Formula One: Webber wins Brazilian Grand Prix

Mark Webber won the season-ending Brazilian Grand Prix on Sunday after Red Bull teammate Sebastian Vettel struggled with a gearbox problem.Vettel, who had already secured the Formula One title, still finished second after letting Webber get past him almost halfway through the race at the 4.3-kilometer (2.6-mile) Interlagos track.Jenson Button of McLaren finished third to secure second place in the drivers standings.Webber easily passed Vettel on lap 30 after his teammate reduced his pace after being told by the team that there was something wrong with his gearbox.Webber finished third in the championship with the victory, his first of the season. It was his seventh overall in F1, and the second in Brazil after winning in Interlagos in 2009.Vettel, the winner in Brazil in 2010, won 11 races this season but finishes the year without victories in the last two races. He retired on the first lap in Abu Dhabi because of a puncture.The second-place finish came a day after the two-time champion captured his 15th pole position of the season to break Nigel Mansells 19-year record. The 24-year-old German was trying to win his 12th race of the year, which would allow him to finish the season only one victory shy of Michael Schumachers record set in 2004.Vettel had clinched the title four races ago, at the Japanese GP. Red Bull also had already won the constructors championship, with McLaren finishing second and Ferrari third.
