Boshers signed a minor league contract with the Twins Tuesday, Rhett Bollinger of MLB.com reports.
Boshers signed a minor league contract with the Rockies last December, but was released soon after spring training begun. The left-hander last pitched in an independent league, posting a 1.00 ERA, 0.98 WHIP, and 11.8 K/9 in 54.0 innings pitched. He'll likely serve as organizational depth for the Twins organization.
