INF/OF Haydn Jinkins (Grain Valley, 2026) continues to intrigue our staff each time we see him. At 5-foot-11, 170 pounds, Jinkins swings a quick, rotational right-handed barrel with a level path through the zone. There’s more impact to come as he continues to add strength, but he already showed the ability to drive the ball with authority to the pull side, posting a 93.6 mph peak exit velocity in this look. Defensively, he showed steady actions and an 83 mph arm across the diamond from short.
INF/OF/RHP Haydn Jinkins (Grain Valley) emerged from Saturday’s look as a projectable 2026 athlete to keep an eye on. Jinkins was a standout defensively, showing clean, advanced actions with smooth, reliable hands. His 82 mph infield and outfield velocities were both among the top-3 at the event. At the plate, Jinkins flashed gap-to-gap power, spraying line drives with an all-fields approach. With plenty of room to add size and strength, Jinkins barreled his best ball at 90.2 mph.
