At the London 2012 Olympic swimming competition today, China's Sun Yang easily posted the quickest time of 14:43.25 in the men's 1500 freestyle, ahead of Olympic champion Oussama Mellouli in 14:46.23 and Canada's Ryan Cochrane in 14:49.31, other medal contenders dropping like flies despite of their chance of getting into the final increasing with each fall. Our guy Pál Joensen one of these. Australia led the women's 4×100 medley prelims in 3:55.42 and USA the men's 4×100 medley prelims in 3:32.65.
