Shapovalov beat Nadal 3-6, 6-4,7-6 to advance to the quarterfinals where he will take on Adrian Mannarino from France.
Federer responded quickly in the second set, going a break up to lead 3-2 before holding for a 4-2 lead. "I remember when he was injured previous year, and here he is a few matches away from clinching world No 1". He's nearly always done the heavy lifting of his year in the first half. But you could tell why he has won so many Grand Slams.
Speaking with media afterwards, Nadal was unhappy with the way he played while giving credit to Shapovalov for his resolve during the big moments of the match. "They were cheering so loud, it was insane". "Guys I'm used to playing, if I hit really hard, they'll kind of block it but he's constantly moving forward like a freight train".
Roger Federer eased back into action for the first time since winning his eighth Wimbledon title last month as he also reached the third round with a dominant victory over Canada's World No. 116 Peter Polansky 6-2, 6-1. Seventeen is a lot. The players then held serve throughout the set to force a deciding tiebreaker. He's a great fighter on the court.

Federer was more aggressive in the second set.
With Federer slowly improving his first serve as the match wore on, Ferrer was unable to carve out the break opportunities he had found in the first set.
Nadal, 31, was pressing on Shapovalov's serve throughout the third set but the Canadian saved each of the Spaniard's six break points to force a tie-break. Federer controlled matters from that point.
Federer is through to the Rogers Cup quarter-finals after a 2-1 victory over David Ferrer despite losing the first set, although he can not claim the world number one place until Cincinnati.

The Richmond Hill, Ont. native has been touted as the next big thing in Canadian tennis and it appears that he is ready to make a name for himself.
Speaking after the 3-6 6-4 7-6 (6-4) upset, Nadal said: 'It's my worst loss of the year because it's my loss to the opponent with the lowest ranking and because I had the chance to be world number one. It was the Frenchman's first win in four meetings with Nishikori.
Polansky never looked comfortable after he double faulted twice in his first service game and had difficulty handling Federer's pinpoint serves.
