Billingsley, who had been slated to start, has pain in his right elbow. The Los Angeles Dodgers have placed Chad Billingsley on the 15-day disabled list for pain in his troublesome right elbow six days after the right-hander's second start of the season. Manager Don Mattingly said the Dodgers expect to learn more about the severity of Billingsley's injury after he has an MRI on his elbow. It got him two starts into this season, but Billingsley said Sunday he didn't rebound well from his most recent start Monday, when he allowed three runs in six innings to the Padres. Billingsley's injury could be the worst of the bunch, as the club has held its collective breath ever since he missed the final two months of the 2012 season with a partially torn elbow ligament, the kind of injury that usually requires Tommy John surgery and a year on the sidelines to fix. The Dodgers have gone from a surplus of starting pitching to a deficit in a span of 10 days. The Dodgers previously had traded starter Aaron Harang to Colorado on April 6 when it became apparent there wasn't a spot for him in the rotation.
