Rafa Nadal rolled by unseeded Italian Fabio Fognini 6-1 7-5 on Friday to reach his fifth Miami Open final and set up a rematch of the Australian Open decider with Roger Federer.
When it comes to getting into contention for the top ranking, the Miami Masters final is very important for both Federer and Nadal.
It was a bitter test of nerves and precision marksmanship in which 35-year-old Federer showed greater reserves of mental strength and stamina than his 21-year-old rival.
When Federer hit a service victor on the final point, Kyrgios angrily whacked his racket three times against the hard court. "I'll be ready on Sunday", said Federer.
The two played a good match, which went down to the wire.
The Swiss, who has won two of his last three tournaments including the Australian Open, had to dig deep to get through a second straight test after fending off a match point in his quarter-final victory over Tomas Berdych. Last year I had really bad injury at the beginning of the year. "It's always been a tournament where I wouldn't say I struggle, but I've just not had the results I wanted". His serve is less explosive than that of Kyrgios, but Federer is much better at backing it up with objective. "He's a big challenge for me, and I think for everybody". "I thought the crowd would have enjoyed it".
What have they been saying?
The pair contested three tie-break sets before Federer eventually prevailed by a 7-6 6-7 7-6 scoreline to set up a showdown with Rafael Nadal. "I give him a present of the first set". He didn't face a break point in the final two sets.
There was nothing to choose between the pair in a third set that went to yet another tie-break.
Sympathetic to Kyrgios' situation, Federer waited until Kyrgios began walking to the net to shake hands before celebrating by clubbing a ball into the stands. The 12th-seeded Wozniacki, a part-time South Florida resident, made the women's final for the first time in 10 tries by topping second-seeded Karolina Pliskova 5-7, 6-1, 6-1.
The Italian, who indicated he had some trouble with his elbow, put up a better response in the second but his work was undone when he double-faulted on break point, leaving the Spaniard to serve out for the win.
Nadal, who is still searching for a breakthrough Miami trophy, will be competing in his fifth final at the event.
"I had some ups and downs, bit of a rollercoaster", said Kyrgios. "He had mistakes obviously".
Federer edged to 6-5 and then 7-6 before having to save two set points of his own, the second when he drove an imperious forehand home after opening up the court.
