Worley has been on the 15-day disabled list since May 12 because of inflammation in his right elbow. He has made 70 throws from up to 120 feet the last couple days, and said he has felt no pain or discomfort in his elbow.
"I haven't felt anything," Worley said. "The inflammation has gone down. It's made it to where I'm not really feeling the bone chip right now. Will it come back? I don't know. If it does ... I don't have a choice."
Asked if he feels extra pressure to return following Halladay's injury, Worley said, "It's tough. I don't know exactly what's going on there right now. But I'm trying to get back as fast as I can anyway. I don't want to say there's more pressure, but I definitely want to be back ASAP. Especially now with that going on."
