Boshers was recalled Sunday from Triple-A Rochester, Brandon Warne of ZoneCoverage.com reports.
Boshers had thrown just 3.2 innings at Triple-A, allowing three earned runs. The 28-year-old has been a career minor-league journeyman, but appeared to turn things around in 2016 with improved control. Still, don't expect the Twins to count on him in high-leverage situations out of the bullpen.
