Quintana grabs Romandie lead after stage two win

Morgins: Colombia's Nairo Quintana seized control of the Tour de Romandie by winning Thursday's second stage in Morgins after defending champion Ilnur Zakarin was stripped of his victory.

Quintana, who was jostling with fellow escapee Zakarin in a sprint finish, crossed the line in second behind the Russian, before the Katusha rider was downgraded by race officials for interfering with his rival.

"Zakarin would have won anyway but he boxed me in. I'm not commenting on the decision of the judges," said Quintana.

"It's not easy to win here given the plateau. Being able to do so is a very good sign."

The pair finished 26 seconds ahead of a group headed by Portugal's Rui Costa, with Rigoberto Uran and Thibaut Pinot also clocking the same time in the Swiss mountain village.

Podium hopefuls Rafal Majka, Bauke Mollema and 2010 winner Simon Spilak all finished together as well, but American Tejay van Garderen lost over a minute.

Chris Froome's hopes of a third title -- after wins in 2013 and 2014 -- went up in smoke as the Briton was slowed by a puncture 20 kilometres from the finish and found himself well off the pace even before the final climb of the 174km route from Moudon, the Tour de France champion finishing over 17 minutes in arrears.

Quintana, who was second to Froome at last year's Tour, took over the leader's jersey from Ion Izagirre and goes into Friday's 15.1km individual time trial around Sion with an 18-second advantage over Zakarin.
