Red Bull team principal Christian Horner says it was necessary to switch Mark Webber to a three-stop strategy because of his relatively short first stint and the rate he was using his tires.
Webber’s strategy ultimately helped him get past the Lotus of Romain Grosjean but he lost out to team mate Sebastian Vettel who only pitted twice.
Horner told Sky: “Mark went through the tire a little bit quicker than Sebastian [in the first stint] and therefore didn’t have the range.”
“So we had to pit Mark and that put an awful lot of pressure and doubt on the two-stop. So when the window opened up to do a three-stop it was the only option we could see to get our way past Romain.”
Horner expected a closer race between his drivers in the final laps but as Vettel passed Grosjean more quickly than Webber did, that never happened.
“We were expecting our drivers to be right together over the last four or five laps,” said Horner, “But Sebastian went past Grosjean quicker than we expected and Mark just took a few more laps with the traffic and the backmarkers that were in the way.”
Webber finished the race seven seconds behind his team mate.
