Zverev benefits from Cerundolo's withdrawal in Toronto, Popyrin still in contention for a Canadian double
After the qualifications of Karen Khachanov and Alex Michelsen earlier in the day, two more players advanced to the quarterfinals of the Toronto Masters 1000 overnight from Saturday to Sunday.
First, Alexander Zverev held his ground. The German, seeded No. 1 in Canada due to the absence of Sinner and Alcaraz, took advantage of Francisco Cerundolo's withdrawal due to an abdominal injury early in the second set (6-4, 1-0 ret.).
Having lost to the Argentine in their three previous meetings, Zverev finally overcame Cerundolo for the first time in four encounters, though it’s likely not the way he would have preferred to secure his spot.
For a place in the semifinals, he will face defending champion Alexei Popyrin, who remains in contention to achieve a double—a feat not seen in Canada since Rafael Nadal in 2018 and 2019.
The Australian, who was on a three-match losing streak before returning to Canada, has proven he can rise to the occasion in this tournament.
After victories against Nicolas Arseneault and Daniil Medvedev, the world No. 26 rallied past Holger Rune (4-6, 6-2, 6-3) and reached the quarterfinals of a Masters 1000 for the fourth time in his career (Cincinnati 2023, Montreal 2024, Monte-Carlo 2025, and Toronto 2025).
