Billingsley would not speak with reporters, but manager Don Mattingly said, "Chad felt good. This is the first time he's thrown since he walked off."
That was Aug. 24, when Billingsley felt something give in his elbow while pitching against the Marlins at Dodger Stadium and on a six-game win streak.
He has since had two platelet-rich plasma injections to accelerate the healing process and four weeks of rest. Billingsley will essentially go through a Spring Training regimen to see if his elbow holds up. If not, he will have Tommy John reconstruction and miss the entire 2013 season.
