Ian Thorpe's rushed comeback bid for a third Olympic Games ended in ignominy Sunday as he crashed out of the morning heats of the 100 meters freestyle at the Australian trials in Adelaide. The five-time Olympic champion's exit, which followed his failure in the 200 freestyle earlier in the trials, robbed the meeting of its headline act, but Stephanie Rice went some way to easing the crowd's disappointment by clinching the 200 individual medley title in the evening session. The triple Olympic champion eased her way into the race and reeled in world silver medallist Alicia Coutts in the final lap to secure her second title of the meeting despite swimming through the pain of an injured shoulder. Rice, who captured the 400IM title on the opening day, posted a time of two minutes, 9.38 seconds and ensured she will defend both her Olympic medley titles at London. In Thorpe's absence, the spotlight rightly shifted back to Magnussen in the 100 freestyle, as Australia's first world champion in the blue riband sprint charged into the final with a time of 47.93 seconds. The confident 20-year-old eased up in the last 25 meters to be marginally slower than his 47.63 that won him the gold at Shanghai, but set his sights on bettering Brazilian Cesar Cielo's world record in Monday's final. The former bad boy of Australian swimming, Nick D'Arcy won the 200 butterfly title just outside his Australian record to book his London ticket, four years after being kicked off the Beijing-bound team for punching fellow swimmer Simon Cowley at a Sydney night club. World silver medallist Kylie Palmer qualified for the Olympic 200 freestyle with a runner-up finish in the final behind Bronte Barratt, her teammate in the gold medal winning 4x200 freestyle relay at Beijing. Two-time Olympic 100 medley relay champion Jessicah Schipper qualified fastest into the 200 butterfly final, while Beijing silver medallist Brenton Rickard topped the timesheets in the 200 breaststroke semi-finals. Magnussen's bid to break Cielo's record in the 100 freestyle final highlights day five Monday, with triple Olympic champion and comeback kid Libby Trickett making a last-ditch attempt to qualify for London in the 100 freestyle.
