Mauer announced his retirement, the Minneapolis Star Tribune reports. "The decision came down to my health and my family. The risk of concussion is always there, and I was reminded of that this season after missing over 30 games as a result of diving for a foul ball," he said.

Mauer went 2-for-4 with a walk and two runs scored in Tuesday's loss to the Tigers.

Mauer is out of the lineup against the Tigers on Wednesday, Mike Berardino of the St. Paul Pioneer Press reports.

Mauer is not starting Sunday against the Royals.
