BEIJING -- Chinese judoka Yang Xiuli won the women's 78kg gold by a referee's verdict after a tie in overtime at the Beijing Olympics on Thursday, adding the second judo title to China.

In the five-minute final bout, both Yang and his Cuban rival Yalennis Castillo managed a koka which led to a five-minute golden-score duel

After a suffocating five-minute overtime, their scores were still unchanged, despite a koka was given to Castillo which was later canceled.

Then the referee and judges of the gold medal match made a final verdict which awarded Yang in blue the winner. Judge Akiko Amano from Japan raised blue flag, judge Cathy Mouette from France raised white and the referee Franc Ocko from Slovenia raised a decisive blue.

According to judo's rule, if there is still a tie after overtime competition, a panel of three, one referee and two judges, will made a verdict based on the two players' performance.

Jeong Gyeong-mi from South Korea and Stephanie Possamai of France shared the bronze medals.
