RHP Jack Compton (North Clay, 2026) is a name out of Southern Illinois that impressed on the mound this weekend. A high-waisted, wiry build, Compton has a clean and controlled delivery that works in-line down the mound. He has fluidity in his arm action with clear acceleration out front, showing potential for a velocity tick as he continues to physically mature. He threw a complete game (3 IP) one-hitter, attacking hitters with multiple pitches. His fastball sat in the mid-70s, and he showed a sharp biting slider with short, horizontal movement.
