The Pirates announced a series of roster moves this evening. Starter Trevor Williams is going on the 10-day injured list with a right side strain, creating a need for pitching reinforcements.
Righty Clay Holmes was recalled. He’ll join Geoff Hartlieb in ascending to the active roster. With a need for one additional active roster spot and one additional 40-man spot, the Bucs optioned righty Richard Rodriguez and outrighted catcher Jacob Stallings (who had been on the IL with a neck injury).
