Adalberto Mejia, acquired by the Twins from the Giants in a July 28 trade for Eduardo Nunez, was recalled from Triple-A Rochester, where he was 1-2 with a 4.66 ERA in three starts.
Mejia was scheduled to start Saturday for the Red Wings, but instead went to the Minnesota bullpen.
Mejia made his big league debut, giving up two runs on five hits, a walk and a sacrifice fly in 2 1-3 innings. Kenny Vargas, who hit .259 in 25 games, was optioned to Rochester.
The Twins optioned Mejia back down to Triple-A after the loss.
