RHP Jackson Kottmeyer (Kaneland, 2024) is a young, upside arm to know moving forward. At his first-ever PBR event, the lanky 6-foot-2, 150-pound right-hander showed slight deception in his delivery, moving down the mound well while utilizing a drop/drive lower half, striding slightly across his body, which projects to make it difficult for right-handed hitters to stay in on. Kottmeyer lived in the 79-81 mph range throughout his 'pen with natural arm-side movement. He featured a slurve-y breaking ball at 67-70 mph, featuring some depth and feel to locate. The righty rounded out his arsenal with a changeup at 74-76 mph, showing arm-side fade and maintaining fastball-like arm speed.
