Mauer, placed on the paternity list on Wednesday, was replaced by Chris Herrmann, who started at catcher and batted seventh.
Catcher Drew Butera was called up from Triple-A Rochester to take Mauer's place on the roster. Outfielder Oswaldo Arcia, who was also a possibility to replace Mauer, left Tuesday's game with Rochester in the third inning, but it was because he felt dizziness.
Butera was hitting .215 (17-for-79) with two doubles, two home runs and 10 RBIs in 25 games for Rochester. He was expected to be in uniform for Wednesday's game in Anaheim.
