Jacob Tucker wins NCAA slam dunk contest (Video)

Earlier this month, Jacob Tucker's dunking audition video went viral.

The audition worked: The 5'10" guard has won the 23rd college basketball dunking championship.

The smallest guy in the competition - going against a slew of Division 1 players - scored a perfect 50 in the first round with an amazing through-the-legs dunk (one that he showcased in his audition YouTube video).

NBA legend Karl Malone was among the judges' wowed by the diminutive dunker.

Tucker also caught a pass off the side of the backboard and threw one down, then culminated his performance by soaring over a ball-boy and nailing a crowd-pleasing reverse dunk.

"It's unbelievable," he said after winning the championship.
