Good point. Mauer's ineffectiveness is partly due to hitting balls where fielders are, rather than hitting them "where they ain't." Mauer's whole athletic philosophy centers on establishing certain habits, then sticking with them. Through most of his career, his batting style of letting the ball get deep, then executing a super-quick, slashing swing has generated excellent results with hits to the opposite field. However, these days, a lot of balls he used to smoke down the line are peeling off foul into the left field stands, and outfielders like KC's Gordon are positioning themselves near the line to take away more of those previous hits. Mauer also his having more trouble squaring up balls from lefty pitchers, tho for a few weeks last season it looked like he was emulating Kepler's hand position on lefties, and it was working. It's still tempting for me to think Mauer's difficulties come down to some little tweak of his stance or style, not a general decline in his physical ability.
