Pirates' Quinn Priester: Beginning rehab assignment

Priester (lat) will begin a rehab assignment with Triple-A Indianapolis on Wednesday, Alex Stumpf of MLB.com reports.

Priester has been on the 15-day injured list since June 6, but he has been given the green light to test his injured lat in a competitive setting. The Pirates haven't specified how many rehab outings the 24-year-old will need, but it's likely he returns from the IL before the All-Star break.
