.4% and his grounder rate to 33%, but he still only walked 5.6% of opponents. His .347 BABIP and 61.6% strand rate both swung far to the unlucky side. His 4.08 FIP and 4.46 SIERA suggested some correction over the rest of the season may have been likely but that won’t happen now.
Williams will spend the rest of this year on the shelf and will start next year on the IL as well. Depending on his surgery and rehab, he could work his way into the mix during the 2026 season. Whether there’s a rotation spot for him there will depend upon what the Nats do this winter.
For now, they have a rotation consisting of MacKenzie Gore, Michael Soroka, Mitchell Parker, Jake Irvin and Shinnosuke Ogasawara. Soroka is on a one-year deal and likely to be dealt this month. Gore has been the subject of some trade speculation since the Nats are struggling to come out of their rebuild and he’s only controlled for two more seasons after this one, but there hasn’t been any real suggestion the Nats want to make such a move. Parker and Irvin are serviceable back-end guys. Ogasawara only has one major league start so far, which didn’t go especially well.
Josiah Gray had UCL surgery last summer and could perhaps be back in the mix later this year. Cade Cavalli is in Triple-A and could be back in the majors at some point. Prospects like Travis Sykora or Jarlin Susana could get into the mix down the line but both are currently injured and neither has reached the Triple-A level yet.
If the Nats want to accelerate the end of their rebuild, spending some money to bolster this rotation group would be a sensible plan for this winter. However, the future is currently murky, with manager Dave Martinez and president of baseball operations Mike Rizzo having just been fired a few days ago.
