Miami Open: Roger Federer to battle it out with Rafael Nadal in final

Roger Federer beat Australia's Nick Kyrgios 7-6 (11/9), 6-7 (9/11), 7-6 (7/5) to set up a mouth-watering Miami Open final against Rafael Nadal.

Federer and Kyrgios produced an extraordinary range of shots in an enthralling, fiercely intense semi-final that kept a capacity crowd at Key Biscayne on the edge of their seats.

When Federer won the third tie-break a furious Kyrgios hammered his racket into the ground three times as the frustration of a remarkable near-miss came flooding out.

Kyrgios broke in the first set to go 4-3 up but Federer, with the loud crowd behind him, broke back to level at 5-5 when the Australian missed with an attempted big return.

The big-hitting Kyrgios was frequently booed by the crowd for racquet throwing and language -- and sometimes for very little -- but appeared to be enjoying the role of pantomime villain.

The first set tie-break was a gripping affair with the Australian twice having set point before it was decided when his return went wide. The boos rang out again as he hurled his racquet in frustration.

The serve dominated more in the second set and with neither player able to break another tie-break was needed. Federer had match-point at 8-7 but found the net with his return.

Kyrgios finally won the battle with an amazing cross-court return to go 10-9 up, then followed it up with a thundering ace to force a third set.

There was nothing to choose between the pair in a third set that went to yet another tie-break.

Kyrgios was furious when a fan called out during one point, and Federer enjoyed two successful challenges late on his way to a win that sent the crowd wild with delight as Kyrgios went wild with rage.

There was little drama in Nadal's 6-1, 7-5 win over Italian Fabio Fognini.

The unseeded Fognini struggled to get going in the first set which was dominated by fifth-seeded Nadal and over with in 25 minutes.

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 will play in his fifth Miami final but will be looking for his first title in the Masters series event.

"I think I played a very good first set," Nadal said. "He had mistakes obviously. In the second, it was not about losing concentration, it's about not being lucky at the beginning of the second set.

"Normally I would have a break at the beginning of the second. I had so many chances and then situation changes. When you don't convert opportunities you're in trouble, and that's what happened," he said.

Federer beat Nadal in an Australian Open final thriller in January to claim an 18th Grand Slam title and he swept past Nadal in straight sets in the fourth round at Indian Wells en route to the title there.

"If it's Roger, going to be another one for both of us, and that's it. Just another one," Nadal said of another instalment in their long-running rivalry.
