Dodgers starting pitcher Zack Greinke (elbow) played catch for the second consecutive day Saturday and could advance to a bullpen session by next week, MLB.com reports.
Greinke received a platelet-rich plasma injection in his right elbow last Monday in the hope of eliminating some lingering irritation.
Los Angeles manager Don Mattingly remains uncertain when the team's newest ace will return to game action as he looks to preserve his health for opening day.
"[Greinke is] good. It sounds like he's encouraged after throwing," Mattingly said. "He called it a good day. If everything is good [Sunday], he can have a light bullpen. I'm not throwing a date out [for a game]."
