Another sixth place for Scuderia Ferrari Marlboro in the fifth race of the season, this time for Felipe Massa. The Brazilian driver, who set the third fastest race lap, fought for a place in the top four until he was forced to slow significantly to save fuel as, at the second pit stop, the full planned amount of fuel did not go in the tank.

Lewis was delayed at the start as he attempted to pass Nelson Piquet and ran onto the grass as the Renault jinked right ahead of him. Perhaps fortuitously, it dropped him behind the first-lap carnage, and he was able to steer around most of the debris to emerge 15th.

Barrichello threatens to quit Brawn

• Brazilian disappointed at being overhauled by victorious Briton• Ross Brawn denies policy to favour Button over BarrichelloDespite finishing first and second in the Spanish grand prix, Brawn GP's smooth season hit a potential rough patch when Rubens Barrichello said he felt that he rather than Jenson Button should have won the ­race. The Brazilian, who was at a loss to explain why his lead during the first 19 laps appeared to have been compromised by a more favourable strategy for Button, threatened to quit if his team-mate is getting preferential treatment."I need to find out what happened. I'm sure everything is OK but if I get the slightest sniff of the fact that they have favoured Jenson, I will hang up my helmet ­tomorrow," Barrichello told a reporter from Speed TV.Button's win was due to a change in his pit-stop strategy during the race and a tyre problem for Barrichello. "I'm disappointed I haven't won because I thought it was in the bag today," said Barrichello. "I had a great start and took the lead from Jenson going into the first corner. Everything felt quite comfortable. I was surprised when they told me they had switched Jenson from three stops to two."Barrichello was asked if he feared a repeat of the team preferences which blighted his time with Michael Schumacher at Ferrari, when Ross Brawn determined the Italian team's ­strategy. "I have had experience of that and if it happens I won't follow any team orders," he said. "I'm making this clear now. But we have a much more friendly situation in this team. There's no way I'm going to be crying and saying I should have had this or that. I had the ability to win, and I didn't."Brawn denied that there had been a policy to favour Button. "Absolutely not," he said. "The ­strategy change was my decision. The engineers and drivers pool their information and make their recommendations but I make the call in the pit lane and, good or bad, we stand by it. If Rubens hadn't had his problem, it would have been incredibly close.""Rubens got an amazing start," said Button. "He's has been very quick all weekend and as soon as he was in front I knew it would be difficult to get ahead. Then I thought I was in trouble when they switched me from three stops to two. I had to push really hard and it worked out. But I'm surprised. I really didn't expect to win this one."Button's fourth win in five races puts the Englishman 14 points ahead of Barrichello.BrawnJenson ButtonFormula oneMotor sportguardian.co.uk © Guardian News & Media Limited 2009 | Use of this content is subject to our Terms & Conditions | More Feeds
