Nairo Quintana (Movistar) is the new leader of the Vuelta a España following the conclusion of Stage 9.
Winner Anacona (Lampre-Merida) won the stage after escaping the clutches of the peloton within the final 20 kilometres.
Joining Anacona were Bob Jungels (Trek) and Javier Moreno (Movistar), but neither could match the pace of the 26-year-old Colombian.
At first it looked as though Anacona would claim both the stage win and the red jersey of the overall leader, but a late surge from an elite group put paid to his chances of leading the general classification.
Alberto Contador (Tinkoff-Saxo) went on the offensive, and was followed by Joaquim Rodriguez (Katusha) and Quintana.
The group reduced the gap enough to ensure that it was Quintana, rather than Anacona, who slipped into red at Aramón Valdelinares.
However, the stage winner was extremely proud of his efforts.
“I’ve had some great wins, but this one is special. I’ve never won a grand-tour stage before, and I had some tears in my eyes when I was crossing the line,” he said.
Quintana's team-mate Alejandro Valverde, who led the general classification at the start of the day, praised Quintana's efforts throughout the stage.
“The most important is that the leader’s jersey remains on the team,” he said.
“Nairo had good legs, and he was able to go. I was on the wheel of Froome, but I couldn’t follow either, in the end, I sprinted to see if I could get a few seconds.
"The weather wasn’t great for me, so all things considered, I am content.
“We were never hiding anything, Nairo has always been the leader, and I am there. We are there, first and third, and the hardest part of the Vuelta is still to come.”
Stage 10 sees the riders tackle the first individual time trial of the race, a 36.7 kilometre effort from Real Monasterio de Santa María de Veruela to Borja.
