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.

More to come.
