    Eastern Illinois has not had a player taken in the top 10 rounds of the draft since Tyler Kehrer was picked in the supplemental first round in 2008. Klein could break that drought as a power arm with a 94-99 mph fastball and a potentially above-average curveball. Klein moved into Eastern Illinois’ rotation this year after two years in the bullpen and was impressive in an Opening Day start against Arkansas. But overall he’s been more effective in shorter relief stints and likely fits better in pro ball back in the pen. He was dominating at times last summer in the Northwoods League as he was 2-2, 0.86 with only eight hits allowed in 21 innings. Klein’s control is fringy at best, hurt in part by a hook in the back of his delivery and he sometimes has to slow down his delivery to land his curve, tipping hitters. His delivery is relatively simple and shows some reminders of the fact that he was primarily a catcher until late in his high school career.
