Barrel percentage is way up, line drive percentage is up significantly, k rate is down 5% which is a big drop compared to his career norms, and he's swinging at a career best 29% of pitches out of the strike zone, and his swinging strike rate is a career best as well. His success is not simply due to home run luck, he's made some impressive changes right across the board after 6 full seasons in the big leagues, give the guy some credit where credit is due.
