The Pacific Northwest keeps churning out big arms, and Jackson Cox caught the most helium throughout the 2021 summer. Running his fastball up to 95 mph thanks to a quick/whippy arm that can be electric with heaviness at the plate, Cox is athletic on the mound even without much use of the lower-half. The slider (79-81) is quickly becoming an elite pitch with 3000+ RPM that is sure to excite scouting departments, and already garners plenty of swings and misses. The 6-foot-1, 185-pound Oregon recruit has some of the highest upside in the class with an athletic frame that should add much more strength in the future, and the pure stuff to make an even bigger jump perhaps as soon as next spring.
