Federer saves match points to beat Berdych in Miami quarter-final

Yet with two match points, Berdych cracked, Federer winning the next three, with victory wrapped up through a double-fault from an opponent who will yet again wonder what might have been.

Nick Kyrgios is determined to make the most of his Miami Open semi-final clash against Roger Federer, who he described as the "greatest of all time". But playing against Federer will be be a very, very hard and Berdych is not expected to win. Then you see how much I'm frustrated.

Federer, continuing his flawless tennis of late, cruised in the first set but grew bored in the second set, allowing Berdych to snap a 15-set losing streak to his longtime rival.

Federer will face Nick Kyrgios in the semi-finals after the Australian came through an entertaining 6-4, 6-7 (9/11), 6-3 victory over 19-year-old German Alexander Zverev.

Already 4-2 up in the first set, Federer only needed the first of two break points to widen his advantage over the experienced Czech.

Kyrgios also hit 34 winners to 21, including a between-the-legs shot to win a point in the opening game of the second set. "But I think I showed great heart today".

Still clearly aggravated by the decision, Zverev lost his concentration and way as Kyrgios booked a spot in the semis, despite fending off another two match points.

But now they were as silent as the giant iguana that roamed Court 1 last week, holding their collective breaths, anticipating one of Berdych's 136-mph serves to send the resurgent 35-year-old Swiss legend and his growing brood packing.

Federer gets a day off and will meet 10th-seeded Tomas Berdych - who defeated Adrian Mannarino of France 6-3 7-5 - in the quarters.

"That was the best match she played against me, " said Pliskova, 1-4 against Wozniacki, including a win in the Doha finals last month.

The crowd at Crandon Park Tennis Center certainly enjoyed Federer's deft touch, while Berdych could only watch on in disbelief.

But he held on, joining Rafael Nadal and Fabio Fognini in the semifinals.

Nishikori - a finalist at Key Biscayne a year ago - rallied from a break down in the final set to beat Federico Delbonis 6-3 4-6 6-3.
