Diamondbacks' Alek Thomas: Running bases

Thomas (hamstring) ran the bases with cleats Saturday, Jesse Friedman of GoPHNX.com reports.

Thomas endured a setback during the recovery from a left hamstring strain in late May, and after being shut down from running, he resumed running the bases Saturday. He's expected to begin a rehab assignment next week, but manager Torey Lovullo said Wednesday that Thomas won't need many games before being activated considering how many at-bats he's taken while on the injured list.
