Koopmeiners is an imposing 6-foot-4, 195-pound two-way prospect in the state’s 2027 class. At the plate, Koopmeiners sets up wide and takes a short/compact path to the baseball with easy bat speed and feel for the barrel. The right-handed hitter recorded an 85.8 mph average exit velocity with a max of 90.9 mph. His Blast metrics were also impressive, recording an average bat speed of 69.1 mph topping out at 77.6 mph. Defensively at first base, Koopmeiners has feel for the bag and plays with soft feet that pairs with an accurate arm across the diamond up to 77 mph. On the mound Koopmeiners impressed with his ability to repeat his delivery and arm action. His three-pitch arsenal features a running fastball that sat in the 78-80 mph range and topped 80.8 mph. He also showed feel for a tight breaking slider that he was able to consistently throw to his glove side and a low-70s changeup that he was able to throw for strikes, too.
6/09/23

Also on Friday, Koopmeiners contributed to Midwest Halos Scout’s 15-0 victory by turning in a quality two-way performance. Beginning on the mound, the physical 6-foot-4, 205-pound athlete presented a four-pitch mix, but mainly used the fastball to navigate through his two innings, sitting 74-77 mph, maxing out at 78. In his short outing, the right-hander struck out four batters and only allowed one hit. At the plate, Koopmeiners banged a double off of the wall on a fly, presenting quick hands and a whippy barrel, allowing him to turn on the pitch and drive it.
