The Canadian Open has already kicked off in Toronto: a Masters 1,000 tournament as part of the hard court season, currently named National Bank Open, that will last until August 7. Australian player from Russian parents Alexei Popyrin will defend the title he won against Andrey Rublev last year.
With the first qualifying round already under way, the 32 seeded players got a first-round bye and will make their debuts on Tuesday, July 29 (at dawn in European time). With the absences of Jannik Sinner and Carlos Alcaraz, World No. 3 Alexander Zverev will be the top seeded player, hoping to add another title this year after the Munich Open, in the season that saw him losing the Australian Open final to Sinner. It was in 2017 where he won his only Canadian Open, the first of seven Masters 1,000 titles.
