Zach McAllister

McAllister's father Steve is the Central crosschecker for the Diamondbacks, and it's obvious Zach has soaked up some quality instruction. Though his body has added six inches and 60 pounds in the last two years, he has maintained a solid delivery. He can consistently throw a breaking ball for strikes and has good feel for a changeup, uncommon traits in a high school pitcher. McAlister started slowly after leading Illinois Valley Central to a runner-up finish in the state Class A basketball playoffs, but his fastball has climbed from 88-89 mph to 90-92 this spring. His slider could use more velocity, and that should come with time. Though McAllister has a thick lower half, he's a good athlete with a loose, quick arm. If he attends Nebraska, he'll get the chance to hit because he generates good leverage and power with his 6-foot-5, 230-pound frame. But it's more likely that he'll sign as a third- to fifth-rounder.
