It's actually pretty nuts how much better Vlad's K/BB is than Eloy's. We could be looking at the emergence of a super-elite hitter, although I really don't like to get my hopes up.
Edit: Sorry, I was looking at Eloy's 2016 line. He hasn't played this year, but I'm guessing he's assigned to A+ ball. Still, comparing their A-ball numbers, Vlad is well ahead.
