OF/LHP Seth Gilliland (Waubonsie, 2025) was a noteworthy two-way prospect. The left-handed hitter has a simple, quiet swing with the ability to backspin line-drives back up the middle. Defensively, Gilliland plays through the ball in the outfield with steady hands and intent, reaching up to 82 mph from a crow hop. He showed some intrigue on the mound too, working his fastball up to 79 mph with some life through the zone and developing feel for his off-speed.
