Chris Heisey (hamstring) is slated to be activated from the disabled list on Friday. Heisey will begin a short rehab assignment with Double-A Pensacola on Monday. "I'm feeling great, rehab is going well," Heisey said on Saturday. "The training staff has done a great job and walked me through it. I'd never hurt my hamstring before, it's a new thing for me. Feeling really good now."
