RHP Nate Kos (Libertyville, 2025) boasts all sorts of projection in his 6-foot-1, 145-pound frame. His arm plays loose and clean out of the glove into a ¾ release, producing a running fastball at 73-76 mph. He showed feel for two quality off-speed offerings; the first being a sharp 11/5 breaking ball with short shape, 68-70 mph - the second being a fading changeup at 70-73 mph.
