It's pretty clear to me that Mauer is much healthier than he has been in the last two years. His BB% is back up, and his K% has dropped back down, those two numbers alone to me show that he is seeing the ball better. His ISO is back to his career norms as well (up 30% from the past two years) this indicates he is making much stronger contact and yes, seeing the ball well again. His BABIP is 20 points below his career norm, so "luck" isn't the reason why he is a .800 OPS guy this year. His WAR in 2/3rds of this season has already equaled his WAR from the last two years combined. In fact he is on pace for a 3.0 WAR season, which is impressive from a 1st baseman. Currently he has the 11th best WAR for first baseman in the MLB. Ahead of guys like Chris Davis, Mike Napoli, HanRam, and Adrian Gonzalez. Mauer doesn't get near enough credit around these parts and from Twins fans as a whole.
