Pirates' Colin Holderman: Begins rehab assignment

The Pirates sent Holderman (illness) to Triple-A Indianapolis on Friday to begin a rehab assignment.

A lengthy battle with a virus kept Holderman out of action for a significant amount of time during spring training, so he will head to Indianapolis in order to properly prepare for his regular-season debut. The 28-year-old righty will be eligible to return from the IL on April 9.
