Winter X games: Shaun White wins fourth consecutive superpipe title

Then, he went big, pumping his fist after landing the McTwist, a move he secretly perfected last year in the backcountry near Silverton, Colo., on a course created just for him.

In other finals on the last day of Winter X:

— Snowmobiler Tucker Hibbert, of Goodridge, Minn., won his fifth straight crown in SnoCross.

— Rookie Enni Rukajarvi of Finland captured the women's snowboard slopestyle final.

— Despite both crashing on the final jump and sliding across the finish line, Canada's Kelsey Serwa ended the reign of France's Ophelie David in women's skier X. Serwa bruised her tailbone and scraped her nose in the win, while David didn't seek medical treatment.

— John Teller, of Mammoth Lakes, Calif., held off defending champion Chris Del Bosco in men's skier X, while Casey Puckett, of Aspen, ended up with the bronze.

"I had the best seat in the house," said the 38-year old Puckett, who recently helped form the American Ski Cross Association to support riders such as Teller. "I was watching Teller and Del Bosco go at it and really I was waiting to see if they made a mistake so that I could capitalize on it. But they had a good race."
