PITTSBURGH — The Pittsburgh Pirates placed starting pitchers A.J. Burnett and Charlie Morton on the 15-day disabled list Wednesday on the eve of the team’s season opener against Philadelphia.

Burnett is dealing with a fractured right orbital bone suffered during a bunting drill. He had surgery on March 2 and was expected to miss two to three months but appears to be ahead of schedule. He is eligible to come off the DL on April 10 and manager Clint Hurdle said Wednesday that Burnett will start for the Class A Bradenton Marauders on Friday.

Morton is still recovering from offseason hip surgery. He is eligible to come off the DL on April 13.
