The Twins made a couple of roster moves following Thursday's 9-3 loss to the Blue Jays. Catcher Chris Herrmann and right-handed reliever A.J. Achter have been recalled from Triple-A Rochester.
Herrmann was up earlier with the team, going 10 for 64 with a home run and eight RBI in 25 games as the back-up catcher.
Achter will be looking to make his season debut for the Twins. He did make seven appearances in 2014, posting a 3.27 ERA in 11 innings of relief. At Triple-A this year, he is 4-2 with a 2.82 ERA and 14 saves in 40 appearances for the Red Wings.
In corresponding moves, right-hander Tyler Duffey was optioned to the minors and catcher Eric Fryer was designated for assignment, according to MLB.com.
Duffey endured a horrific MLB debut in his start against the Blue Jays on Wednesday. Meanwhile, Fryer has just three hits in 18 at-bats this season.
