The Canadian Open's round of 64 gets a star-studded Wednesday at IGA Stadium, with top seed Alexander Zverev and home favorite Felix Auger-Aliassime anchoring a packed Center Court card that opens at 11:00 a.m. local time.

Day-session intrigue starts with Stefanos Tsitsipas, through qualifying, against rising Brazilian Joao Fonseca, followed by Jenson Brooksby versus fifth seed Ben Shelton. Zverev then faces Tallon Griekspoor in the afternoon slot organizers have flagged as one of the day's must-see matches.

The night session belongs to Montreal. Auger-Aliassime, the second seed, opens against French qualifier Titouan Droguet not before 7:00 p.m., with Learner Tien against wild card Gael Monfils to close Center Court. Monfils has drawn farewell tributes around the grounds, adding emotion to an already electric home-crowd night.

Rogers Court is nearly as stacked. Eleventh seed Lorenzo Musetti opens against qualifier Nicolas Mejia, Casper Ruud meets Juan Manuel Cerundolo, and Taylor Fritz takes on Thiago Tirante before Daniil Medvedev's evening opener against Botic van de Zandschulp not before 6:00 p.m. Tommy Paul closes that showcourt against Valentin Royer.

Elsewhere, Hubert Hurkacz continues his protected-ranking return against Alejandro Tabilo, Cameron Norrie faces Ignacio Buse after his opening win, and Arthur Fils, Ugo Humbert, and Francisco Cerundolo all feature on the outside courts. With Sinner, Djokovic, and Alcaraz absent, Wednesday's slate is the clearest look yet at who is ready to own this Masters 1000.
