Nadal upset by Canadian teenager in Montreal

MONTREAL (AP) — Canadian teenager Denis Shapovalov upset topseeded 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.

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.

Roger Federer overcame a weak first set to post a 4-6, 6-4, 6-2 victory over Spaniard David Ferrer in an earlier thirdround match.

In Friday's quarterfinals, the second-seeded Federer will face 12thseeded Roberto Bautista Agut of Spain, who outlasted Frenchman Gael Monfils 4-6, 7-6 (5), 7-6 (2) on center court at Uniprix Stadium.

Unseeded Argentine Diego Schwartzman posted a strange win over American Jared Donaldson 0-6, 7-5, 7-5 to advance to a quarterfinal meeting with Robin Haase, the 52nd-ranked Dutchman who upset seventh-seeded Grigor Dimitrov of Bulgaria 7-6 (3), 4-6, 6-1.

Kevin Anderson of South Africa downed American Sam Querrey 6-4, 6-1 and will next play fourth-seeded Alexander Zverev, who ousted 16thseeded Nick Kyrgios 6-4, 6-3.

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-yearold 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.

Bautista Agut fought off a match point to force a tiebreaker, which the tired- looking Monfils opened with a double fault and never challenged again.

The unseeded Monfils played his third straight three-set match, including an upset win over fifth-seeded Kei Nishikori in the second round.
