Pivetta (forearm) has advanced to playing long toss and could soon begin throwing off a mound, MLB.com reports.
Pivetta has been sidelined by a right flexor strain since mid-April. The right-handed hurler began a throwing program in late May, but he's yet to start up mound work. With that big step potentially looming, Pivetta appears to be making tangible progress in his recovery. Nonetheless, he's not expected to return to San Diego's rotation until sometime after the All-Star break.
