The Twins have outrighted right-hander Stephen Pryor to Triple-A Rochester, tweets Phil Miller of the Minneapolis Star Tribune. The Twins’ 40-man roster now stands at 38, which, Miller notes, will allow the team to add a pair of non-roster invitees, presumably reliever Blaine Boyer and outfielder Shane Robinson.
The Twins acquired the 25-year-old from the Mariners last July in exchange for Kendrys Morales. Pryor, who underwent surgery to repair his latissimus dorsi muscle in 2013, excelled at Triple-A for the Twins after the trade recording a 0.89 ERA and 9.7 K/9 in 14 relief appearances covering 20 1/3 innings, but demonstrated a lack of command as evidenced by his 7.1 BB/9 rate.
