View Draft Report
Woo wasn’t widely known in high school, but he showed such promising stuff in the Alaska League the summer after he graduated that teams tried to sign him as a nondrafted free agent. He stuck with his commitment to Cal Poly and spent three seasons bouncing between starting and relieving for the Mustangs. Woo’s stuff ticked up this spring to make him one of the fastest risers on the West Coast, but he suffered an elbow injury in mid April and had Tommy John surgery. Woo’s fastball sits 91-95 mph as a starter and 94-96 mph as a reliever out of a loose, clean delivery. He’s a good athlete and still has room to add strength and throw harder, with some evaluators predicting he will touch 100 mph in the future. Woo’s fastball has been hittable at times, but when he locates it to his arm side, it gets under righthanded hitters’ hands and leaves them largely helpless. His slider is developing and began flashing above-average shortly before he got hurt. Woo was used heavily at Cal Poly and will need to rehab after surgery, but teams are interested in his arm strength and athleticism and see him as an intriguing buy-low candidate.

BA Grade/Risk: 50/High
Track Record: Woo fell under the radar in high school but pitched so well in the Alaska League after his senior year that teams tried to sign him as an undrafted free agent. He instead stuck with his commitment to Cal Poly and spent three seasons bouncing between the bullpen and rotation, capped by a breakout junior year that was cut short by Tommy John surgery. The Mariners drafted Woo in the sixth round in 2021, signed him for $318,200 and guided him through the rehab process, a decision that paid off when he returned to the mound in 2022. Woo zipped up three levels to High-A, then emerged in the Arizona Fall League with an 0.84 ERA in five starts.
Scouting Report: Woo is an athletic 6-foot-2 righthander with an easy, explosive delivery. His plus fastball sits 93-94 mph and touches 96 with above-average ride that helps it miss bats in the strike zone. He primarily pitches east to west with his fastball, but he has the command to elevate it and get chase swings above the zone. Woo complements his fastball with a sweeping, mid-80s slider that he commands to his glove side and plays well against righthanded hitters. The quality of his slider can be inconsistent, but it generally ranges from average to plus and is consistently competitive. Woo's firm, 87-90 mph changeup has progressed rapidly in a short time and flashes above-average with late drop and run away from lefthanders. He is a good athlete who pounds the strike zone with above-average control, though he occasionally gets too much of the plate. His command should sharpen the further he moves away from surgery.
The Future: Woo has the ingredients to be a mid-to-back-of-the-rotation starter, but he has to show he can maintain his stuff over a full season. That will be his primary goal at Double-A Arkansas in 2023.
Scouting Grades: Fastball: 60. Slider: 55. Changeup: 50. Control: 55

August Update: Woo was one of the fastest risers in the 2021 draft class before going down with an elbow injury that required Tommy John surgery. The Mariners drafted him in the sixth round and rehabbed him, a decision that is being rewarded. Woo returned in early June and immediately showed an upper-90s fastball and a potentially plus slider. He earned a quick promotion to High-A Everett and appears to be on the fast track.
