5-10/175, added 15 lbs of muscle, especially lower half, looking strong...arguably the best high school pitcher in Hawaii in 2023...excellent rhythm, tempo, delivery & mound presence, looks like a pro...seen him up to 89 w/command & 2300+ spin...CHG is best out-pitch, excellent feel & deception w/+confidence, can throw in any count, advanced touch & command, ends up at least plus, equally effective vs LH/RHH's...plus feel for true SL, doesn't have crazy spin but ability to command plays SL up, induces chase-K's vs RHH's often...K-out pitcher, feel ends up a low BB rate guy...quiet & reserved off the field, completely different demeanor on the mound as fiery competitor...big game pitcher, cool under pressure, exudes confidence, a winner...truly feel will prove a lot of doubters wrong...would have 10+ big DI offers if was 6-02, should already be committed...reminds me of David Cone...#10 ranked Hawaii 2025...strong DI recruit.
