Beimel, in his second stint with the Pirates, was a non-roster invitee to Bradenton this spring and began the regular season in Single-A due to left elbow inflammation. All told, he pitched three scoreless minor-league innings.
To make room on the 25- and 40-man rosters, the Pirates designated LHP Garrett Olson for assignment.
Beimel is a native of St. Marys, Pa., and attended Duquesne University in Pittsburgh. He is a veteran of 532 appearances, and sports a 23-31 career record.
