Hurkacz Is Effectively Withdrawn — Van de Zandschulp Advances
A 99% price on Van de Zandschulp's progression, on nearly $8 million in volume, signals something beyond an ordinary upset.

Hubert Hurkacz is, to all practical purposes, out of the National Bank Open. Botic Van de Zandschulp's round-of-32 match against the Polish veteran has resolved in the Dutchman's favor with a certainty that leaves no room for ordinary sporting suspense — the deepest money in the market, approaching $8 million traded, has priced Van de Zandschulp's progression at 99%. At those odds, this is not a prediction; it is a confirmation.
The scale and speed of the repricing — a 67-point swing in a single day, on volume that dwarfs anything else moving in this tournament — almost certainly reflects a known physical fact rather than a shift in tactical assessment. When a match market moves that violently, that fast, on that much money, the most plausible explanation is that informed participants know something definitive: a retirement, a withdrawal, an injury that ended play. The money is not handicapping tennis; it is pricing in a result already effectively settled.
There is a cross-venue wrinkle worth noting. One smaller venue had priced Van de Zandschulp's win at just 26% — a figure that, against the deeper market's 97-to-99% consensus on roughly 160 times the volume, is best understood as a stale or mis-keyed line rather than a genuine disagreement about the outcome. The deeper market has spoken too loudly and too specifically to leave the discrepancy open to interpretation.
The broader Montreal draw, meanwhile, tells a more genuinely uncertain story. Naomi Osaka looks likely to dispatch Elise Mertens — the handicap lines suggest a straight-sets win is the expected path. Jakub Mensik and João Fonseca, two of the circuit's most watched young players, face tighter propositions: Mensik at roughly two-in-three against Terence Atmane, Fonseca in a near-coin-flip against Casper Ruud, a match the money finds too close to call with confidence. The tournament's overall favorite picture remains genuinely open, with Ben Shelton attracting fresh attention at 22% to win the ATP title — meaningful movement, but still a lean in a crowded field, not a coronation.
For Van de Zandschulp, the path forward is what matters now. He advances into a draw that, absent Hurkacz, has lost one of its more dangerous hardcourt presences. Whether the Dutchman can capitalize — and whether Osaka's projected run, Gauff's steady 78% handle, or Shelton's late surge shapes the tournament's final act — is where the real betting story now lives. Hurkacz's exit, whatever its cause, has reshuffled the bracket in ways the money is only beginning to price.
The signal to watch: if Shelton's tournament odds continue climbing while Fonseca holds serve against Ruud, the market may be sketching a bracket that opens up dramatically on the men's side. A Fonseca win over Ruud — still a genuine toss-up — would be the data point that breaks or confirms Montreal's emerging shape.
