Diamondbacks' Ketel Marte: Begins running

Marte (hamstring) has begun a running program, MLB.com reports.

Marte began swinging a bat a week ago and has moved to the next step in his recovery. There's still no word of when the second baseman can begin a rehab assignment. The Diamondbacks are getting by with a combination of Tim Tawa and Garrett Hampson at the keystone.
