RHP, Ayden Sepich, Columbia, 2028
Uncommitted. Lean and projectable 5-foot-9, 150-pound frame. Came out of the bullpen for the Eagles and looks to be a name for our staff to follow throughout the coming years. The slender right-hander is an easy mover with a simple delivery, working with a shorter leg-lift into a tall/fall operation that stays in-line with a high ¾ arm action. The fastball played around 80-84 mph with some tilt through the zone, setting up a changeup at 71-74 mph with similar actions, and a curveball in the upper-60s with over the top break and some depth. High-follow arm to keep tabs on.
