It's the first promotion of the season for the 23-year-old Yorke. He first reached the majors as a September call-up late last season. He hit .216 with a pair of home runs in 11 games. Pittsburgh optioned him back to Triple-A at the end of Spring Training. Yorke has spent the entire season in Indianapolis, where he has been on the active roster aside from a week on the injured list with a sore shoulder in the middle of April.
