The Pittsburgh Pirates activated right-hander Jeff Karstens from the disabled list and optioned reliever Bryan Morris to Triple-A Indianapolis.
Karstens will make his first start for Pittsburgh tonight since April 17 when he exited after just one inning. He was placed on the 15-day disabled list the next day with right shoulder inflammation. He had his rehab pushed back due a groin injury as well.
