Sullivan Fleming is a 2027 RHP/OF with a lean 5-foot-10, 150-pound frame and fast-twitch athleticism. On the mound, Fleming works from a short inward turn into an athletic move down the slope, utilizing a loose, clean, full-circle arm action. His fastball sits 76–79 mph (T79) with a lower-spin profile (1760 avg rpm), and he shows feel for a 61–68 mph curveball with gradual shape and a developing 62–74 mph changeup that flashes arm-side fade. At the plate, the right-handed hitter shows quick hands and a short, rotational swing from a balanced setup, posting standout batted-ball metrics with a 96 mph max exit velocity and a 309-foot peak distance. He’s a 6.98 runner with impressive burst (1.61 10-yard split) and a 27" vertical, and his 81 mph arm plays well from the outfield. Fleming’s athleticism and two-way profile make him an intriguing follow with plenty of physical projection remaining.
