National Bank Open: Nicolas Mejia vs Martin Landaluce

Platform comparison

Market context

Nicolas Mejia’s first-round meeting with Martin Landaluce at the National Bank Open is pricing as a clear underdog for Mejia, with the crowd giving him only a 14% chance. That sits well with the broader profile: the pair have no head-to-head history, Landaluce is ranked higher, and he has already shown more at Masters level, with a 4-4 career record in Masters first-round matches[2][3][11]. Mejia, by contrast, is making his first main-draw appearance in a Masters event and is still seeking a first main-draw win on tour-level hard courts, where his record is 0-3[2].

The number is also shaped by surface and recent sample size. On hard courts this year, the two have been broadly comparable in raw win rates, but Landaluce’s larger volume against higher-level opposition and his 14-11 record against players outside the top 100 in 2026 points to a steadier baseline[1][2]. Mejia’s recent results look stronger in some match-tracking feeds, but those are form snapshots rather than evidence of a proven hard-court ceiling, and they need to be weighed against his lack of tour-level wins on the surface[4][7].

For traders, the main catalysts are straightforward: whether the match is confirmed to start on schedule, whether either player is listed with any last-minute withdrawal or fitness issue, and whether the draw is reshuffled by any earlier cancellations or rain delays. Because the market settles to 50-50 if the match is not played, or if it is delayed beyond seven days without a winner, the key risk is not just who is better, but whether the fixture is completed inside the settlement window[2].
