NOVAK Djokovic has been preparing for his final four confrontation with Kevin Anderson in the final ATP in an incredible fashion by Marin Cilic 7-6 (9/7), 6-2 as Alexander Zverev in trying to face Roger Federer.
Serbian's world number started with an evening at O2 Arena in London, with the luxury knowing that he had already qualified as the winner of the Guga Kuerten Group but he looked suddenly and focused on the first point.
Earlier, Zverev off John Isner 7-6 (7/5), 6-3 to reach the finals of the season term for the first time, making the final Djokovic-Federer dream remains a possibility.
Djokovic, all dressed in black, won 31 incredible points on serving him from the third game of the first set until the fourth game of the second against Cilic, who could not even move forward with a victory.
"Obviously, I knew before the game I had already applied, and I know who I'm playing, so it was not easy to go to # 39; This game with 100 percent of readiness to win, "said Djokovic.
"But this is a unique format and we both wanted to win from the first point, it was a first first game that had probably decided on the game.
"(Anderson) plays a great tennis, he definitely is in his best season and continues to do so throughout this tournament. He plays well, serves & # 39; n good, very aggressive, so I know what to expect. "
In a high quality competition, the Grand Slam 14 champion waited quietly to save a specific point at the first set break before taking 9-7 at his second specific point.
In the second set, Djokovic immediately gives Cilic under severe pressure. The US Champion of the Croatians was deep to stay in the competition in the early stages, but he crashed in the fifth game, giving a mountain to climb himself and also hiding in his next service game, leaving Djokovic to serve for the victory.
Djokovic, who has not reduced a single set in his three-round robin games in London, has enjoyed a wonderful revival in the second half of the season after penelin surgery and an adverse form earlier in the year.
It has lost only two games since the beginning of July, winning the US Wimbledon and Open along the way and again emerged as the man to beat as he tried to pull a level with Federer on six final titles ATP.
ZVEREV IS SETS UP UP FASH CLASH
Zverev was aware that winning from any scoring line against the American giant Isner would take her to the final.
The turning point came at the end of the 12th game, when the German 21-year-old saved a point set alone serving with an ace, going on to force a break, which won.
In the second set, he had one break of service in the eighth game and Zverev went out for the win.
"It's clear that the quarterly rounds are great," he said. "But the tournament is not over. I'm in the semi-finals. Only good opponents are left. Only the best in the world is available.
"I'll play Roger tomorrow, which will be very difficult but hopefully, it's very nice. We'll see how much I can go." The third Zverev seed, trained by Ivan Lendl, is the youngest final in the ATP Finals since Juan Martin del Potro in 2009.
Secondly, Federer, tracking his 100th title, beat Anderson in a quick set to the top of the Lleyton Group Hewitt, but both players moved, leading to early departures to Kei Nishikori and Dominic Thiem.
