ATLANTA (AFP) - Europe gained a measure of revenge by swimming the world's fastest short course time in history for the 400-metre freestyle relay during the final day of the Duel in the Pool swim meet. Europe may have stormed to victory over the Americans in Saturday's relay race but they lost the overall title in the two-day competition at the Georgia Tech Aquatic Center pool. The USA followed up its dominating performance in day one with 10 more wins Saturday to easily capture the unique head-to-head competition 181.5 points to 80.5 points. The USA won 22 of the 30 races. The Americans have now won all five Duel in the Pool events, beating Australia three times and Europe in the last two. In the 400m relay, Denmark's Jeanette Ottesen, Britain's Francesca Halsall, Aliaksandra Herasimenia of Belarus and Dutchwoman Ranomi Kromowidjojo covered the distance in 3: 27.53 seconds, beating the old mark of 3:28.22 set by the Netherlands three years ago.
