Canadian teenager Denis Shapovalov upset top-seeded Rafael Nadal 3-6, 6-4, 7-6 (4) in the third round of the Rogers Cup on Thursday night.
The 18-year-old Shapovalov, from Richmond Hill, Ontario, advanced to a quarterfinal meeting Friday night with France’s Adrian Mannarino, who defeated Hyeon Chung of South Korea 6-3, 6-3.
Nadal could have overhauled Andy Murray as the world No.1 if he reached the semi-finals of the tournament, but he has been made to wait.
Shapovalov has taken major strides this week to reach his goal of cracking the world’s top 100 with wins over Rogerio Dutra Silva and 2009 U.S. Open champion Juan Martin Del Potro. He also halted Nadal’s bid to regain the No. 1 ranking, which the Spaniard could have achieved by reaching the semifinals.
Shapovalov battled back after Nadal cruised through the first set, then erased a 3-0 deficit in the tiebreaker for the biggest victory of his career.
Nadal was clearly unhappy with the defeat, which has thrown his US Open preparations off track.
“It’s my worst loss of the year because it’s a loss to the opponent with the lowest ranking and because I had chance to be No. 1,” he told reporters.
Roger Federer marches into Qurter-finals of Montreal
Roger Federer overcame a weak first set to post a 4-6, 6-4, 6-2 victory over Spaniard David Ferrer in an earlier third-round match.
In Friday’s quarterfinals, the second-seeded Federer will face 12th-seeded Roberto Bautista Agut of Spain, who outlasted Frenchman Gael Monfils 4-6, 7-6 (5), 7-6 (2) on center court at Uniprix Stadium.
Federer, who breezed past Canadian Peter Polansky in the second round on Wednesday, struggled in the opening set, spraying balls long, wide or into the net, but gradually rediscovered at least some of the form that has seen the 36-year-old Swiss earn two grand slam wins this year.
Federer is 17-0 in his career against the 35-year-old Ferrer, who was ranked third in the world in 2013 but is now at No.33.
