Naughton (elbow) is nearing throwing, Rhett Bollinger of MLB.com reports.
Naughton suffered a Grade 1 flexor pronator strain in late February and was originally given a 3-5 week recovery timetable, but he appears to be ahead of schedule given the favorable update. He isn't considered an option for the Opening Day roster, so he'll work with an eye on pitching at the Triple-A level upon his return.
