London:
Stefanos Tsitsipas coasted past defending champion Alexander Zverev in straight sets to advance to the last four of the ATP Finals after Rafael Nadal came back from the dead to keep his title hopes alive. The Greek tyro, 21, broke his big-serving German opponent three times in the Group Andre Agassi match to seal a 6-3, 6-2 win and advance to the semi-finals at London's O2 Arena. The straightforward victory, which took Tsitsipas's head-to-head record against Zverev to 4-1, was in sharp contrast to the earlier match, in which Nadal produced an astonishing comeback to beat Daniil Medvedev. The Spaniard was on the brink of defeat when facing a match point at 5-1 down in the deciding set but stormed back to win 6-7 (3/7), 6-3, 7-6 (7/4). "Today is one of those days that one out of 1,000 you win and it happened today," said a delighted Nadal, the top seed in London.
The Spaniard said earning a break back in the deciding set infused him with confidence that he could battle back. "When you have the first break, 5-3, then you are only one break away," he added. "And I know from my personal experience how tough it is to close out matches, especially when you have two breaks in front and you lose the first one. From that moment I thought I can have a chance."
Both players were under intense pressure after losing their opening round-robin matches on Monday Nadal is on a double mission in London -- aiming to win the end-of-season event for the first time in his illustrious career and to secure the year-end number one spot. Russia's Medvedev, who has won two Masters titles this season, took the first set on a tie-break to leave Nadal staring down the barrel. The Spanish veteran broke his 23-year-old opponent in the first game of the second set, repeating the trick to level the match. But Medvedev was quickly into his stride in the decider, sprinting to the net to dispatch a cross-court backhand past his opponent and earn a double break.
Nadal, who came into the tournament under an injury cloud, fended off a match point on his own serve and then, roared on by the crowd, broke Medvedev twice to level. The match went to a tie-break and Medvedev was first to falter, hitting a regulation forehand wide to hand Nadal two match points and he grabbed the opportunity. The Spaniard has qualified 15 straight times for the ATP Finals but has never clinched the title, won a record six times by Roger Federer and five times by Novak Djokovic, who is battling Nadal for the number one ranking.
Tsitsipas pounces
In the later match Tsitsipas grabbed the contest by the scruff of the neck at end of the first set, breaking Zverev in the eighth game and served out for the set. The Greek then broke in the opening game and the fifth game of the second set as Zverev struggled to produce the same level of tennis that helped him beat Nadal on Monday. "I was really surprised by my performance today," said the sixth seed. "I did everything right and once again it was not just me out there but a whole bunch of people, excited people that came to support me. It was a crew situation."
