    Criswell showed promising stuff coming out of high school, with a fastball that got into the mid-90s at its best, and a projectable, 6-foot-3, 185-pound frame. He was a projection arm who scouts wanted to see go to college and add strength and consistency—which is exactly what he did. Criswell stepped into a high-usage reliever role as a freshman and led Michigan with 24 appearances while posting a 2.23 ERA. While his walk rate was a bit erratic, he improved that mark in his second season as he transitioned into a starting role. Again, he had success, posting a 2.72 ERA and improving his strikeout and walk rates. As a junior, Criswell is now listed at 6-foot-4 with a strong, 225-pound frame and a solid three-pitch mix. His fastball regularly gets anywhere from 94-97 mph, and he pairs the offering with a slider and changeup that both have average potential. Scouts would have liked to get more time to bear down on Criswell this spring, but he threw just 24 innings over four starts, getting hit around a bit by Pepperdine in his last outing. There is some concern about whether Criswell fits best in a starter or reliever role. He has enough stuff to succeed in either, but without improved control at the next level (he’s walked 4.5 batters per nine through his Michigan career) he might fit best in the bullpen. However, he has taken steps to improve the walk rate each season, so he could simply continue learning how to harness his repertoire and limit the damage he does to himself. Criswell is a day one pick in a normal draft and should be off the board by the third round.
