Photos: Grayson Allen wins 2014 McDonald's/Powerade slam dunk contest

Grayson Allen, the 6-foot-4 guard from Providence (Jacksonville, Fla.), was sort of an afterthought in the McDonald's All-American slam dunk contest, which was the premier portion of the Powerade Jam Fest at the University of Chicago on Monday.

Allen is going to Duke. He's a shooter. He looked fantastic in the 3-point contest, where he took second to Indiana-bound James Blackmon of Marion (Ind.)

But to the surprise of some, he began jumping over people. Teammates, rap stars and finally over future Duke teammate and Chicago native Jahlil Okafor, a 6-10 post from nearby Whitney Young (Chicago). To commemorate the dunk, Allen even put on a Duke jersey.

That brought the house down and brought Allen the title before a national television audience.

He beat out Theo Pinson, a 6-6 guard from Wesleyan Christian Academy (High Point, N.C.) headed to North Carolina and Kelly Oubre, a 6-6 guard from Findlay Prep (Henderson, Nev.) headed to Kansas, in the finals.

The four teams — West and East for boys and girls — will practice Tuesday before facing off in the games Wednesday at the United Center. Allen and Okafor play for the West squad.

Tyus Jones, a 6-1 guard from Apple Valley (Minn.) and another Duke signee, won the skills competition. Among the girls,  Alexa Middleton, a 5-8 guard from Riverdale (Murfreesboro, Tenn.), won both the skills and 3-point contests. Middletown, who is headed for Tennessee, lost to Blackmon in a head-to-head 3-point contest 21-20. Middleton just had to make one shot on the final rack, but missed four straight.
