Twins star Joe Mauer is changing positions. The team announced that the 30-year-old catcher will be transitioning to first base in 2014. The Twins hope the move will help keep Mauer healthy. He suffered a concussion on a foul tip off his mask in late August and was shut down for the rest of the season. Mauer hit .324 with 11 homers and 47 RBI in 2013.
