Well, there is a tiny bit of concern for him in that his approach seems to have changed drastically with the added muscle, and hasn't really been helping. Still stellar D, no question there at all, but he's trying to mash everything and swinging/missing a lot more. If he reverts to his previous approach and just allows his added muscle to hit balls harder, the results would likely be much better. Just realize he's not gonna ever hit 20 HRs in a season, so stop trying to do that and get back to being the spray hitter but with a higher EV.
at least, that's my theory. His WRC+ is virtually identical to last season, but wOBA is down. Power is up, OBP is down. Essentially looks like his gains in power are not yet sufficient to cover his large decline in getting balls in play and on base.
