A physically impressive freshman, Jack Renze (St. Thomas Aquinas, 2028) delivered one of the loudest all-around performances of the day, regardless of class. At 6-foot-2, 180 pounds, Renze swings with intent from a level right-handed stroke, flashing advanced bat speed and impact potential. He peaked at 101.4 mph off the bat with a 348-foot max distance—ranking third and fourth at the event, respectively. Defensively, his arm strength stood out, firing an 89 mph bullet across the infield, and he showed athleticism with a 6.77 60-yard dash. A name to know in Kansas’ 2028 class.
