ELS CORTALS, Andorra (AFP) — Tadej Pogacar, the youngest rider in the Vuelta a Espana, ended a day of tense twists on the steep roads of the Pyrenees by taking the ninth stage, as 2016 champion Nairo Quintana seized the overall race lead.

Pogacar, a 20-year-old Slovenian making his Grand Tour debut, was first to the summit of Els Cortals d’Encamp at the end of a short but demanding 99.4-kilometer mountain stage from Andorra la Vella.

The United Arab Emirates rider was followed 23 seconds later by Colombian Quintana. Another Slovenian, Primoz Roglic, finished third.

Frenchman Nicolas Edet started the day in the lead but struggled on the big mountains.

Quintana, who rides for Movistar, is six seconds ahead of Roglic of Jumbo-Visma.

Another Colombian, Miguel Angel Lopez of Astana, is third, 17 seconds off the lead. Spaniard Alejandro Valverde, also of Movistar, is fourth, another three seconds back. Pogacar has climbed to fifth, but is 1 minute 42 seconds off first place.

“There’s still a long way to go,” said Quintana after the stage looking ahead to Tuesday’s time trial.

“The important thing is to get ahead of Roglic. He still has an advantage knowing the time trial to come,” he added.

For a while it looked as if Lopez would take a big lead.

He burst away from the group of favorites with 19 kilometers to go. He had built a gap of some 40 seconds and was chasing the riders ahead in the hope of a stage victory when a ferocious storm struck.

As torrential rain turned to hail, the feed from the TV cameras on the route cut out.

The important thing is to get ahead of Roglic. He still has an advantage knowing the time trial to come.

When they came back on, and the Movistar pair of Quintana and Alejandro Valverde had caught up.

Lopez had blood on his elbow, suggesting a fall in the wet.

“I entered a curve quickly, because my rivals were about 30 seconds ahead, and I lost the bike,” Lopez said after the race.

He struggled home ninth in the stage, more than a minute behind the winner.

As the race approached the finish, another Movistar rider, Marc Soler, was alone in the lead.

He reacted with fury when, with 3.5 kilometers to go, the team ordered the Spaniard to wait. With an angry gesture, he slowed down until Quintana had caught up and helped pull the Colombian to the finish and away from the other contenders, including team-mate Valverde.

That gave Pogacar a chance and he seized it.
