I think I posted it earlier but I will post it again.
The reason he got downgraded was a massive drop in Discipline. I don't know if it is warranted or not but that is where he took the hit this past update. He also got slight downgraded on contact and power vs lefties. He is actually hitting lefties pretty well so far this season so I am not sure where those came from. I think he will go back up in that stat next time.
As a fan it is great to just look at his overall offensive numbers and praise him but in this game, for better or for worse, you have to take into account lefty and right splits, strikeouts, walks, fielding, position played, etc.
