Mark Williams, a top-5 center in the 2020 class, officially committed to Duke over Michigan and UCLA.

Williams is ranked as the No. 30 player in the ESPN 100.

"He is a true center who is active, mobile and plays with a self-motivated motor. He impacts the transition game with his ability to run, change directions, and make chase-down blocks or lob dunks. In the half-court set, his defensive presence stands out as a shot-blocker and rebounder. Offensively, he will produce right away as a lob catcher and a drop-off finisher. His low-post, back-to-the-basket game is blossoming, as is his short face-up ability," said ESPN's Paul Biancardi of Williams' game.
