Primoz Roglic won the stage 10 time trial at the Vuelta a Espana to take control of the red jersey.
The Slovenian Jumbo-Visma rider completed the 36.2 kilometre course in France, running from Jurancon to Pau, in 47 minutes and five seconds, which saw him finish 25 seconds clear of New Zealand's Patrick Bevin.
Remi Cavagna of Deceuninck-Quick-Step was third, 27 seconds off the pace.
Tadej Pogacar, who had won stage nine for UAE Team Emirates, saw his challenge fade over the second half of the course.
Roglic's impressive performance helped the 29-year-old open up a commanding lead of 1min 52secs in the general classification standings - with overnight leader Nairo Quintana dropping down to fourth after struggling in the time trial.
Quintana's Movistar team-mate Alejandro Valverde is now in second place overall, with Miguel Angel Lopez (Astana) third.
Colombian climber Quintana, meanwhile, now has three minutes to make up on Roglic.
"Every time trial you try to do as fast possible, and it was the same mission today," Roglic told Eurosport.
"I'm happy with the performance for sure. I just tried to go all the time as fast as possible and yeah, it was enough at the end."
Ireland's Sam Bennett finished well down the field and is 157th in GC.
