The Royals released John Parrish, according to Bob Dutton of the Kansas City Star (via Twitter). The lefty has been sidelined with shoulder problems and last pitched on April 24th.
The Royals signed Parrish to a minor league deal in January and got six relatively productive innings out of the him. He struck out four and allowed as many hits in six innings, walking five. The 32-year-old has big league experience with the Orioles, Mariners and Blue Jays; until he joins his next franchise he's a free agent.
The move frees up a 40-man roster spot for Anthony Lerew, who has been recalled from Triple-A according to Daniel Paulling of The Kansas City Star.
