Button says Bahrain win the best of '09

Button scored his third win in four races after taking his Brawn car to the top step of the podium despite starting from fourth position.

The Briton admitted that his pass on third-placed Lewis Hamilton in the opening part of the event had won him the race.

"He (Hamilton) is very difficult to overtake, but on the first lap he made a few mistakes I dived down the inside and on the straight I thought I could get alongside him," said Button.

"I did but he pushed his button and got ahead, but I got him into first corner. That move made the race for us.

"This win was the best of the lot. We didn't have that competitive edge. It is the fourth flyaway, we have a lot of bits that need to be changed and getting a bit aged, so to come away from this race is great and we are now looking at improving the car."

Button increased his lead in the standing to 12 points over team-mate Rubens Barrichello, fifth today.

The British driver dominated the second half of the race, but he admitted it had not been easy at all.

"This was a tough race for us," said Button. "This weekend we haven't had pace we had in the first three races. These guys have probably gone past us, but the first part of race was very important. I made it work and came out of first corner in third, a tough race."

He added: "For us it is very difficult because of the heat, but this is one of the circuits that isn't really that physical, the engine was a little bit of a worry because the temperature has been very high in qualifying.

"The team has worked so hard. We have had to work doubly hard to get the job done. I am extremely proud of all of them."
