Federer ready for Isner shoot-out for Miami crown

Roger Federer is gearing up for a Miami Open final shootout with John Isner on Sunday after blowing away young-gun Denis Shapovalov in straight sets.

Federer produced a 6-2, 6-4 masterclass at Hard Rock Stadium to leave up-and-coming star Shapovalov, who grew up idolizing the Swiss, chasing shadows during a difficult first set.

The Swiss was superb in dismantling the 19 year-old's game, but knows with huge serving Isner lying in wait in what will be the former world number one's 50th ATP Masters final, the key will be to defuse the reigning Miami Open champion's monster service game.

Isner used it to great effect in his 7-6 (7/3), 7-6 (7/4) win over Shapovalov's friend and compatriot Felix Auger-Aliassime earlier in the day, smashing down 21 aces. He'll be looking for more of the same against 20 time Grand Slam champion Federer.

"Playing a big server like John is like being in a penalty shootout in soccer, but I enjoy it," said number four seed Federer who coped brilliantly with Kevin Anderson's dangerous serve in the quarter-finals, winning the first set to love.

"Sometimes you go with momentum. Sometimes you go with feel. Sometimes you guess maybe a little bit and sometimes you see it. It's a combination of all sort of things.

"You just hope that the stars align, that you pick the right side, that he picks the wrong side, that maybe he misses a serve, that you can put him in uncomfortable situations time and time again, and at the end somehow you find a way."
"I was just trying to play as good as I can, but he played an excellent match. I wasn't able stay at his level. I'm just going to try to learn from this and move forward."
"I had to because when you let Denis play, he's got some serious power and he gets rhythm going. He can really put you in uncomfortable situations."
"Unusual," Isner called it. "It could have been a little bit of inexperience and maybe a little bit of fatigue, also."
