| Summary: Sullivan brings real athleticism and impact speed to the profile, grading out as a true plus-plus runner who changes games once he’s on base, an athletic profile you would expect from the grandson of a Heisman Trophy winner. Drafted in the seventh round out of South Alabama, he’s consistently shown on-base traits that play—working counts, taking walks and HBPs, and avoiding reckless chase. The swing decisions are generally sound, but the offensive profile still has some friction: passivity can creep in, and quality secondaries have beaten him at times, leading to elevated strikeouts and uneven contact. When he’s decisive, he can handle fastballs and produce loud contact, flashing above-average raw power and exit velocities, but the bat path skews flatter and pull-heavy, which limits consistent carry unless he gets the ball in the air more often. Defensively, the speed gives him real versatility. He can cover center field in a pinch thanks to range, though reads and routes can be tentative, making a corner outfield role a more natural fit long term where the arm and speed play cleanly. On the bases, he’s aggressive and efficient, with the instincts and acceleration to post high stolen-base totals and add pressure throughout a game. The overall outcome hinges on how much contact the bat produces against better pitching—if he hits enough, there’s a path to an everyday role driven by OBP and speed; if not, he still profiles as a high-energy platoon or fourth outfielder who impacts games with his legs, defense, and approach. | |||||||||||
