Montas (ribs) started throwing Saturday for the first time since his pre-camp surgery, Ken Gurnick of MLB.com reports.

That's the first step of what is likely to be a long rehab for Montas, who isn't eligible to come off the 60-day DL until June 2. He's likely to land in the bullpen when he returns, but the Dodgers' rotation depth has already taken enough injuries to consider the possibility that the team might need to try him out as a starter.
