Phelps claims third gold

Michael Phelps raced to victory in the men's 200m freestyle swimming, claiming his third gold medal and third world record at the Beijing Olympics.

Phelps finished nearly two seconds ahead of South Korea's Park Tae-hwan in a time of one minute 42.96 seconds.

The American owned the previous record of 1:43.86 and now has a joint-record nine Olympics career golds.

"I just wanted to be out on my own which I had done by the 100 metres mark, that was my goal," said Phelps, who led from start to finish.

"I was out in open water and I was in the middle, which makes it difficult for the other guys to see me.
