MANAMA, April 4, 2008 (AFP) - World championship leader Lewis Hamilton admitted Friday that he made a rare error leading to him crashing out of practice ahead of Sunday´s Bahrain Grand Prix.

The 23-year-old McLaren driver said it was his mistake that led to his session ending early and leaving Ferrari to dominate and take pole position.

He said: "I made a mistake. I got caught out by the kerb and it spun me around. That kerb it is quite spiteful.

"If you hit the wrong part of it is spits you off. That barrier is quite close to the side of the track. That´s racing. It won´t happen again."

Hamilton said the accident would not have any negative effects on him, his car or his race weekend.

"There is no impact on the weekend. There are no bruises to report from me and we completed most of the session, making some good steps forward," he said.

"Ferrari look very quick, but you don´t know what fuel loads they are on. I´m hoping that fuel corrected it is a lot closer than things seem.

"Ferrari did a good job in the last race. We just have to focus on our own work. Pace-wise I feel quite comfortable. We saw from Malaysia that we had the pace to run with them in the race."
