The greatest men's and women's high school basketball players descended upon Chicago last night for a handful of All-Star festivities including the three point and dunk contests ahead of the annual McDonald's All-American games.

Alabama signee Collin Sexton, a 6'3 guard from Georgia, took home the dunk contest crown with a one-handed 360 windmill receiving a perfect score of 70 to beat out Troy Brown Jr. and Jaylen Hands in the finals.

The 40th annual McDonald's All American boys game will tip off at 7pm EST tomorrow night immediately following the 16th girls game, which is scheduled for 5pm EST.

Watch Sexton's winning dunk below, followed by all of the highlights from the Powerade Jam Fest.
