Shapovalov was born in Tel Aviv, Israel, but only lived there for nine months, when his parents-Viktor and Tessa-moved the family to Canada. And as a teenager Nadal also beat a top-ranked player, stunning Roger Federer in the third round of the Miami Open in 2004.
7-6 (4), 6-3 in almost two-and-a-half hours.
Lastly, Shapovalov is the youngest player since 11-time Grand Slam champion Bjorn Borg to reach the quarter-finals of the Rogers Cup. I'm sure that he will be confident after saving a big match against (Rogerio) Dutra Silva and today winning against one of the best players of the world.
Federer was soon in control in the second set, scoring an early break and holding twice to move 3-0 up before a further break made it 4-0.
Among Shapovalov's supporters this week has been hockey great Wayne Gretzky and Canadian Olympic swimmer Penny Oleksiak.
Federer, who turned 36 this week, responded by hitting a ball into the stands, earning a reprimand but no official ball abuse call from the umpire.
Shapovalov said he didn't think he had a chance to win at all before the match.
But Federer, a three-time winner of the tournament, recovered to seal a last-eight clash against Roberto Bautista Agut.
2016 Wimbledon Juniors champion #Denis Shapovalov reveals his dream was to compete against the biggest stars of the game. And I am not happy to be part of this story.
The canary-colored top Nadal wore was already saturated with sweat when he slid an ace down the middle holding for 3-2. A double fault followed by a forehand error gave Nadal triple break point.
Nadal described it as the worst loss of the season for him for a number of reasons. "I'm trying to have the right preparation now and that's it", Nadal told the ATP's website.
The Briton withdrew from the Rogers Cup because of an ongoing hip issue which marred his recent Wimbledon campaign. If the Swiss ace wins the Rogers Cup and goes on to win the Cincinnati Open, he will become the new world number one ahead of the US Open. Instead of giving into pressure, the 18-year-old fought all the pressure points off.
"At the same time because of the opportunity I had here to come back to the No. 1".
The younger lefty confronted a love-30 hole with a shot-making tear.
"He's my idol", Shapovalov said of Del Potro. But Shapovalov trusted his game (including his sizzling one-handed backhand), even on those occasions when he found himself dangling precariously on the brink of the abyss.
Upon winning the match, the 18-year-old fell to the court with the Uniprix Stadium fans cheered deafeningly in the night.
A pulsating 10-deuce game spanned nearly 15 minutes.
Shapovalov kept his cool in key moments as he outplayed the veteran Del Potro, a former top-5 player who has dropped to 31st in ATP rankings.
