A quick update on some of the Pirates’ pitchers recovering from injury:
— Charlie Morton pitched Thursday for Altoona, going four innings while allowing two hits (both home runs) and two runs (both earned) with one walk and one strikeout. Pittsburgh manager Clint Hurdle said Morton is on a five-day rotation with three more rehab starts scheduled and that his next start will be for Triple-A Indianapolis.
— Jeff Karstens is scheduled to make a rehab appearance Saturday for Altoona. Hurdle said the goal for this start is to see Karstens somewhere in the four innings, 65-pitch range.
— James McDonald is still in the early stages of rehabilitation. Hurdle said McDonald recently played flat-ground catch but is not yet throwing off a mound.
