Madrid - Sky's Australian rider Richie Porte won the fifth stage of the Tour of the Basque country on Thursday, a 166.1km ride from Eibar to Beasain, but could not dislodge fellow Sky racer Sergio Luis Henao from the overall lead.
Colombian Henao came in second on the day after a penultimate stage containing 10 climbs and marked by a long 50km escape by Spaniard Omar Fraile of Caja Rural, who launched into his effort on the second category Olaberria climb.
Porte and Nairo Quintana are both six seconds behind Henao in the overall standings, with two-time Tour de France winner Alberto Contador another four seconds behind the Colombian leader.
Saturday's final stage is a 24km time trial in the town of Beasain.
