She even made a nervy opening to the match throwing three double faults in her opening service game.

"It was first time for me to play not only for the Grand Slam, but it's also for No.1 spot. And I have never been through this situation, but she has already done that," said Safina, who was playing in just her second Grand Slam final after finishing runner- up at Roland Garros last year.

The 22-year-old Russian looked rejuvenated at the start of the second set, breaking Williams' first serve to build up a 2-0 lead, only for the American to break back twice to sail through at 6-3.

Williams looked in complete control, hitting only seven unforced errors to 21 from the Russian.

"I thought Dinara was really doing pretty good, hanging in there. She never gives up. She's always fighting till the last point," Williams said.

"I definitely think it was definitely one of my most dominant performances, especially considering it was a final. I was able to just lift the level of my game in the final," she added.
