The Washington Nationals designated Trevor Williams for assignment and activated Matt Waldron in the corresponding roster move, per Ben Raby of MLB.com.

The move

Williams exits the active roster via the DFA route, opening a spot for Waldron, who was claimed off waivers from the Blue Jays just days ago. That waiver claim — Waldron's second in under a month — now translates into an active roster slot.

Waldron's path here

Waldron's arrival in Washington was already a minor subplot worth tracking: the knuckleballer changed organizations twice via waivers in a short stretch before the Nationals claimed him from Toronto. His activation this quickly suggests the club had a specific role in mind when they made the claim.

What we don't know yet

What happens to Williams from here is unresolved — he can be traded, released, or claimed by another club during the DFA window. No timetable or destination has been reported.

The Nationals have been navigating a thin roster in recent days, with CJ Abrams working back from a sprained ankle and the club described as shorthanded heading into the weekend. Waldron's activation adds at least one arm to a staff that has been shuffling pieces with some regularity.
