Richie Porte solos to win stage five in Basque Country

Team Sky continued to dominate the racing in the Tour of the Basque Country on Friday, with Richie Porte taking a solo win and Sergio Henao placing third to maintain his overall lead in the WorldTour race.

Porte put in a late attack from the contenders' group on the last of the day's 10 categorised climbs  to take a solo win and claw back some valuable seconds from overall rivals Alberto Contador (Saxo-Tinkoff) and Nairo Quintana (Movistar). Samuel Sanchez (Euskaltel-Euskadi) came home in second, four seconds behind Porte, closely followed by Henao.

Henao leads the general classification by six seconds over Quintana, and Porte in third at the same time. Contador is fourth at 10 seconds.

With just Saturday's 24-kilometre individual time trial stage remaining, strong performer against the clock Porte is in the ideal position to take the top spot on the podium.

Tasmanian Porte is enjoying his most successful season yet, with an overall win in Paris-Nice and second behind team-mate Chris Froome in Criterium International. He goes into this year's Tour de France as a key support rider for Froome, and is putting a convincing case forward to be a back-up contender in his own right.

With defending 2012 Tour winner Bradley Wiggins also in attendance in July - after he attempts to win the Giro d'Italia in May - Sky has an embarrassment of Grand Tour riches.
