The 6-foot-6 Ross jumped over a ball boy, whipped the ball between his legs and threw down a one-handed slam to clinch the victory. Earlier, Ross donned a Vince Carter jersey, took a lob from high-school teammate Terrence Jones off the edge of the backboard, spun in the air, and then slammed home another one-hander.
Evans jumped over a painted portrait of himself and hurdled Dallas Mavericks forward Dahntay Jones for a dunk in his final round.
Ross earned 58 percent of the fan vote in the championship round. The first round was judged by former Houston Rockets Hakeem Olajuwon, Clyde Drexler, Dikembe Mutombo, Rudy Tomjanovich and Yao Ming.
