Drafted 12th overall out of high school in Canada by the Marlins in 2015, traded to San Diego in the Andrew Cashner deal this summer. Naylor's body is mature and the frame is pretty well maxed out for a 19-year-old. His physique is one that will carry ample maintenance weight throughout its middle, though he shows impressive present agility and some explosiveness to his actions. He's a hyper-aggressive hitter whose quality barrel control and plus bat speed have hindered him in developing much of an approach to date. A good portion of his plus raw power should play in the form of hard line-drive contact and carry to the pull side, though the approach will limit the game utility enough to where it's like to wind up short of a true impact bat.

He's not a base-clogger, but the speed is decidedly below-average and likely to peter out quickly. It's a first base-only profile, and while he is quite raw at present his actions suggest potential to develop into a won't-hurt-you defender there. The tools to become a solid big-league hitter are here, though this is a higher risk prospect due to proximity and a bat-first profile that will require his hit tool max out in spite of the approach.
