Australia's Cate beats Missy to win 100 metres freestyle gold

Cate Campbell of Australia won gold in the women's 100 metres freestyle at the world championships in Barcelona on Friday.

Campbell clocked a time of 52.34 seconds, with Sarah Sjostrom of Sweden taking silver in 52.89 and Ranomi Kromowidjojo of the Netherlands bronze in 53.42.

American teenager Missy Franklin, who has four golds this week, was fourth.

American Ryan Lochte won the third 200 metres backstroke gold of his career at the world championships on Friday.

The decorated 28-year-old clocked a time of one minute 53.79 seconds, with Radoslaw Kawecki of Poland taking silver in 1:54.24 and Lochte's compatriot, Olympic champion Tyler Clary, bronze in 1:54.64.

Lochte, who won 200 metres individual medley gold on Thursday, is only the second man to win three 200 backstroke titles after compatriot and world record holder Aaron Peirsol, who won four in 2001, 2003, 2005 and 2009.

Lochte was champion in 2007 and at the last world championships in Shanghai two years ago.
