Minnesota Twins first baseman Joe Mauer is no longer the superstar he once was, which he revealed can be blamed partly on lingering symptoms from a concussion he sustained in 2013.
Speaking to Brian Murphy of the Pioneer Press, Mauer said he still has bouts of blurred vision in the batter's box.
To combat the problem, he said he'll use sunglasses while hitting: “I’ve always been kind of weird about my routine when it comes to stepping into the (batter’s) box, but it’s something I’ll give a shot this spring and see if it helps.
