Very high three-quarter arm slot, borderline over-the-top, average arm speed, clean arm action; mild effort, leverages frame effectively to deliver with vertical extension, struggles to maintain consistent release point
Wilmington Blue Rocks (High A, Royals)
Average command of pitch, some wiggle to miss bats, arm-side run; can show heavy and boring pitch when he's consistently on top of it; works well east-west, generally stays off barrels but will leak up in zone; better late life on pitch when seen in second outing
Shape shifts between 11-5 and 12-6; average command, will flash plus with above-average bite, inconsistent present depth and arm speed, ball-to-strike will get loopy early in counts; 12-6 shows chase potential, can bury it as a put-away
Only showed sporadically; flashed average command on a couple, inconsistent present; plays pretty straight, lacks tumble, moderate velo separation; below-average projection
Blewett is a tall, projectable right-hander, and there's potential for two plus pitches if he can consistently replicate his motion and get his release point down pat. The changeup doesn't present as a reliable third pitch right now, and is in need of significant development. Blewett could rise to the Majors as a middle reliever with two plus pitches, but for him to play out as a starter, he'll have to gain more traction with a third-pitch to keep lefties at bay.
