Waldron (forearm) could take on a bullpen role when he returns from the 15-day injured list, MLB.com reports.
Waldron landed on the IL last Friday due to a right brachialis muscle injury. He had initially been slated to be designated for assignment, as Waldron lost hold of his spot in the rotation after Lucas Giolito was cleared to make his team debut. If Waldron remains with the club after he gets healthy, he'll likely be asked to work out of the bullpen, barring injuries to other starters reopening a spot in the rotation. Over six appearances (three starts) with San Diego so far in 2026, Waldron has posted a 8.49 ERA and 1.71 WHIP over 23.1 innings.
