Twins purchased the contract of RHP Casey Fien from Triple-A Rochester.
He’ll take the roster spot of Nick Blackburn, who was demoted to the minors. Fien signed a minor league deal with the Twins over the winter and had a 4.30 ERA and 42/14 K/BB ratio over 46 innings at the Triple-A level. The 28-year-old right-hander hasn’t appeared in the big leagues since 2010 as a member of the division rival Tigers.
