Mark Cavendish claimed the leader's jersey of Tirreno-Adriatico after his Omega Pharma-QuickStep team won the opening team time trial.
Cavendish led his team over the line in San Vincenzo after they blitzed the 18.5km coastal TTT course. Orica-GreenEdge placed second at 11 seconds, with Movistar in third spot at 18 seconds.
Sky finished in sixth spot, 27 seconds adrift of Omega Pharma-QuickStep.
On Thursday, the riders start in San Vincenzo and take a 166km route to Cascina. The first half of the day is run over lumpy terrain with three categorised climbs, before a flat second half to the line which should suit a bunch sprint.
