Top-seeded Alexander Zverev achieved a significant career milestone at the National Bank Open in Toronto, securing his 500th ATP Tour match victory by overcoming Matteo Arnaldi of Italy in a hard-fought third-round encounter.

The German prevailed with a score of 6-7 (5), 6-3, 6-2, demonstrating resilience after dropping the first set in a tie-break. Zverev, who previously clinched the Toronto title in 2017, showed remarkable composure to regain control of the match, extending his impressive run in the National Bank Open.

Reflecting on his performance, Zverev noted, “I think I started playing better from the baseline. The longer the match went on, I started to find my rhythm a bit.” He also commented on an unusual initial struggle with his backhand, which he later rectified to elevate his game and secure this historic ATP Tour win.

Zverev, currently ranked third globally, assumed the top seed position for this prestigious Toronto Tennis event following the withdrawals of top-ranked Jannik Sinner and second-ranked Carlos Alcaraz. High-profile players like Jack Draper and Novak Djokovic were also absent, highlighting the competitive field despite some notable absences in this Men’s Singles tournament.

In another compelling Tennis Results from the day, American qualifier Alex Michelsen delivered a major upset, defeating third-seeded Lorenzo Musetti of Italy with a score of 3-6, 7-6 (4), 6-4. Michelsen’s impressive run will see him face fellow American Learner Tien in the next round, who advanced after beating Reilly Opelka.

Further deepening the tournament’s narrative, fifth-seeded Holger Rune of Denmark secured his progression by beating Alexandre Muller of France 6-2, 6-4.
