The Pirates have released left-handed pitcher Scott Olsen.
Olsen was signed by Pittsburgh this past winter.
"We believed we were not going to have a good opportunity for Scott and made this move to allow him to find a better situation," general manager Neal Huntington said.
Olsen, 27, signed a one-year contract in the offseason worth $550,000 with a club option for 2012.
He sustained a hamstring injury early in spring training this season in Bradenton and never fully recovered.
