Nairo Quintana (Movistar) took a solo win on the first category climb of Alto del Amago at the end of stage four of the Tour de San Luis in Argentina on Thursday.
The Colombian used his climbing prowess to distance his rivals and claim back some serious time on race leader Phillip Gaimon (Garmin-Sharp) - but not quite enough to take the lead from the American. Quintana now lies a tantalising four seconds back on Gaimon overall.
Local rider Sergio Godoy (San Luis) had matched Quintana's pace on the lower section of the final climb but lost touch as the Movistar man pressed on. He claimed second place for his efforts, with Darwin Atapuma (BMC Racing) in third.
British rider Adam Yates (Orica-GreenEdge) put in a strong ride to place 10th on the day and increase his lead in the best young rider's classification and move up to 12th overall.
Tomorrow (Friday) the riders face a 19.2-kilometre individual test against the clock, which should serve to shake up the general classification. The UCI 2.1-ranked Tour de San Luis concludes on Sunday, January 26.
