The Rays waited out Juan Carlos Oviedo‘s rehab from Tommy John surgery in hopes that he would emerge as a valuable piece in their bullpen this season, but he was designated for assignment this afternoon in order to make way for Jeremy Hellickson‘s return from the minors.

After missing all of 2013, Oviedo has posted a 3.69 ERA and 26/16 K/BB ratio over 31 2/3 innings this season. The 32-year-old made himself expendable by allowing 10 runs over his last 15 appearances. He’s owed a little under $750,000 for the remainder of the season, so somebody could take a chance on him the rest of the way.
