Twins outright righty Pryor to Triple-A Rochester

Club likely to add NRIs Boyer, Robinson to 40-man roster

Twins outright righty Pryor to Triple-A Rochester

The Twins outrighted right-handed pitcher Stephen Pryor to Triple-A Rochester on Sunday, leaving the club with 38 players on its 40-man roster.

Minnesota likely will use those open spots to add a pair of non-roster invitees, reliever Blaine Boyer and outfielder Shane Robinson.

The Twins acquired Pryor from the Mariners for Kendrys Morales last July, and he spent the rest of the season at Rochester, allowing two runs over 20 1/3 innings. Pryor appeared in 34 games for Seattle from 2012-14, producing a 2.81 ERA with 35 strikeouts and 16 walks over 32 innings. He pitched six innings for the Twins this spring, giving up one run on four hits, with one walk and one strikeout.

Boyer pitched 32 games for the Padres last year, his first Major League action since 2011. The 33-year-old righty has held the opposition to two runs, five hits and one walk over 10 2/3 Grapefruit League innings, with five strikeouts.

Boyer closes it out

Robinson went 0-for-3 in the Twins' 6-5 win over the Orioles on Sunday, dropping his spring average to .286 (12-for-42) with four doubles and four walks. Over parts of five seasons with the Cardinals, the right-handed batter hit .231/.303/.308 while spending time at all three outfield spots.
