Background

The 2025 National Bank Open, also known as the Canadian Open, is a prestigious ATP Masters 1000 event held on outdoor hard courts in Toronto from July 27 to August 7, 2025. Notably, top players such as Jannik Sinner, Carlos Alcaraz, Jack Draper, and Novak Djokovic have withdrawn from the tournament due to various reasons, including injuries and fatigue. This has elevated Alexander Zverev and Taylor Fritz as the top seeds in their absence. (tomsguide.com)

• Alexander Zverev: As the top seed, Zverev is a strong contender. He recently achieved his 500th tour-level win after a comeback victory against Matteo Arnaldi. (as.com)

• Francisco Cerúndolo: The 15th seed, Cerúndolo, advanced by defeating compatriot Tomas Etcheverry. (reuters.com)

• Alexei Popyrin: The 20th seed and defending champion, Popyrin, recently upset 10th seed Daniil Medvedev in a three-set match. (reuters.com)

Given the withdrawals of several top players, the competition in Quarter 1 is more open, providing opportunities for these players to advance.
