Lewis pledges to give it his all

Lewis Hamilton (above) said he had shrugged off deep disappointment after the Sao Paulo Grand Prix and pledged to give his all for Mercedes in his final three races before joining Ferrari.

The seven-time world champion admitted he had felt like "not coming back" in a radio reaction at the end of the race in Brazil where he finished 10th but had recovered and now wanted to give his best for "a team I love".

Speaking to reporters ahead of this weekend's Las Vegas Grand Prix, the first of a triple-header on successive weekends, he was asked about a team radio exchange in which he suggested he was ready to walk away.

In the radio transmission, he said "that was a disaster of a weekend guys, the worst the car has ever been. Thank you for contributing to try and great job to all the guys at the pit-stop.
