Merrill Kelly Injury: Set for another bullpen

Kelly (back) threw a successful live batting practice session Sunday and will throw another one this week before potentially pitching in a Cactus League game, Steve Gilbert of MLB.com reports.

The veteran right-hander is working his way back from a bout of mid-back tightness, which prevented him from building up normally early in camp. Kelly is now ramping up his throwing sessions and could soon be cleared for game action. He won't be ready for the opening series of the season, but manager Torey Lovullo previously indicated that could still avoid a stint on the injured list to begin the campaign.
