Button celebrates his 200th GP with win in Hungary

McLarens Jenson Button celebrated his 200th Formula One start by winning the Hungarian Grand Prix on Sunday after a thrilling race decided by tyre choices in the slippery, wet conditions.Red Bulls Sebastian Vettel was second despite an error-strewn race to increase his championship lead over team mate Mark Webber to 85 points and move him closer to defending his title with eight races left after the mid-season break.Ferraris Fernando Alonso was third.Briton Button sealed his second victory of the season after being wheel to wheel with Lewis Hamilton only for his team mate to drop back to fourth after a choosing the wrong tyres in the rain and then serving a drive through penalty following a spin.With cars sliding around as drizzle and tyre strategies came and went, the less than capacity crowd at the ageing Hungaroring were treated to a string of overtaking moves at a twisty circuit where passing had been difficult in the past.Vettel made a good start from pole but Hamilton, winner of the previous race in Germany last Sunday, kept on the worldchampions tail having been second on the grid. The slippery track contributed to Vettel running wide early on and the Briton saw his chance to speed past before his afternoon went sour.Button, third in qualifying and winner of the rain-hit Canadian GP, then also overtook the German in partially wet conditions as McLaren again showed their race superiority over the previously dominant Red Bull.
