MONTREAL, Canada (AFP) — Alex de Minaur blew through the opening set but needed some good luck in the second to emerge with a 6-2, 7-6 (8/6) opening win over James Duckworth on Tuesday at the ATP Montreal Masters.

De Minaur, seeded third, hasn’t lost to a fellow Aussie in four years, but he was made to work hard by his 86th-ranked compatriot to keep that streak alive.

The second-round match turned in an instant in the second-set tiebreaker when a return which rolled off the top of the net handed De Minaur a match point after he saved six set points for his opponent.

“A little bit of luck went my way in the tiebreaker,” De Minaur said.

“He was hitting me off the court in the second set, but I got lucky and managed to sneak away with the tiebreaker.”

“Ultimately it was a lot of fighting and competing,” added De Minaur, the 2023 runner-up in Canada who married British WTA player Katie Boulter last month.

De Minaur said he hasn’t given much thought to his solid recent record against fellow Aussies.

“We’re doing our best to make Australia proud,” he said.

“We have strength in numbers.”

In other second-round action China’s Shang Juncheng — only just returned from months away because of injury — scored the first notable upset of the week with 7-5, 4-6, 7-6 (7/5) defeat of 10th seed Andrey Rublev.

Shang saved five match points, on his way to the third round, breaking Rublev as he served for the match at 5-3 in the third and hanging on to win a seven-deuce service game.

Former world No. 3 Stefanos Tsitsipas regained some of the touch lost during a recent rankings slump, with the high-profile qualifier dispatching Martin Damm 6-4, 6-4 in a first-round match delayed by rain.

The 98-minute victory sends Tsitsipas into a match with Brazilian Joao Fonseca.

The 53rd-ranked Tsitsipas, winner last month in Gstaad, said that his latest coaching split from his father, Apostolos, is paying off.

“It’s a chapter that should have started a long time ago,” Tsitsipas said.

“I guess I was too patient with my time and too nice with handling certain things, to take so much time to proceed with the change. But it’s how life works.”

“Certain things come at a certain time, I’m very Buddhist in that sort of philosophy.”

The Greek claimed the opening set against Damm and came back from a break down in the second to earn a 5-2 lead and the chance to serve it out.

Damm managed to break back before Tsitsipas clinched the victory two games later.

Hubert Hurkacz, a 2022 finalist in Montreal who is coming back from a knee injury suffered at Wimbledon, beat Marcos Giron 7-5, 4-6, 6-2.

Great Britain’s Jakob Fearnley, who reached the final of a hardcourt Challenger last month, advanced past French veteran Adrian Mannarino 7-6 (7/3), 6-4, overcoming more than 30 unforced errors to book a meeting with 13th seeded Czech Jakub Mensik.

Fellow British Jack Draper shed bitter tears as his latest injury comeback collapsed in a 6-3, 2-6, 6-2 loss to France’s Terrance Atmane, who delivered an ace on match point.

Draper, who had not played a match since Eastbourne in June, was consoled at the net by his victorious opponent.

It was more disappointment for Draper after he and new coach Andy Murray traveled to last week’s Washington event only for Draper to withdraw as an existing arm injury flared up.

Canadian Denis Shapovalov, who reached the final in Los Cabos at the weekend, was disappointed to retire with an ankle injury to hand a 4-6, 6-4, 3-0 victory to Zachary Svajda.
