His BABIP was consistent to that of all his minor league career, so I do not see much of problem.K% will improve hopefully with maturity as a hitter
Not consistently at the extreme he posted his season though. Minors BABIPs tend to be about 15 points higher than in the majors. His high minors BABIP (AA/AAA) in 1,900 plate appearances was .344.
Without digging in any further I might expect his to be in the neighborhood of ~.330, and even that's being optimistic as only 34 qualified batters hit that mark. That's a pretty dramatic difference from the unsustainable mark of .368 he had this season.
Hopefully his strikeout rate will improve, a few more balls in play will offset the BABIP drop, and with the decent speed he's got that will turn into a good chunk of xbh's.
