Nadal misses chance to become world No.1 after Rogers Cup defeat

Meanwhile, Federer's arch nemeses Rafael Nadal suffered a shock exit later in the day as he went down against unheralded Denis Shapovalov. Nevertheless, the rockets he fired kept flying true and landing for glowing winners.

Q. Are you a little bit surprised at 18 years old he didn't crack? Nadal would have returned to No. 1 if he had made it to the semifinals. It was an utterly unexpected result, and Shapovalov reacted exactly the same way all kids his age do after accomplishing something of that magnitude. "Not [just] me", Shapovalov said during last year's Rogers Cup. Shapovalov is now ranked #143 and was given a wildcard into the event.

Fourth seed Alexander Zverev saved three match points - one of them after a 49-shot rally - before beating Richard Gasquet 6-3 4-6 7-6 (7/3).

Monfils trailed 2-6 in the third-set tiebreaker, which gave the Japanese star a quadruple match point.

"He's my idol", Shapovalov said of Del Potro.

RAFAEL NADAL: No. He has nothing to lose.

Juan Martin del Potro was eliminated by a Canadian wild card Denis Shapovalov, who is only 18 years old. His lefty serve was effective against his fellow southpaw, brutally so at times.

Shapovalov continued to go toe-to-toe with Nadal until the decisive tiebreak, where the Spaniard appeared set to book his spot in the next round, only for the former to come storming back. "Big mistake with my backhand with the 3-Love". That's an easy task to set, but a hard one to execute. Instead of waiting to be rescued, he pulled himself out hand-over-hand. The outburst appeared to steady the Swiss, whose serve and overall accuracy improved as the two-hour match progressed. Federer said if it's a two-way race between Rafa and him and he hopes to be him as it means a lot of him to get back at No 1. I have another week in Cincinnati, and then I have a Grand Slam coming. "I have to adjust my game a little bit just because the bounce of the ball is so much higher here than at Wimbledon, and there's wind, which in Wimbledon we didn't have much of. He's such a warrior out there". Whilst Federer, Nadal and Djokovic have often been able to completely dismantle opponents in their careers, they haven't always managed that. He was broken in the seventh game, but Shapovalov broke Nadal's serve a second time at 4-5 to secure the second set. "I remember when he was injured a year ago, and here he is a few matches away from clinching world No 1".

"He has a great potential". He played with the right determination in the important moments.

The win Thursday makes the teenager from Richmond Hill, Ont., the youngest Masters series quarter-finalist of all time, and the youngest Rogers Cup quarter-finalist since Bjorn Borg in 1974.
