"I would lie if I say I didn't think I'm going to lose," Djokovic said.
Might as well go down swinging then, right?
He turned violently on a wide, 108 mph serve from Roger Federer for a cross-court, forehand winner that barely nicked the line. The fans in Arthur Ashe Stadium, ready to explode for a Federer victory, instead found themselves taking a cue from Djokovic — who raised his hands, asking them to pump up the volume, and give him a little more love.
About 10 minutes later, those same fans were dancing with Djokovic as he boogied at centre court to celebrate an epic U.S. Open semifinal win — one in which he dug out of a two-set hole, then saved two match points to beat Federer for the second straight year.
Top-seeded Djokovic won 6-7 (7), 4-6, 6-3, 6-2, 7-5 Saturday to improve to 63-2 on the year. This was only his second career comeback from two sets down, while Federer lost a two-set lead for the second time in three months after going 178-0 lifetime before this year's Wimbledon quarterfinals.
Next, Djokovic will face defending champion Rafael Nadal in a rematch of last year's final. No. 2 Nadal beat No. 4 Andy Murray 6-4, 6-2, 3-6, 6-2 in the later semifinal. Djokovic is 5-0 against Nadal this year. All the meetings have been in tournament finals, including Wimbledon.
"I didn't find the solution yet. I will try my best," Nadal said. "I play last year's final against him. I think I played a fantastic match. I will try the same."
Nadal's four-set win over Djokovic last year made him the fourth man to win three Grand Slam titles in a year since the start of the Open era. Djokovic could become the fifth, though he said regardless of what happens, the comeback win over Federer will always stand out.
"It was definitely the biggest win of this year, one of the biggest wins of the career under the circumstances," Djokovic said. "Roger was in control, playing better. I switched gears and played much better over three sets."
So much better, in fact, that after the fourth set, the prospect of third-seeded Federer ever getting a match point seemed bleak.
Djokovic, who spent the first two sets shaking his head, commiserating with the folks in his players box, even folding his hands in mock prayer, turned things around suddenly and unexpectedly.
He got an early break in the third to capture the momentum.
After winning that one, he placed 16-of-20 of his first serves in during the fourth set and tore off his first 15 service points to easily push the match to the distance.
The fifth-set end-game started with Djokovic serving at 3-4 and stringing together an uncharacteristically bad game, getting broken at love on two mishit forehands, a framer of Federer's that set up a winner and a double fault on a second serve that missed the line by about a foot.
After missing a backhand to open his service game at 5-3, Federer hit three straight serves Djokovic couldn't get back. That gave him two match points, same as he had last year against Djokovic in the semifinals, and the fans were squarely on his side, as he stood oh-so-close to making his 24th Grand Slam final and moving a win away from adding to his record 16 Grand Slam titles.
But Djokovic isn't putting together one of the greatest seasons in tennis history for nothing.
"The forehand return, I cannot explain to you because I don't know how it happened," he said. "I read his serve and I was on the ball and I had to hit it hard, and it got in, luckily for me."
On the second match point, Federer's serve hit the back of the line and jammed Djokovic, but somehow he got it back. Federer moved in and cranked a forehand, but it ticked the net and ricocheted out. Federer sprayed a forehand wide at deuce and suddenly, a crowd gearing for a Federer win was shouting "No-vak! No-vak! No-vak!"
Djokovic said it was no insult that the fans had been behind Federer, who makes some kind of history seemingly every time he steps on a court.
Still, the current world No. 1 wasn't giving up on capturing their hearts. Which was why he made a scene between the match points — an awkward time for showmanship, though one Federer said he had no problem with.
"At that stage, you're trying to get as much support as you can," Djokovic said. "You're trying to get energy."
Stoked with that energy, Djokovic won the last four games and, counting the two match points he saved, he took 17 of the final 21 points.
Federer was among the 22,000-plus on an 27-C day in the stadium who couldn't believe how Djokovic saved the first match point. He said Djokovic is the best version of the kind of players he faced as a kid — who start taking huge chances when they feel they have nothing else to lose.
"Then to lose against someone like that, it's very disappointing, because you feel like he was mentally out of it already," Federer said. "Just gets the lucky shot at the end, and off you go."
Thanks to the rain that scrubbed two days of play from this tournament, Djokovic and Nadal will get a day's rest between the semifinal and the Monday final, a break from the long U.S. Open tradition of closing things out on back-to-back days on the weekend.
Fittingly, given how things have gone lately, the start of the Federer-Djokovic semifinal was delayed for about an hour because showers began falling shortly before the players were supposed to walk on court, which had "9-11/01" painted in white to commemorate the 10th anniversary of the Sept. 11 attacks.
That made it an even longer wait for the headliners of the night session, Serena Williams and Caroline Wozniacki, who were scheduled for the featured women's semifinal. In the other women's semifinal, No. 9 Sam Stosur defeated Angelique Kerber 6-3, 2-6, 6-2 on the Grandstand Court.
Meanwhile, Djokovic avenged one of his only two losses this season. He fell to Federer in the French Open to snap a string of 43 straight victories — the third-longest win streak in the Open era.
Federer, meanwhile, was trying to win at least one Grand Slam tournament for the ninth straight season and appeared more than ready to grab this one.
Shortly after closing out a 9-7 first-set tiebreaker by hitting a massive, unreturnable backhand into the corner, Federer broke Djokovic twice in the second and was practically bouncing from point to point while Djokovic slumped his shoulders.
Djokovic began his rally by serving out the first game of the third set at love, then breaking Federer after five deuces.
He turned into a steamroller over the next hour and there was no avoiding the sense that a shift of power was being completed — from Federer, who won three Grand Slam tournaments each in 2004, 2006 and 2007, to Djokovic, who is trying to do it this year, along with Nadal, who is still very much in that mix.
Nadal and Djokovic will meet for the third time over the last five Grand Slam finals.
But even with the loss, Federer showed he's not done.
To move within a point of the match after the way Djokovic played was a testament to what the 30-year-old still has left in the tank.
"I did all the right things in so many tournaments," Federer said. "But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know."
