Filippo Ganna won his first stage at the Vuelta a Espana by dominating stage 10’s time trial as Sepp Kuss’ lead in the red jersey was cut to 26 seconds.
The Italian finished the 26km course in Valladolid 16 seconds ahead of Belgian world champion Remco Evenepoel.
Three-time Vuelta winner Primoz Roglic was a further 20 seconds back in third.
Evenepoel and Roglic made significant gains on leader Kuss who finished the stage in 13th, one minute 29 seconds off Ganna’s time.
Going in to Monday’s rest day Team Jumbo-Visma rider Kuss had a 43-second lead over UAE Team Emirates’ Marc Soler, and was more than two minutes twenty seconds ahead of team-mate Roglic and defending champion Evenepoel.
But Soler gained 17 seconds on Kuss on Tuesday with Evenepoel moving into third, now one minute nine seconds behind the American.
Giro d’Italia winner Roglic is fourth in the general classification standings, a further 27 seconds behind.
Victory was Ganna’s fifth in 2023 and saw him gain revenge on Evenepoel who beat him to the rainbow jersey at August’s World Championships in Stirling.
The Ineos Grenadiers rider posted a time of 27 minutes 40 seconds, averaging 55.968km/h across the flat course.
