Last year he started pulling the ball more often and it led to a bit of a power surge. This year he has gotten extremely pull happy. He's rolling over or missing everything on the outer half. Absolute best thing he could do is start going the other way with the ball.
So we're going to ignore that last year he was on pace for 3.5fWAR, which would have made him 5th for all qualified shortstops, and instead focus only on 144PAs this year.
