The Twins designated Boushley for assignment Sunday.
Boushley has now been cast off the Twins' 40-man roster on two occasions, this time to make room on the active roster for utility man Michael Helman, whose contract was selected from Triple-A St. Paul on Sunday. The Twins are hopeful that Boushley will go unclaimed off waivers and remain in the organization as pitching depth at St. Paul. Over 22 starts at Triple-A this season, Boushley has turned in a 4.97 ERA, 1.30 WHIP and 94:20 K:BB across 116 innings.
