Athletics' Aledmys Diaz: Starts running program

Diaz (calf) has begun a running program as part of his rehabilitation process, the Associated Press reports.

The veteran infielder opened the season on the 60-day injured list, so he's seemingly only in the nascent stages of his ramp-up process. Diaz could eventually require a rehab assignment of maximum length whenever he's deemed ready to test himself in game action, given how long he's been sidelined.
