His xSLG is 503, highest of his career. His xISO is a higher percentile than it's ever been before. I'm not sure increasing his OPPO by 1.5% is affecting that all that much.
If you look at his statcast breakdowns, he's handling FB really well, but struggling with breaking and offspeed pitchings. Looks like there is a huge discrepancy between SLG and xSLG for breaking pitches. Maybe that comes around?
