04/30/2017 - College PREP - Fairfield (Sacramento), CA Riley is a well-built right-handed pitching prospect who has good upside and graduates in 2018. On the mound, Riley has an easy motion with balanced, on-time mechanics. He throws from a 3/4 arm slot with a loose arm action. He picks up his target early and stays square with a controlled landing. Riley has good arm side movement on his fastball at 76-80 MPH. He controls his late breaking curveball at 67-70 MPH. Riley's changeup is deceptive with run mimicking his fastball. Overall, Riley has a solid approach on the mound and potential to get even better.
