MONTREAL — Roger Federer overcame a weak first set to post a 4-6, 6-4, 6-2 victory over Spaniard David Ferrer in the third round Thursday at the men’s Rogers Cup.
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.
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.
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.
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.
Schwartzman saved four match points to upset third-seeded Dominic Thiem in the second round. The win over Donaldson put him in a quarterfinal for the sixth time this year. Schwartzman’s only ATP win was on clay in Istanbul last year.
Donaldson, 20, was seeking a first career quarterfinal in a Masters Series tournament, where he is 0-13 in round of 16 matches.
Later Thursday, Canadian Denis Shapovalov faced top seed Rafael Nadal.
