Zverev is simply playing with great confidence right now and no longer has the dips in his game that he had last season.
"This one against Roger is something so special for me because he was always a great idol growing up for me", Zverev said. "Of course, two "masters" - anyone would be proud of this achievement and nobody could expect", said Zverev after the match. Then I started this year winning back-to-back matches against really good players.
Federer hammered five aces, made just two double faults and won 81 percent of his first serve points in the 68-minute centre court match. There were some opportunities for Federer too, especially at the start of the second set.
Federer, 36, lost for just the third time in 38 matches this year.
Zverev, who triumphed in Washington last week, kept Federer at bay early in the first set before he found the break he needed to edge in front.
With a yet another comfortable victory in the tournament, Roger Federer extended his winning streak to 16 matches, a record he had scripted back in 2012.
Federer, who dropped to 5-1 in finals in 2017, is undergoing a resurgence this season after it appeared to many he might be slowing down as he transitions through his mid-30s. At the 2014 Rogers Cup, he lost 6-2, 6-0.
"I'm sorry that you didn't win Montreal this year", says Zverev. "I got some decent rhythm going".
The Swiss Maestro is in the Cincinnati draw as the No. 2 seed in the tournament.
He said he will "take a decision in the next couple of days" whether he plays in Cincinnati, where he has a first-round bye.
On the other hand, if the Swiss win, we will see him for the first time at the head of the rankings since 4th of November of 2012. The young German with Russian origins is slowly starting to make his way to the top, and we can expect that maybe even during the next year, we can have new Grand Slam champion.
"I mean, I go from being not known to being so known in the tennis world, in Canada in general".
Federer was hoping to add another milestone to his memorable season but he failed to post his 94th career title which would have moved him into a tie for second all-time with Ivan Lendl.
