Merrill Kelly Injury: Feels fine after bullpen

Kelly (back) threw a bullpen session Thursday and said he felt fine afterwards, Alex Weiner of Arizona Sports reports.

Kelly unleashed his entire arsenal during the session, throwing close to 30 pitches. "I got a chance to speak with him directly after the bullpen, and he said he feels really good," Arizona manager Torey Lovullo said. The Diamondbacks have yet to determine the next steps for the right-hander, but the fact that Kelly was able to return to the mound this early in spring training bodes well for his availability for the regular season.
