'No way': Commentators in disbelief over 'ridiculous' Rafa Nadal moment

Rafael Nadal and Novak Djokovic have continued their battle for the year-end World No.1 ranking, both players reaching the Paris Masters quarter-finals with wins over Stan Wawrinka and Kyle Edmund respectively.

The 33-year-old Nadal is already guaranteed to usurp Djokovic at the rankings summit next week, but winning a maiden Bercy title would also secure the year-end top spot before next month's ATP Tour Finals in London.

He produced an impressive display to take his career head-to-head record against three-time grand slam champion Wawrinka to 19-3 with a clinical 6-4, 6-4 victory.

And one winner in the second set had fans and commentators in awe.

Wawrinka appeared destined to win the rally, running Nadal all over the court before hitting what should have been a put-away smash.

However Nadal predicted where Wawrinka’s ball was heading, racing to his left before unleashing a stunning forehand winner down the line.

Wawrinka could only look on in stunned silence as fans rose to their feet with applause.

“No way,” one commentator said on Tennis TV. “That is ridiculous from Rafa Nadal.”

The official Tennis TV Twitter account posted the video, writing: “How does he do it? Incredible.”

And they weren’t alone.

Djokovic had earlier booked his last-eight place with a 7-6 (9/7), 6-1 win over Britain's Edmund.

Nadal has never won the Paris Masters or the ATP Finals and only two of his 84 titles have come indoors.

"That's the beautiful thing about this sport, (to) have the capacity to adapt yourself to the different conditions," said the 12-time French Open winner, who called the doctor onto the court in the second set to help deal with a stomach problem.

Nadal will face 2008 champion J-Wilfried Tsonga in the quarter-finals after the French wildcard saved two match points to edge out Germany's Jan-Lennard Struff 2-6, 6-4, 7-6 (8/6).

"I have a match against a player that is playing well," said Nadal.

"I need to do a lot of things well, but I hope to be ready to make that happen."

Djokovic to face Tsitsipas

Top seed Djokovic needed seven set points in the first set before beating Edmund with relative comfort by racing through the second to make his eighth quarter-final in the tournament.

"I was feeling energy-wise better and felt more alert, just more strength, more energy, more speed," said the 32-year-old, who has been struggling with illness this week.

The 16-time grand slam title-winner is chasing a record-extending fifth Bercy crown and will next face World No.7 Stefanos Tsitsipas, who beat Alex de Minaur 6-3, 6-4.

The 21-year-old Tsitsipas leads his head-to-head with Djokovic 2-1, after victories at the Shanghai Masters earlier this month and the 2018 Canadian Open.

"He (Tsitsipas) is one of the best players in the world," said Djokovic. "He's already (an) established player."

Djokovic is hoping to tie Pete Sampras' record of finishing six years as the world's best player, while Nadal is looking to achieve the feat for a fifth time.
