Pryor was optioned to Triple-A Rochester. Pryor made five appearances this spring, allowing one run on four hits in six innings with one walk and one strikeout. He lost much of 2013 to shoulder issues and eventually underwent surgery to repair a torn lat, which caused his 2014 season to be delayed until July. He struggled initially last year (4.65 ERA) before finding his form after being traded to the Twins (0.89 ERA and 22 strikeouts in 20.1 innings at Triple-A, but with 16 walks). The Twins likely feel he needs more time in the minors to get back to full speed.
