The Twins are moving Joe Mauer out from behind the plate and transitioning him to first base in 2014, the team announced. The move was made due to long-term health concerns, though he is now free of concussion systems and working out with restrictions.
“After consultation with doctors from Mayo Clinic and team doctors, and given the inherent risks of future injury at the catcher position, the organization and Joe determined that it would be in the best interest of both him and the Twins for a position change,” said the club in a statement.
Mauer, 30, missed more than a month with a concussion after taking a foul tip to the facemask this past season. He’s also missed time with back, quad and knee problems over the years. Catching is a rough business and those guys usually don’t remain productive into their mid-30s.
