Koci

INF Seth Koci (Indian Trail, 2024) is an athletic uncommitted prospect to know inside of Wisconsin’s senior class. Built at a strong 5-foot-11, 185-pounds, Koci was all over the barrel throughout the entirety of the weekend, highlighted by a pair of two-hit performances. At the plate, Koci swings a quick and direct right-handed bat that has continued to add more power with each look we get at him. Defensively, Koci, who manned second base for a majority of the weekend, held it down, playing with athleticism and also showed sure-handed actions.

Koci certainly caught the attention of our Wisconsin staff. Koci had one of the best workouts of the day among the position player group. Koci is listed at 5-foot-11, 185 pounds with some room left to fill and add strength. His 6.91 second 60 yard dash was in the top 10 for the event. Koci’s defensive toolset is definitely something that opened eyes at the event. He is a smooth and athletic mover to the ball with soft hands and very clean transfers from glove to hand. Koci showcased an accurate arm and threw the ball 84 mph across the infield indicating that he has enough arm to stick at SS in the future.
