ADELAIDE: Multiple world champion Cameron Meyer of Australia seized the overall lead in the Tour Down Under cycle race after winning Friday's fourth of six stages in an audacious breakaway. Meyer of the US-based Garmin-Cervelo team, was among a group of six riders, later dwindling to four, which attacked about 33km into the 124km stage from Norwood to Strathalbyn, and stayed away from the peleton. Meyer sprinted strongly to win the stage from Dutch riders Thomas De Gendt and Laurens Ten Dam. His win broke the stranglehold on the race held by the sprinters, providing its fourth overall leader in as many stages.
