(BEIJING, August 18) -- He Kexin carried out the most difficult moves tonight in the Uneven Bars, but so did Nastia Liukin of the United States. Both scored 16.725, with even the Score A (a measure of difficulty) of both gymnasts being an identical 7.7. According to the rules of Artistic Gymnastics, the gold medal went to He because she made fewer mistakes than Liukin.

The gold medal is He's second of the Games as she won the gold medal in the Women's Team event on August 13. Liukin has now won four medals at Beijing 2008, with her other three medals being the gold medal in the All-Around, the silver medal in the Team final and the bronze medal in the Floor Exercise event.

Yang Yilin won the bronze medal with a score of 16.650. Yang has won a Team gold and the All-Around bronze medal at Beijing 2008.

Despite the disadvantage of competing first, as the first competitor tends to score less due to the conservative attitude of the judges, He dished out a nearly flawless performance and scored 16.725.

Liukin was the second to compete and performed a routine with the same level of difficulty as He's routine. However, six Score B judges found more flaws with her performance and she was ranked behind He despite having the same overall score.

Beth Tweddle of Great Britain finished fourth with 16.625.
