EPA/ANDRE PICHETTESloane Stephens of the United States of America in action against Caroline Wozniacki of Denmark during the semi-finals of the Rogers Cup Women's Tennis tournament in Toronto, Canada, 12 August 2017. Both men have been playing well on their way to the last four.
"That's also reasons why I'm still playing today". The pair met in a Davis Cup World Group play-off in 2012 with Federer winning 6-1, 6-4, 6-4.
Federer added that for Shapovalov to be knocking on the door of a final at his age puts him in some elite company.
"I guess this is where my experience kicks in", said Federer.
In the semi-final on Saturday, Haase will face the victor of the clash between Switzerland's Roger Federer, second seeded, and the Spanish Roberto Bautista Agut, ranked 12th. It appears to have been taken at the Rogers Cup nine years ago, when Shapovalov, in the red baseball cap, was nine years old.
The unseeded Monfils played his third straight three-set match, including an upset win over fifth-seeded Kei Nishikori in the second round. Thursday was their first matchup in three years. He managed to avoid that fate, holding serve to make it 5-1.
Federer will face Spain's David Ferrer in the third round. He recovered a the break quickly and earned himself a triple-break point with Zverev serving at 3-4 in the second set.
Shapovalov said he didn't think he had a chance to win at all before the match. The Spaniard's challenge faded thereafter, and Federer took the decider 6-2. He broke serve. He had huge holds. An early break in the second proved fatal for the Spaniard. There he came up against 7th seed Grigor Dimitrov. Haase won it comfortably 6-1 to progress into the quarterfinals.
Schwartzman was dejected after being outplayed in the final two sets. Haase had to muscle his way through his last two matches and is coming off a match in which he won 46 percent of his return points.
How do they match up?
If Federer can defeat Haase, he'll be on track to capture his sixth singles title of the year and lock up the No. 1 seed at the U.S. Open, with Andy Murray injured and Novak Djokovic out for the remainder of the season. This doubles ability is reflected in his excellent hands at the net.
Shapovalov will now be ranked 67th in the world when the new list comes out.
"I didn't even know if I could ever play tennis again", Haase said. Federer has won 15 straight matches on hard court. Nor does he have the defensive skills to survive the onslaught Federer will throw at him. "A bit surprising, to be quite honest, because I hadn't practiced much". You just expect that in a finals like this.
