Mauer will try hitting with sunglasses for the first time during spring training in an attempt to improve his pitch tracking, Brian Murphy of the St. Paul Pioneer Press reports.

Although Mauer hasn't had a concussion since 2013, he has still experienced blurred vision at the plate from time to time. "There are so many different symptoms. For me it was lighting, I couldn't really pick up the ball. It was blurry at times. Where I am here versus last year at this time, I can tell my workouts are better," Mauer stated in an interview. The 32-year-old hit .248/.316/.354 in day games and .276/.352/.396 in night games in 2015, so it appears this move does have potential to help him improve at the dish in 2016.
