| Big, projectable kid throwing from a 3/4 arm angle. Rocks a bit in his delivery, but fairly compact and clean overall. Should be clean enough to stick in a rotation if the rest of the profile so warrants. |

Heavy fastball. Suspect given projectable frame and height that there's more velocity to come here, hence the slightly aggressive future grade given current velocity. Even if it doesn't, he's got some sink on it and commands the pitch well. |

About half of these, mostly in the higher end of the velocity band, showed true tight slider tilt; if he had only thrown those I'd have this as a future plus pitch for him. Grading the pitch overall a half-grade lower because much of the lower end of the velocity band was really slurvy and hung too much. Has the potential to develop into an out pitch for him with greater consistency. |

Flashed as an average pitch a few times. Was far too often too firm and left high and in the hitting zone. Threw a few pitches even harder than this that were difficult to classify but probably best fit as a hard change. That type of fuzziness is not atypical for teenage pitchers. |

Local prep arm that the Mariners signed for $325,000 out of last year's draft in the 11th round. Better command profile and polish than I expected for a 19-year-old 2018 draftee making his second full-season start, which makes sense given aggressive jump to full-season ball. Still pretty raw overall, of course. Things could go in many, many different directions depending on where his stuff settles in, his ability to handle a full-season workload, and so on. For now, he's a good live arm worth tracking, with potential to turn into more in a variety of different roles, but extreme variance. Keep an eye on him.
