McLaren's Lewis Hamilton is on the brink of becoming Formula One's youngest champion with a pole to flag victory at the Chinese Grand Prix.
Hamilton needs to finish in the top five in Brazil on November 2 to take the crown at the age of 23.
Felipe Massa kept the title battle alive with second place after his Ferrari team mate Kimi Raikkonen let him pass while Spain's double world champion Fernando Alonso, finished fourth for Renault after two wins in a row.
Hamiltons's fifth win of the season gives him 94 points with Massa seven behind and BMW-Sauber's Robert Kubica third with 75. Just 10 points remain on the line at Sao Paulo's Interlagos circuit.
He'd been criticised after a wild getaway from pole and clumsy attempt to retake the lead from Raikkonen in Japan last weekend.
But there were no mistakes yesterday and no repeat of the Shanghai nightmare of last season when the rookie skidded off in a race that could also have handed him the title.
