More than one scout has scratched his head about the Arizona right-hander, who has a plus fastball up to 98 mph, a plus changeup and a slider that is a plus at times. Despite this arsenal, he's been hittable due to a tendency to open up on his delivery too early and keep balls up in the zone. Some see him as a reliever, and he should move quickly that way, but his size, arm action and repertoire say that a patient club could end up with a front-of-the-rotation starter.
