02/21/2021 - All-In Membership - San Jose, CA Mathieu is a wiry RHP/3B who has a promising future on the diamond. At 3B, defensive abilities are solid as he displays smooth / athletic actions. Feet are active as he works around balls and plays through with his body. Glove action is clean and present well out front. Range will increase as he improves foot quickness. Throws are accurate with on line carry (84 mph velocity) across the diamond. At the plate, power potential is well above average through an athletic setup. Hands are quick (81 mph exit velocity) and work through a level swing path. He stays inside the ball, utilizing all fields with gap-to-gap pop. Power will increase as he utilizes his lower half more efficiently. On the mound, he works to a controlled balance point, has smooth separation and fires from a clean/loose arm action. He gets strong glove-side lead and stays directional toward the dish. FB ranges from 72-76 mph. Breaking ball shows 11/5 shape with late break. He maintains arm speed on his changeup with arm side run. Off speed stuff show potential as being quality pitches. Control is solid as he throws strikes with all his pitches. Stock on the mound will continue to improve as he builds more arm strength through a long toss program. Mathieu has potential with time and room to progress his game.
