Zack Greinke (calf) threw another bullpen session on Thursday morning in Dodgers camp. Greinke made 25 throws, mixing in breaking balls, and reported no physical discomfort. He should face live hitters next in a simulated setting and could then return to Cactus League games. Greinke is likely a candidate to start March 30 in San Diego -- the Dodgers' first game back from their trip to Sydney, Australia.
