I'm not expecting Leon to maintain his .392 BABIP. It's virtually impossible to do so. I know he won't be anywhere near his June or July last year, but I think he will be serviceable offensively, a good deal better than 2015.
Leon saw 68% and 72% fastballs in June and July, as opposed to about 53% fastballs in August and September. The pitchers obviously adjusted to him, and now it's up to him to make his own adjustments.
