The two-time team time trial world champions produced an excellent performance on the hilly 37.9km course in eastern Spain, starting on the Mediterranean coast to the east of the city of Murcia, and finishing in Orihuela.
With no time checks along the course, it was difficult to track teams’ progress through the stage, but BMC looked smooth throughout, with only one rider dropping off the back towards the very end of the stage.
However’s Quick-Step’s time of 44-06 was comfortable beaten by BMC Racing, who stopped the clock at 43-17.
Led across the line by Polish rider Lukasz Wisniowski, Sky finished 21 seconds in arrears.
Tomorrow’s stage sees the riders tackle a rolling course finishing in Denia, with a third category climb close to the end of the stage.
However the overall race is likely to be decided on Saturday’s stage four, which features the only summit finish of the race.
