Alex de Minaur has stunned the tennis world with a remarkable point on his way to the quarter-finals of the Canadian Open.

In a battle between two of the best movers on the men’s circuit, ninth-seeded de Minaur fought off seventh-seeded American Frances Tiafoe 6-2 4-6 6-4 in their round-of-16 clash in Toronto on Sunday (local time).

The Australian got off to a sizzling start, racing through the first set 6-2 before Tiafoe regrouped in the second to force the match into a decider.

But it was at 4-4 and deuce in the deciding set when the match was turned on its head with one of the points of the year.

Tiafoe, who was serving, appeared to have done enough to win the point several times, only for de Minaur to extend the point with some unbelievable shots.

The American crunched a short forehand wide into the corner, but was left shocked as de Minaur anticipated it and miraculously kept the ball back in play.

Tiafoe then played a clever drop shot, but de Minuar then showed off his blistering pace to chase it down and force his opponent into an error.

The Aussie then landed the crucial break before serving out the match.

But it was that pivotal point that had everyone talking.

“Are you kidding me? The Demon at his vert best,” the commentator said.

“There’s just some turbo boosters with that movement, that was just unbelievable.”

De Minaur’s renowned return game held him in good stead as he converted five of the 10 break points he generated during the match, compared with the American’s three of seven chances.

However, the Australian will be looking for an improvement on his service game for his quarter-final, after landing just 42 per cent of his first deliveries.

Tiafoe hit more aces than de Minaur (10 to six) and more winners (29 to 23), but the American also gave up more free points with unforced 49 errors, compared with 35 from his opponent.

“It was never going to be easy, and Frances has the ability to turn the switch on whenever he wants, so it is always very tricky to put him away,’‘ de Minaur said after the match.

“I think I battled him, myself and the conditions, and I am happy to sneak away with the win today.’‘

De Minaur has found a rich vein of form in the countdown to the year’s final major, the US Open on the hard courts at Flushing Meadows in New York, which starts on August 24.

The Australian is already a two-time US Open quarter-finalist (2020 and 2024) and has his sights set on making his first grand slam semi-final, having reached the quarters of all four majors.

His timing could not be better, de Minaur coming to Toronto after clinching the Washington Open singles championship last week, his 10th ATP Tour title.

The Washington event was also played on hard courts, making the Aussie one of the most in-form players on the surface.

His win over Tiafoe stretched de Minaur’s winning streak to eight matches.

De Minaur has previously reached the Canadian Open final, losing the 2023 decider against Italy’s Jannik Sinner, who has since risen to the top of the world rankings.

De Minaur is not the only Australian left in the men’s singles in Toronto, with 18th seed and defending champion Alexei Popyrin to take on top-seeded German Alexander Zverev.

Both of the quarter-finals will be played on Monday (Tuesday AEST).
