Novak Djokovic reaches out to return a shot to Roger Federer, who won the semifinal.

NEW YORK — Ominous clouds overhead, the sort of hard court that troubled him this season underfoot, Roger Federer sensed something Saturday he hadn't in quite a while.

He was playing exactly like that guy named Roger Federer.

The Federer who has won 33 consecutive matches and four consecutive championships at the U.S. Open. The Federer closing in on his 13th Grand Slam title.

"One more match," he said, "is all I need."

Only after Federer finished restoring order to his world by dismissing Novak Djokovic 6-3, 5-7, 7-5, 6-2 did Tropical Storm Hanna carry chaos to Flushing Meadows, dumping enough rain to suspend the other men's semifinal in progress and postpone the women's final.

So Serena Williams will seek her third U.S. Open and ninth major title against first-time Grand Slam finalist Jelena Jankovic tonight.

The men's final was delayed until Monday for the first time since 1987, giving Federer plenty of time to rest. He also was going to be able to do some scouting today when his nemesis, new No. 1 Rafael Nadal, was to resume his semifinal against No. 6 Andy Murray. They stopped Saturday with Murray leading 6-2, 7-6 (5), 2-3.

The winner will face a Federer who looked confident and supremely competent against Djokovic in their rematch of the 2007 final.

"I had moments out there where I really felt, 'This is how I normally play on hard court' — half-volleys, passing shots, good serving, putting the pressure on, playing with the wind, using it to my advantage," said Federer, who produced 20 aces and only one double-fault.

"I definitely had moments during today where I thought, 'This is how I would like to play every time.' So it was a very nice feeling, actually, to get that feeling back."

He dominated the opening set and the last 1 1/2 sets to reach his 13th final in the past 14 Grand Slam tournaments.

The one gap in that span was the Australian Open in January, when Djokovic upset Federer in the semifinals en route to his only major title. Perhaps that gave Federer extra motivation. This was hanging in the balance, too: Had Djokovic won Saturday and gone on to win the championship, he would have surpassed Federer in the rankings, dropping the longtime No. 1 all the way to No. 3.

"This was a big match. I knew it from when I saw the draw," said Federer, who called his pursuit of Pete Sampras' record of 14 career major championships "obviously still very much alive and everything is possible."

Also in his sights: Federer can become the first man since Bill Tilden in the 1920s to win five consecutive U.S. tennis championships.

The fans in Arthur Ashe Stadium cheered for both the second-seeded Federer of Switzerland, and the third-seeded Djokovic of Serbia, but the reigning champion got more backing.

"I feel a little bit New Yorker right now," Federer said. "I definitely appreciate the efforts from the fans, supporting me and pushing me forward."

Maybe they remembered what happened Thursday on the same court. After beating Andy Roddick in the quarterfinals, Djokovic drew merciless boos by lashing out at the American, taking him to task for making light of the Serb's series of medical issues earlier in the week.

"It's been a very exhausting tournament, mentally and physically, for me," Djokovic said Saturday, declining to discuss the Roddick matter.
