Jared Hughes got the save Sunday to give Iglesias an extra day to rest, MLB.com's Mark Sheldon reports.
Iglesias had pitched on three consecutive days earlier in the week (Wednesday-Friday), picking up a loss on the third of those days. There doesn't appear to be an injury right now, though Iglesias last month had a trip to the DL with a biceps injury on his non-throwing arm, so it'll bear watching to see if there's any sort of recurrence.
