MASON, Ohio — Roger Federer is back in top-of-the-world form heading into the U.S. Open.

The Swiss star played up to his No. 1 ranking Sunday, beating Novak Djokovic 6-1, 7-5 for the Cincinnati Masters title and plenty of confidence heading into the Open, which he has won each of the last five years.

Federer's goal in Cincinnati was to work off the rust from a brief layoff during his stellar season. He won his first French Open championship and an epic Wimbledon match against Andy Roddick for his record 15th Grand Slam title, then took time off to become the father of twin daughters.

He dominated at the outset against Djokovic, who hadn't dropped a set all week.
