The 25-year-old Canadian is back in the last four of a Grand Slam for the first time since the 2021 US Open after beating eighth seed De Minaur 4-6, 7-6 (9/7), 7-5, 7-6 (7/4).

“Some days you won’t feel your best but I was willing to dig really deep and do everything I can,” said Auger-Aliassime.

“It feels amazing. Four years ago, it feels like more. It was a tough couple of years but it feels even better now to be in the semi-finals.”

Auger-Aliassime, the 25th seed, on Friday plays the winner of the all-Italian quarter-final between reigning champion Jannik Sinner and 10th seed Lorenzo Musetti.

“The biggest challenges are yet to come, but that’s what I live for, that’s what I train for,” he said.

Australia’s De Minaur, 26, has now lost all six of his Grand Slam quarter-finals.

Auger-Aliassime earned his second win over a top-10 player at this tournament, having knocked out third seed Alexander Zverev in the last 32.
