BRADLEY WIGGINS dropped further off the lead in the Giro d'Italia yesterday as Team Sky team-mate Rigoberto Uran claimed victory on stage 10.
Uran broke away on the final climb to claim victory with Carlos Betancur (Ag2r-La Mondiale) 20 seconds behind him but it was the performance of Vincenzo Nibali, 11 seconds back in third, which will prove a concern to Wiggins.
The Astana rider opened up his lead in the General Classification to 41 seconds from Cadel Evans (BMC Racing) with Uran two minutes and four seconds behind the Italian and Wiggins a second further back.
The 167km stage from Cordenons to Altopiano del Montasio was the first of this year's race to contain an uphill finish.
Wiggins was in the peloton as the riders made their way up the category one climb but while Uran was able to pull away, the reigning Tour de France champion dropped back.
The Briton eventually finished 10th, one minute and eight seconds behind Uran but crucially lost 49 seconds to Nibali in the race for the pink jersey.
Betancur crossed in second behind Uran with Nibali, Mauro Santambrogio (Vini Fantini-Selle Italia), Evans, Rafal Majka (Team Saxo-Tinkoff) and Domenico Pozzovivo (Ag2r-La Mondiale) in the group in third.
"I'm very happy to have taken the win," said Colombian Uran. "It is the first win for me in a Grand Tour and it is very satisfying after getting so close before. It's nice to finally be able to finish off a victory.
"It is doubly special as it came after such a strong ride from the team. It was always the plan for me to attack on the climb and things went to plan. The team rode incredibly all day.
"The result has meant I have jumped up a few positions on the general classification so now I am one second in front of Brad. That is a good position to be in for me and for the team to have two riders there.
"There is still such a long way to go in this Giro but we showed we have one of the strongest teams in the race, if not the strongest."
