CHICAGO -- Right-hander Charlie Morton is set to take another step toward his eventual return to the Pirates' rotation.
Morton, placed on the disabled list at the end of Spring Training, will begin a Minor League rehab assignment on Saturday, manager Clint Hurdle said Tuesday.
Morton is slated to throw either seven innings or 90 pitches for Class A Advanced Bradenton in Port St. Lucie, Fla.
It will be Morton's first competitive game outside of extended spring action since an April 4 exhibition in Philadelphia in which he walked five batters and threw two wild pitches in 1 2/3 innings.
