Rule 5 pick Starling Peralta has impressed early on during Diamondbacks' camp.
Peralta, 22, has some work to do with his command, but he has a live arm that intrigues the D'Backs. "I don't think right-handed hitters would be very comfortable standing in there against him," general manager Kevin Towers said. Barring an injury, Peralta will have a hard time cracking Arizona's Opening Day roster, as the rotation and bullpen appear set. It's possible the D'Backs will try to work out a trade with the Cubs in order to keep him.
