    Lompoc, midway between San Francisco and Los Angeles on California's Central Coast, is best known for its prison and its proximity to Vandenberg Air Force Base, where the Defense Department tests missiles and launches satellites into space. It has never been a baseball hotbed, but Duffy has attracted scouts by the dozen for his starts this year, dominating with an unrefined but powerful repertoire. He has perhaps the best fastball in the state among draft-eligible players, reaching 95 mph and sitting in the 90-93 mph range with his four-seamer. He's somewhat mature in build and has had back issues in his past, and needs to get stronger. Duffy also throws a high-80s two-seamer with good armside run, and has shown ability with both a slider and curveball. His mechanics aren't a thing of beauty, one easy indicator of how much work he has to do. He doesn't command the strike zone or throw a changeup, and he hasn't maintained his velocity deep into games either. Nevertheless, he's a lefty with power stuff who has dominated inferior competition.
