Big, strong kid with thick lower half built to eat innings. Generates his velocity with his size and strength rather than with a quick arm. Just average arm speed. Some length on the back end of his takeaway where he stabs back with his arm. Generates good downward plane.

Williams throws two very distinct fastballs. His 4-seam fastball sits 92-93 and touches 94 but is straight and very hittable. He does not command it very well, though he throws it for strikes. The first time I saw him, he threw more of these than his 2-seam fastball and consistently cell behind of hitters, who also had no problem squaring it up. In the first outing, his 2-seam fastball was unremarkable, with only slight movement. In the second outing, however, he lived off of it, pounding the strike zone with good movement and control, generating weak contact. It ran in on right-handed hitters and featured good sink. When it's on, it's an above-average pitch for him to feature prominently and to play his other pitches off of.
Features a hard, downward break. Has the potential to be an above-average offering. Generally commands the pitch well and keeps it down. At 72-73, it's not a power pitch, which limits its ceiling, but the break is sharp enough to miss bats when he keeps it down.
Below-average pitch without much live. Movement is not sharp, mostly horizontal with little drop. Erratic command. Won't be better than a show-me offering.
Is currently average and has a chance to be a plus pitch, but he doesn't use it enough. Was his best pitch the first night I saw him and was effective with it again the second time in limited usage. Thrown with consistent arm action to his fastball and features good arm-side fade. With a little more movement, it will be a plus pitch, but at the very least, it should be his third above-average offering.
Williams is built like an innings-eating workhorse, but the first time out, his pitches profiled more like an eventual middle-reliever. The second time out, he was much more effective as a ground-ball pitcher, pounding the strike zone with his two-seam fastball and missing bats with his curve. That second version of Williams has a chance to be a 3-4 starter who goes out and logs 200 quality innings per year. If not, his velocity could play up in a bullpen role but his lack of a true swing-and-miss pitch will keep him from pitching in high leverage situations.
