Roger Federer saves two match points to book semifinal place — ATP Miami

Nick Kyrgios held off Alexander Zverev in a fascinating quarter-final clash to set up a final-four showdown with former world number one Roger Federer at the Miami Open.

Australian Open champion Federer, who also won at Indian Wells two weeks ago, is playing some of the best tennis of his career and appears completely recovered from a knee injury that kept him out of the second half of previous year.

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

Earlier, the Swiss looked set for another emphatic victory after taking the first set.

Top seed Stan Wawrinka crashed out of tennis' 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.

Yet even in that moment, Federer still felt some hope.

After bowing out of Australian Open as early as in the second round, the 21-year-old has been reaching final stages of all the tournaments he has featured in. If you choose the option that says "Miami Open - Stadium (Quarterfinals)" on ESPN 3, you only have to log in to your internet provider-rather than a pay TV provider-to watch a live stream of the match. She won the first three games of the second set - with Pliskova giving her racket a toss afterward - and then controlled the rest of the match.

But Berdych regrouped impressively in the second set and made the most of a loose Federer service game to go 5-3 ahead - the first time in 15 successive sets between the pair that he had taken one from the Swiss player.

Just as in his lone loss of the year in Dubai to Evgeny Donskoy, Federer was unable to shut the door with a 5-2 lead in the third and an eventual match point en route to a deciding tiebreaker.

Kyrgios - into his third semi-final of the year - now has the chance to lock horns with 18-time grand-slam champion Federer after food poising forced him to withdraw from their quarter-final contest at Indian Wells last week. A double fault from Berdych at 6/7 wrapped up the match after one hour and 57 minutes.

Tomas Berdych almost had the contest won.

"Sick atmosphere", Federer told the crowd afterward. "But they seem to be working now".

"I enjoy winning breakers because those are the ones that are going to make you win a tournament or not sometimes", he said.

Federer has not tasted success in Miami since 2006, when he completed the Indian Wells-Miami title double for the second consecutive year.
