Mauer also started behind the plate for a third straight game on Thursday, but is expected to get a day off from catching duties during a three-game set in Baltimore this weekend.
"He came in and I didn't even ask him -- he was catching these three games," Twins manager Ron Gardenhire said. "And then we'll see in Baltimore. He wants to catch. He really does. But [Ryan] Doumit does too, so some day in Baltimore [Doumit] will catch."
