Cooper Jesperson, Eau Claire Memorial (WI), 2025
Positional Profile: RHP/OF
Body: 6-3, 174-pounds. Athletic, long levers, more projection coming.
Delivery: Athletic with dynamic lower half, drives hard with lower half down the mound with good direction.
Arm Action: RH. Full arc, online, very quick arm, low 3/4 slot, repeats.
FB: T95, 90-93 mph. Late boring running action, ball jumps out of hand, shows impressive command of the baseball. T2587, 2449 average rpm.
SL: 76-79 mph. Late sweeping slider, nasty bite to the pitch, pairs well with the fastball, serious out-pitch weapon, Major League quality. T2812, 2742 average rpm.
CH: 74-76 mph. Thrown with fastball intent, late depth at the plate, swing and miss weapon, nasty. T1923, 1883 average rpm.
7/18/23

Listed at 6-foot-3, 165 pounds, we got our first look at RHP/OF Cooper Jesperson (Eau Claire Memorial, 2025), who was impressive on both sides of the ball. At the plate, the incoming junior featured a whippy barrel that made efficient contact and worked with an opposite-field approach. The Eau Claire Memorial two-way impressed on the mound, which garnered attention on Tuesday. Jesperson displayed a high leg kick that transitioned into a smooth delivery with intent through extension. He showcased a whippy, fluid arm action that works quickly through the arm motion. His repertoire contained a fastball, a slider, and a splitter. Jesperson ran his fastball up to 85 mph as the pitch seemed to jump out of his hand without effort. His slider was the most impressive of the three pitches as it contained a tight break throughout with feel for placement. His third pitch, a splitter, was a complement to the first two pitches and contained some depth with a foundation to develop the pitch into a respectable third option. Jesperson’s performance and display of ability at Tuesday’s event puts him on our radar for the rest of the summer and into his junior season.
