"The MRI was good," manager Paul Molitor said Saturday. "There was just a little sign of an old injury. We're hoping he can do some light swinging over the weekend, and take batting practice Tuesday."
Molitor said he wants to see Sano return, even though there's little time left in the season. The Twins open their final homestand of the season on Tuesday, with three games against the Tigers followed by three with the Mariners before closing the campaign with a six-game road trip.
"It sends the message that you play the year out," he said.
Sano has played 106 games this season, with a .236 batting average and 23 home runs.
