According to Corey Brock of MLB.com, the Padres have designated RHP Walter Silva for assignment. Infielder Craig Stansberry has been recalled to replace Silva on the roster.
The Padres had inked the 32-year-old Silva to a minor league deal in February out of the Mexican Winter League. Silva started six games for the Padres and put up an ugly 8.76 ERA and 11/15 K/BB ratio in 24.2 innings. Brock notes the Padres don't have to make up Silva's rotation spot until Saturday, so it's unclear who will replace him for now.
