Burnett has experienced a couple of setbacks in his quest to return from August elbow surgery and hasn't appeared in an official game since late May of last season. De La Rosa was delayed in Spring Training because of a strained right forearm and is now working his way back from tightness near his collar bone that Scioscia said "isn't anything that's going to impact long-term what he needs to do."
Asked which of the two is farther ahead in his rehab, Scioscia said, "At first, Dane was closer. Sean's making a lot of progress, but there's still some work to do with both of them, so it's tough to say who's really projecting closer. Dane still has the probability of coming a little quicker because he has more behind him than Sean."
