STRATTON, Vt. -- Shaun White is "exhausted" and didn't compete at the U.S. Open snowboarding championships.

The Vancouver Olympic gold medalist was scheduled to compete in the men's halfpipe Saturday.

U.S. Open officials issued a one-sentence statement after the first run of the men's semifinals: "Unfortunately Shaun White is exhausted and not feeling well enough to compete in today's U.S. Open halfpipe event."

Meanwhile, Kazuhiro Kokubo of Japan and American Kelly Clark won their halfpipe events.

Kokubo earned 97.17 on his second run for the men's halfpipe victory.

American Louie Vito, who did three double corks in two of his three runs, finished second with 96.16. Iouri "iPod" Podladtchikov was third, despite landing White's signature move, the double McTwist 1260, as one of three double corks in his second run.

For the women, Clark had 94.17 points. Kaitlynn Farrington was second with 90.33, and Ellery Hollingsworth finished third with 86.33.
