Swimming: Sweden's Sjostrom, 19, regains women's 100m fly world title

BARCELONA (AFP) - Swedish teenager Sarah Sjostrom regained her women's 100m butterfly title at the swimming world championships on Monday, with Australia's Alicia Coutts claiming silver and defending champion Dana Vollmer of the USA bronze.

Sjostrom, who won the 2009 title aged just 15, hit the wall at 56.53sec, with Coutts 0.44sec back and Vollmer, the Olympic champion and world record-holder, at 0.71 behind.

"I didn't have that much confidence after the Olympics, but now I am delighted I persisted in the sport," said the 19-year-old Sjostrom, who failed to win a title at the 2012 Olympics.

Having finished fourth in last year's Olympic final, this was a commanding performance by the Swedish teenager.

Coutts collected her second silver in Barcelona, after anchoring the Australian team who finished second in the women's 4x100m freestyle relay on Sunday night.
