Alexander Zverev provided a major upset at the Miamo Open Masters when he ousted the top seed and world No3, Stan Wawrinka, out of the tournament in the fourth round.
I felt like he was the one controlling all the points all the time, so I had to change that
The young German teenager, seeded 16, toppled the the tournament favourite and increase his record against the Swiss star to 2-0 to make his first Masters 1000 appearance!
He won 4-6 6-2 6-1 taking full advantage of the opportunities provided by a seemingly tiring opponent whom was celebrating his 32nd birthday.
I had one bad game to start the second set and then it was tough for me, Wawrinka, admitted. I donÈt know. I completely went down physically and mentally, and also my tennis was completely out. I had no more energy.
He added, For sure itÈs a disappointing match. I think the level was quite up and down. We were both fighting a little bit in the first set to find a good level. It was really humid, not easy to play some great tennis.
The 19-year-old victor who saved four of five break points and won 75 percent of his service points, commented: I had to be aggressive. I felt like he was the one controlling all the points all the time, so I had to change that. It worked out well for me..
Roger Federer, Rafael Nadal and Kei Nishikori all advanced to the quarter-finals on expected but Federer, who won the Indian Wells Masters just over a week ago, was tested by the Spaniard Robert Bautista Agut, seeded 14, before emerging the 7-6(5) 7-6(4) winner.
It was a different kind of match, said the in-form Federer, who has also won the Australian Open this year. It wasnÈt the big-serving match where youÈre only going to see so many looks, you know, so when you miss chances you always feel a bit frustrated sometimes.
Reflecting on the match, Federer added: I thought Roberto did a good job of making shots, staying offensive when he could, fending off a lot of good shots that I hit, Then it was tough. The sun was coming from the side in the beginning so itÈs hard to chase the lines.
Nadal beat FranceÈs Nicolas Mahut 6-4 7-6(4) in a tightly fought contest and will face American Jack Sock who comfortably beat his compatriot Jared Donaldson 6-2 6-1.
The Spaniard, chasing his first Miami title, is expecting a tough contest with Sock.
HeÈs a very aggressive player, very powerful player, big serve, big forehand, and a good backhand too. He plays quickly with his backhand.
So I need to play aggressive. ThatÈs the only way. If I let him play in a comfortable position it was going to be impossible for me. So I need focus with my serve, but at the same time I need to be aggressive, said Nadal.
In other matches the Czech Tomas Berdych, the 10th seed, beat FranceÈs Adrian Mannarino 6-3 7-5, while second-seed Nishikori, of Japan, survived second-set scare against Argentine Federico del Bonis before progressing 6-3 4-6 6-3.
Nishikori, who lost to Novak Djokovic in last yearÈs Miami final, will face the unseeded Italian Fabio Fognini, who defeated American Donald Young 6-0 6-4.
Nick Kyrgios, seeded 12, is also through following his 7-6(5) 6-3 win over BelgiumÈs David Goffin and will face Alexander Zverev in what should be an intriguing match between the two young stars.
