Asian Games 2010, Taekwondo
Match score for Taiwan vs Vietnam: 9:0
Winner: Vietnam.
Here's an article about it
And a video on the full match.
In the middle of the match, the score suddenly jumped from 8 to 9 was because of the spinning kick, you get one more point by doing that (and of course, the sensor wouldn't know about it). Although the video didn't show it, the couch and the judge did discuss it.
Then, the Korean Technician stopped the game, disqualified her, then declared the winner. Judges didn't say anything about it. Not even a rematch with "qualified equipment"
Oh, and apparently the only athlete that could compete with Yang is one of the Chinese competitor.
Smart (and also dumb) move to get rid of Yang earlier in the game, heh.
Oh yeah, and apparently the reporter (Chinese) who interviewed Yang afterward asked her, "Why did you bring a disqualified equipment to the match?"
