Nationals Place Trevor Williams On Injured List With Elbow Sprain

The Nationals announced a series of roster moves this morning, headlined by their placement of right-hander Trevor Williams on the 15-day injured list due to a right elbow sprain. Right-hander Ryan Loutos was recalled to the MLB roster to replace Williams. In an additional move, Washington has activated catcher Keibert Ruiz from the 7-day concussion-related injured list and optioned catcher Drew Millas to Triple-A.

Williams, 33, has been part of the Nationals’ rotation all year but struggled badly with his results. The righty is sporting a 6.21 ERA across 17 starts and 82 2/3 innings this year. That’s the third-worst figure in baseball among pitchers with at least 80 innings of work this year. Brutal as the results have been, it’s perhaps worth noting that Williams has gotten quite unlucky according to the underlying metrics. His .347 BABIP allowed is nearly fifty points higher than his career mark, and a 61.6% strand rate suggests he’s been the victim of poor sequencing as well. Williams’s 4.08 FIP and 4.45 FIP paint him as a roughly average fifth starter based on his performance this year, despite the rough run prevention numbers.

In terms of strikeout and walk rate, Williams hasn’t been all that different than 2024. Last year saw him pitch to a dazzling 2.03 ERA in 66 2/3 innings, but his results then were much better than the metrics suggested they should have been. Taken together, Williams’s strong but abbreviated 2024 and his brutal first half this year paint a picture of a mid-to-back of the rotation arm: 30 starts, a 4.34 ERA, a 3.51 FIP, and a 4.23 SIERA. Perhaps there would’ve been a pitching-needy club or two who would have viewed Williams as a decent innings-eating arm to bet on for a low-cost flier this summer, but today’s injury news will throw a wrench into that possibility.

The exact details surrounding Williams’s injury are not yet known, but any injury involving a pitcher’s elbow is concerning and will typically be treated with an abundance of caution to avoid further damage. Williams figures to be out for several weeks at the very least and could miss much longer than that. A clearer timeline for his return to action figures to be available with time, but Mark Zuckerman of MASN reports that Williams himself suggested that the injury is “comparable” to the flexor strain that cost him more than three months last year. A similar timeline for his recovery this time around would likely put an end to his 2025…
