What is this improved approach at the plate you speak of? The guy had 1 walk in 78 plate appearances since being called back up!! The only difference between Rosario post recall, vs. Rosario pre recall, is that his babip is 100 points above his norm. Guys that swing at everything simply cannot have sustained success at the plate. If he has value, I'd be all for trading him. If he doesn't, I would send him down to AAA, and I'd start from scratch and totally revamp his approach at the plate, even if that means he never gets it and never plays an mlb game for us again.
