Diallo vs Jacquet — a hometown giant against a first-time Masters qualifier
Preview · National Bank Open, Montréal (ATP Masters 1000) · First round · 3 August 2026
Nobody in this draw has a shorter commute than Gabriel Diallo, who grew up minutes from IGA Stadium and will walk onto a Monday programme swollen by Sunday’s rain carrying the loudest support of his career and the worst form of it. Across the net is Kyrian Jacquet, a French qualifier making his first appearance in a Masters 1000 main draw and playing with the freedom that usually comes with it. The setting says one thing; the last three months say something rather different.
The matchup
Diallo is the wildcard but also the higher-ranked man, clinging to a place just inside the top 100 after a slide from the career-high perch in the low thirties he reached last August. At 2.03m he is one of the biggest players on tour, and everything flows from the serve. The return game is the weak link, and always has been.
Jacquet is 25, from Lyon, and ranked around 120 with a best of just above 100 this season. He is a small, quick, two-handed baseliner who has built his year on the Challenger circuit — including a title in Manama in February — and he has already handled a big stage, coming through qualifying at Wimbledon and reaching the second round there before Alexander Bublik ended it. To get here he recovered from a set and a break down against Alexandr Shevchenko, winning 4-6, 6-4, 6-3.
Form & conditions
This is where the match gets awkward for the home player. Diallo’s 2026 has been derailed by injury — he retired from his French Open opener against James Duckworth — and the results have never recovered. He has lost eight of his last eleven and his season record sits deep in the red, with a losing mark on hard courts specifically. There have been flashes, notably a win over Tomás Martín Etcheverry at Eastbourne, but no run.
Jacquet arrives with the better recent rhythm and no expectations whatsoever. He has been playing and winning matches at a lower level all summer, he has already won on these courts in qualifying, and he has nothing to lose in a draw he has never previously reached.
The deciding factor
Whether Diallo’s serve travels. On a quick outdoor hard court, a man of his height with that delivery should not be broken often, and against an opponent the best part of 30cm shorter with limited experience of this kind of weaponry, cheap holds are the obvious platform. The counterweight is Jacquet’s willingness to extend rallies: if Diallo’s first-serve percentage dips and the crowd’s expectation starts to press, the Canadian’s shakier groundstrokes and modest return numbers give the Frenchman a route in.
The call
The lean is to Diallo, with low confidence. The serve, the surface and the support are all in the right place, and Jacquet has never won a match at this level, but a player who has lost eight of eleven is not a safe pick against anyone. Expect it to go the distance more often than not. The winner is rewarded with 19th seed Luciano Darderi.
