Nadal holds off rising talent...

our sport and the present too,” said Nadal, who reached the fourth round for the 10th time in 12 appearances at Melbourne Park.

“Today was a great battle, I am very happy to be through. It was an important result for me as I’ve lost my last couple of matches in the fifth.”

Returning to Melbourne Park as ninth seed after curtailing his 2016 season because of injury, Nadal will next face Gael Monfils of France as he bids for a 15th grand slam title.

While Zverev’s performance reinforced his position in the vanguard of generation next, Nadal confirmed that he is healthy enough to take advantage of the early exit of 2016 champion Novak Djokovic from his half of the draw.

It was the younger man, however, who got off to the quicker start, grabbing a break in the opening game with a sumptuous backhand dropshot and moving the former world number one around the court.

Zverev had a 20 kph advantage over Nadal on first serve but the German was unable to dominate in the second set the way he did in the first and a single break evened up the contest.

The third set developed into a ding-dong battle with neither player able to snare a single break point and it was Zverev who edged the tiebreak with an angled winner, again off his backhand.

Nadal grabbed the only break of the fourth set on Zverev’s first service game and tied the contest up with his eighth ace, sending it into a decider.

Another early break for Nadal appeared to set him on the path to victory but Zverev was having none of it and broke back, only fading when he started Rafael Nadal

cramping after a series of marathon rallies to allow the Spaniard to claim the victory.

“I’m disappointed but I know that this was a great match, That was a great fight. There’s a lot of positives in this match,” Zverev said.

“I think he’s probably one of the fittest tennis players in the history of the game. Obviously I wanted to win. I could have won. It’s disappointing.”
