Barcelona, Day One: Nico Rosberg overcomes delays to put Mercedes on top

Nico Rosberg recovered from another disrupted start for Mercedes and their W04 to set the pace on a competitive Day One of the Barcelona test.

Daniel Ricciardo was sixth for Toro Rosso, ahead of McLaren's Sergio Perez as the Woking team again spent much of the day running under the radar. While a largely smooth opening day at the Spanish GP venue, there were two brief stoppages for red flags during the seven hours of track action, the first for Esteban Gutierrez's Sauber when the team conducted a dry-fuel run, and the second when Caterham's Charles Pic pulled off the road after 49 laps.
