Bradley Wiggins has become the first Briton to win three medals at an Olympics since 1964, while JamPICTURE BY TIM DE WAELE Great Britain can hold their head up high after scoring two gold medals, a silver and a bronze over the past six days of track racing at Athens. But they might have been able to claim another were it not for a decision which kept Jamie Staff out of the Keirin final, for which he believed he'd qualified. Team GB added the bronze medal to their tally after Bradley Wiggins and Rob Hayles took third in the Madison on Wednesday, despite crashing, which was won by Australian pairing Graeme Brown and Stuart O'Grady [see separate story]. It meant that Wiggins took his third medal of these Games having already taken gold in the individual pursuit and silver in the team pursuit, making him the first Briton since athletics star Mary Rand in 1964 to win three medals at a single Olympic Games. But there was disappointment for former BMXer Jamie Staff in the Keirin event. The current world champion took third place on the line in the second round of the event, beating eventual silver medallist Jose Escuredo of Spain, but was relegated to last place in the heat after an 'earlier infringement', believed to be moving down on the track into the path of a following rider. Perhaps understandably, Staff chose not to start in the Keirin event held to determine places seventh to 12th. Australia's Ryan Bayley won the gold medal ahead of Escuredo, with Bayley's compatriot Shane Kelly taking bronze after a crash judged to have been caused by Germany's Rene Wolff, who finished third on the line, and Josiah Ng of Malaysia felled Frenchman Mickael Bourgain in the sprint for the line. Kelly managed to stay upright and was rewarded with a bronze medal.
