Geraint Thomas claimed the yellow jersey as Team Sky narrowly beat Orica-GreenEdge in the opening team time-trial of the Tour de Romandie.

Both teams were level at the intermediate 15km checkpoint, but Team Sky were able to keep seven riders on course following the climb of the Mont d'Orzeires and swept towards the finish to secure victory by 0.63 seconds.

Katusha, led by Simon Spilak who was third at Paris-Nice last month, had laid down the earlier marker of 21 minutes, 24 seconds.

Etixx-QuickStep, who had former world time trial champion Tony Martin and Rigoberto Uran in their squad, were fourth, some 14 seconds off Team Sky's victory pace at 21:33.

Wednesday's first road race stage runs from Apples to Saint-Imier over 168.1km.

Nicolas Roche stayed with the Team Sky pack for the majority of today's time-trial, helping to set a fast pace, before dropping off to finish back in 126th, 2:13 behind his victorious team-mates.

Dan Martin's Cannondale-Garmin team came ninth in the opening stage, with Martin himself taking 48th in the GC.
