PITTSBURGH (AP) — The Pittsburgh Pirates have designated pitcher Trevor Williams and utility player José Osuna for assignment. The team made the moves to create room on the 40-man roster for infield prospect Rodolfo Castro and starting pitching prospect Max Kranick. The 28-year-old Williams spent five seasons with the Pirates, the last four as a member of the starting rotation. Williams went 31-37 with a 4.43 ERA in 106 career appearances in Pittsburgh but struggled in each of the last two seasons. Osuna hit .241 in four seasons with the Pirates while bouncing around defensively.
