Tyre decision helps Button win

Formula 1 world champion Jenson Button stayed cool in the rain and decided not to switch tyres, a decision which helped him earn the chequered flag at the Chinese Grand Prix on Sunday.

The McLaren driver scooped his second race victory of the season by keeping his nerve and opting to stay out on dry tyres, when many of his rivals chose to pit early and switch to intermediates after the start of the race was hit with showers.

He started in fifth place on the grid, but soon overtook the cars in front of him to get into the lead. Red Bull pair Sebastian Vettel and Mark Webber had started the race in first and second place respectively, but fell back.

Button, who is 30, secured his first victory as a McLaren driver in Australia last month after choosing to switch tyres.

A second appearance of the safety car on the circuit, as debris was cleared after Toro Rosso's Jaime Alguersuari lost his front wing, erased Button's advantage at the front. But he kept his cool to maintain pole and lead McLaren's first one-two of the season ahead of Lewis Hamilton.

"For me, it is my best victory," he said. "Every one you win becomes your best victory but this was pretty tough conditions," he said.

"The good thing is our pace was very good today. It wasn't just the call of weather, it was good pace. At the end we were two seconds a lap quicker than other people."
