IDK but his career-high FB rate was last year at 26.9 and this year it's about 23, with 50% GB. I guess it's not fair to label it as that - he hits a lot of line drives - but results-wise, a lot of his batted balls end up on the ground, well over 50% for his career. I think to get results like that, I lean toward: elite pitch recognition and ability to make contact and probably "hits it where it's pitched" extraordinarily well.
This guy is pretty confounding. He's not fast. How does he hit like that with 50% of his BIP pulled, and on the ground?
