ANAHEIM -- Angels right-hander Kelvim Escobar said Wednesday that he suffered a setback in his return from right shoulder surgery and won't be ready to come back until June instead of May, as was thought.
Escobar, who made a pair of impressive rehab starts before getting shut down with an inflamed right shoulder, is currently only throwing long toss and won't be back throwing off a mound until this weekend, when he's scheduled to throw a bullpen session.
"If I come back as a starter, it's going to take a while," said Escobar, who threw from 150 feet on Tuesday. "I have to build up to 100 pitches, so that will take four or five games, which is at least a month. And that takes us to June."
Escobar will extend to throwing from 170 feet, but he said he'll be cautious this time because he said he rushed himself too much in Spring Training.
"I think I did too much, too soon," Escobar said. "I was anxious and happy about how I felt. When I saw [John] Lackey and [Ervin] Santana go down, I think I was trying come back quicker than I needed."
Escobar last started on April 3 against the Padres in an exhibition game at PETCO Park and was reactivated again only last week. But Angels manager Mike Scioscia isn't worried about Escobar's progress.
"He feels very good, but it's going to be a process with him," Scioscia said. "We need to step back before we push forward because it will take time to get to 100 pitches. We had to be prepared in case of a setback so we'll take it from there."
