A poor start Friday has Twins right-hander Trevor May headed back to the bullpen as Tyler Duffey has been rewarded with another chance to start, per ESPN.
Duffey performed very well Saturday night against Cleveland after a miserable major league debut.
The team has also announced that fellow pitcher Michael Tonkin, who was recalled Friday, has been optioned to Triple-A Rochester.
May opened the year in the rotation, but his start Friday was his first since July 1.
