Pittsburgh recalled Sanders from Triple-A Indianapolis on Saturday.
Sanders had a very brief stint with the big-league club in mid-April, getting into one game and allowing four runs over two-thirds of an inning. His call back to the majors Saturday corresponds with starter Braxton Ashcraft (personal) being placed on the bereavement/family medical emergency list. Sanders could be in for another short stint with the Pirates if Ashcraft isn't out beyond the seven-day maximum.
