MONTREAL — Pablo Carreno Busta of Spain won the National Bank Open, beating eighth-seeded Hubert Hurkacz of Poland 3-6, 6-3, 6-3.
The first unseeded winner in the event since Argentina’s Guillermo Canas in 2002, Busta won his seventh ATP Tour title and first Masters 1000 victory.
“It’s an amazing feeling,” Busta said. “I worked very, very hard (throughout) my career to finally be here.”
The 23rd-ranked Carreno Busta improved to 7-5 in final appearances.
“It’s not the first one, but it’s for sure the most important,” Carreno Busta said. “It’s a Masters 1000. It’s something great to win these kind of titles.”
Hurkacz fell to 5-1 in finals.
“It’s the little things that make a big difference,” Hurkacz said. “If you don’t make your first serves and, with Pablo making some good returns, then you’re under a lot of pressure.”
Unseeded Reilly Opelka reached the final last year in Toronto, then lost to Daniil Medvedev.
DALLAS – Marcos Giron advanced to the second round of the Dallas Open with a 6-4, 6-7 (1), 6-1 victory over Alex Rybakov on Tuesday.
The seventh-seeded Giron, who reached the semifinals of the inaugural event a year ago, responded quickly after failing to close out the second set, winning the first five games of the deciding set.
Rybakov broke his fellow American when Giron was serving for the match in the second set. Then Rybakov won the first six points of the second-set tiebreaker.
“I’m really happy with how I was able to reset in the third and just get back to the game plan from the beginning and elevate,” Giron said. “He played well and served well and kind of hung in there.”
Eighth-seeded Adrian Mannarino of France won the final five points of a first-set tiebreaker and the last four games of the second to beat American Steve Johnson 7-6 (6), 6-2.
J.J. Wolf, the No. 6 seed, had little trouble in a 6-3, 6-3 victory over fellow American Brandon Holt.
John Isner, the fifth seed and unofficial tournament host in his hometown event, played later Tuesday. Like Giron, Isner lost in the semifinals last year.
DALLAS – Wild-card entry Jack Sock opened with a 7-6 (2), 4-6, 6-4 victory over Ilya Ivashka at the Dallas Open, setting up a second-round meeting with top-seeded fellow American Taylor Fritz.
Sock broke Ivashka’s serve in the final game to win the match. Ivashka fell behind 2-0 to start the final set but broke Sock to get back on serve.
Down a break early in the second set, Ivashka rallied to force the deciding set after Sock cruised in the first-set tiebreaker.
The eighth-ranked Fritz is back for the second Dallas Open after losing in the semifinals as the top seed in the inaugural edition of the indoor hard-court event last year. Defending champion Reilly Opelka isn’t in the field.
