Canadian Open: Jaume Munar vs Rinky Hijikata

Platform comparison

Market context

Jaume Munar’s meeting with Rinky Hijikata at the Canadian Open is priced as a clear Munar lean, with the market implying roughly a 90% chance of a Munar advance. That is far above the available betting and model estimates, which cluster much closer to a modest Munar edge: BetVictor listed Munar around -143 against Hijikata at +105, while other previews put Munar in the mid-50s to high-50s on win probability rather than anything near a near-lock.[2][4][6]

Historically, that kind of gap usually reflects event structure rather than a wholesale disagreement about who is better. In ATP first-round or early-round matches, market pricing can move sharply once line-ups are confirmed and draw paths settle, but outright probabilities in the 90s are typically reserved for cases where one side is a major favourite, the opponent is a late replacement, or the event is vulnerable to walkover-type outcomes. Here, the more comparable baseline is a standard hard-court match with Munar favoured but not dominant, which argues against treating 90% as a pure on-court win estimate.[2][6][13]

The main catalyst to watch is whether the scheduled start at 10:00am ET on 3 August remains intact and whether either player’s status changes before first serve.[1][3] If the match is played as listed, the market should ultimately track pre-match pricing and any late injury or withdrawal reports; if it is delayed, interrupted, or not completed, the settlement rules become decisive, including the 50-50 outcome in no-contest-type scenarios. Recent preview and odds pages from multiple books still show Munar as favourite, so the current crowd price appears to be leaning on the assumption that the match goes ahead on schedule and that Munar advances without major disruption.[2][9][15]
