Rosberg quickly cut into Hamilton's championship lead by securing victories in Spain (reducing his deficit to twenty points) and Monaco. The latter win was aided by the result of a costly miscalculation by the Mercedes team to pit Hamilton with a 19-second lead during a safety car period (that briefly saw the use of the "Virtual Safety Car" for the first time in F1's history) with 14 laps remaining. Rosberg and Sebastian Vettel did not make pit stops, allowing both to narrowly pass Hamilton by the pit lane exit. Racing resumed on lap seventy-one and Rosberg quickly pulled away, remaining in the lead till the chequered flag. Vettel held off Hamilton for second and third, respectively. As a result, Hamilton's lead over Rosberg in the Drivers' Championship was cut in half, to just ten points. Meanwhile, Button secured McLaren's first points of the season by finishing eighth. This left the Marussia drivers of Stevens and Merhi, along with the other McLaren driver, Fernando Alonso, as the only full-time drivers not to score a point after seven rounds.
