Pirates' Jared Triolo: Starting rehab assignment

Triolo (knee) will begin a rehab assignment with Single-A Bradenton on Friday, Kevin Gorman of TribLive.com reports.

Analysis:

Triolo has been sidelined for nearly three weeks with a knee issue, but he's ready to test things out in a game setting. The infielder could be ready to return at some point next week and will be in the mix for starts at third base when he is activated.
