Montreal's Masters Miscalculation The withdrawals of Jannik Sinner and Novak Djokovic from the National Bank Open in Montreal have left a gaping hole in the men's tennis calendar, raising questions about the ATP Masters 1000 format's viability.
The two week events introduced last year have been met with criticism from players and fans alike, who argue that they're more exhausting than beneficial.
Critics point out that the new format extends tournaments like Canada and Cincinnati to 12 day events, which seems to be having the opposite effect of giving top players more time to prepare for the US Open.
