Twins manager Ron Gardenhire said it's a big step for Mauer, who could start a rehab assignment while the team is on the road next weekend.
"By the time we get back from this road trip, he'll be on a rehab assignment," Gardenhire said. "That's the hope. If everything goes good and he's feeling good we'll get him on a rehab by the time we get back. And by the next week he'll be ready to play for us."
