Chad Billingsley continues to make progress from a partially torn ulnar collateral ligament in his right (throwing) elbow.

The pitcher said Wednesday that he continues to throw from flat ground on back-to-back days, followed by one day of rest. He’s now able to make “about 35” throws from up to 60 feet, and is on track to throw off a mound in “a couple weeks.”

It was initially feared that Billingsley might have to undergo Tommy John surgery,which would force him to miss all of the 2013 season. But as long as he continues to throw without pain, that seems less and less likely.
