Are you freaking kidding? First of all, Desmond is hitting fine overall. Even with the ugly AB's against breaking pitches, he has a perfectly acceptable (if not decidedly GOOD) batting line for a SS.
Second of all, he's never going to learn to hit MAJOR LEAGUE breaking balls sitting at AAA.
Third, ALBERTO??? Do you remember how godawful he was for us as a starter? What development?? The dude should be "developed" by now. He's 27 (peak age for most players). If that happens, my blood is on your hands.
