Richie Porte wins Tour of Romandy

Australian cyclist Richie Porte of team BMC competes in the last stage of the Tour de Romandie UCI protour cycling race, a 17,88 km individual time trial loop from Lausanne to Lausanne, on April 30, 2017

A powerful final day time-trial from Richie Porte saw the Australian BMC leader clinch the Tour of Romandy on Sunday by relegating Britain's overnight leader Simon Yates into second.

The 32-year-old Porte is only the second Australian to win the one week tour after Cadel Evans in both 2006 and 2011.

Yates had taken the overall lead Saturday but had only a 19-second lead on Porte ahead of the challenging 17.8km time trial.

Sunday's stage was won by Slovenia's Primoz Roglic ahead of Porte six seconds back in second and his teammate Tejay Van Garderen in third.

Porte ended top of the overall standings 21 seconds ahead of Yates in second, with Roglic's stage win lifting him to an impressive third overall.
