Wozniacki into Miami Open semis, Federer books q-final place

Federer said. "For me, it's hard to say yes to that question".

"I definitely got very lucky at the end, but I think I showed great heart today".

Top seed Stan Wawrinka crashed out of the Miami Open on Tuesday falling 4-6, 6-2, 6-1 to German young gun Alexander Zverev, who booked his first Masters 1000 quarter-final.

The last of the quarter-finals at the ATP World Tour Masters 1000 event pits Australian No.12 seed Nick Kyrgios against German No.16 seed Alexander Zverev, with the victor earning a semi-final showdown with Federer.

A finalist will be decided between Federer and Kyrgios, who will face the victor of Friday's game between Spanish Rafael Nadal and Italian Fabio Fognini.

He ripped through the field at Indian Wells without dropping a set en route to the title, and has not lost a set in his first two matches in Miami either.

Despite signs of frustration from the players during the tense final set, which included both chastising the chair umpire and lines judges, Kyrgios appeared to appreciate the Zverev challenge.

Kerber took charge early, breaking twice to establish a 4-1 lead and she was in firm control from then on.

But then, the Czech dug deep and came out fighting.

A straight sets win looked on the cards, but Zverev raised his game and saved three match points in the second-set tiebreak, only for the Australian to bounce back strongly to take the decider.

It was the second demoralizing defeat this month for Berdych. Three Americans left in the draw, including a highly ranked Jack Sock, and unseeded Donald Young and Jared Donaldson all have matches in the Grandstand as well, starting at 10:50 a.m.

I'm happy we get this match after being robbed of it a couple of weeks ago when Kyrgios withdrew due to food poisoning. Should I destroy the table? "I had no more gas", said Wawrinka.

"It s obviously not something that you want, to finish the tournament like that". I know that I can't bring 75 or 80 per cent of my game. "It s going to be fine".

The Kyrgios-Zverev quarter-final was billed as a glimpse at the future of top-level tennis and if so, the sport should have an entertaining era ahead. Kyrgios leads the FedEx ATPHead2Head with Federer 1-0, prevailing on the clay courts of Madrid in 2015 in a third-set tie-break.
