Miami Open: Federer, Kyrgios Battle into Semifinals

Asked if this was the best he had ever played, 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".

The Argentine had a chance to turn things around when he had a break point when down 4-3 in the second set but Federer, moving well and looking full of confidence, held firm and wrapped up the match in one hour and 22 minutes.

Federer next will play the victor of Thursday s later quarter-final between two of the ATP s up and coming stars, Australia s Nick Kyrgios and Germany s Alexander Zverev.

Roger Federer's resurgence has continued after he battled his way past Roberto Bautista Agut to reach the quarter-finals of the Miami Open.

Men's storylines: The bottom quarter a few weeks ago at Indian Wells was historically loaded with Federer and Nadal collided in the fourth round.

Kyrgios ground out victory after an enthralling second-set tiebreak.

But by the end of the non-contest, Federer's serve unbroken, a loud chant of "Let's go, Roger" rang out around the old court.

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

Having taken the first set, Wawrinka looked comfortable, but the German made a sublime recovery to secure his place in the next round 4-6, 6-2, 6-1.

In the tiebreak, Berdych hit a backhand victor into the corner to set up two match points, the first on serve, but netted a forehand to squander the first.

Williams struggled with her first serve and saved five break points early in the second set before breaking Konta to take a 3-1 lead. In the second set breaker it was the Swiss superstar taking the initiative, claiming a mini-break on the first point before sealing a second later on to go up 6-2. 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". He won the title in 2005 and 2006.

The fifth seed will play the victor of the evening quarter-final between 16th seed Alexander Zverev and 12th seed Nick Kyrgios.

As for women, in the first semifinal, Caroline Wozniacki will try to reach her third final this year after Doha and Dubai against the World No. 3 Karolina Pliskova, who beat her for the first time on four matches played in total last month in Qatar in the final.
