Diamondbacks' Merrill Kelly: Set to throw live BP

Kelly (back) is slated to throw live batting practice Sunday, Alex Weiner of ArizonaSports.com reports.

Kelly threw a bullpen session Thursday and came away from the session feeling good. He'll take the next step in his recovery Sunday by facing batters. The 37-year-old threw roughly 30 pitches in the bullpen session and utilized his entire arsenal.
