Darvish is wowing the Rangers, I heard an interview with Napoli today who was absolutely gushing over him. His debut today resulted in 2IP, 2H, and 3Ks. He has 9 pitches, his catchers are going to have to an interesting time figuring out what to call and getting all the signs correct.
Had one double smoked off the wall off him, and when asked about it after the game he said the batter had the wind at his back, thin air of zona, and no, the batter didn't "get him" or some such translation. In short, he's highly competitive, hates giving up anything. Strasburgesque.
