Luca van Assche vs Denis Shapovalov prediction time, and T Money is not putting a stake on this one. Shapovalov is the market favorite at -161 for their second round meeting at the US Open on September 2, with first ball at 2:30 PM ET. He is also the side our own read leans toward on style, but the tier here is PASS. That means we are not backing this match officially. Here is why the number never got there.
The short version: Shapovalov looks like the stronger stylistic matchup for a five set hard court fight, but his serve has looked fragile in exactly the way that costs matches, and Van Assche is coming in far sharper than his ranking suggests. Two real signals pulling in different directions is what a pass looks like.
Why the lean is Shapovalov
Strip away reputation and this comes down to serve and return archetypes on hard courts over the last twelve months. Shapovalov has held serve on roughly 78 percent of his service games and won about 26 percent of his return games across 317 hard court service games against solid opposition. Line that up against players who serve like Van Assche does (a low serve index, more of a grinder profile than a first strike weapon) and Shapovalov's hard court record against that exact archetype is 9 and 3, winning a third of his return games in those matchups. That is the structural case for the favorite: a lefty first striker against a low serve, high effort counterpuncher is a matchup type Shapovalov has already solved repeatedly this year.
His US Open opener backs it up on paper. He beat Miomir Kecmanovic in four sets and did it with 64 winners and 85 percent of points won behind his first serve when it landed. That is a huge number. When Shapovalov's serve is working, it is one of the more dangerous shots in this draw.
The case against
Here is the problem: that same opener showed exactly the flaw our risk notes flagged. Shapovalov made only 51 percent of his first serves and put up somewhere between 11 and 13 double faults in that match. A player generating elite numbers off a serve that is only landing half the time is living dangerously, and Van Assche returns second serves as well as almost anyone in this bracket, winning around 54 percent of second serve return points on tour. If Shapovalov's first serve percentage does not climb, Van Assche gets the exact number of second serve looks his game is built to punish.
Van Assche also arrives in far better form than a quick ranking check would suggest. He won a hard court Challenger title in Quebec City nine days before this match, beating a 6 seed and a 4 seed along the way, then followed it with a four set win over Cameron Norrie in the first round here, an 84 percent hold rate and 8 of 12 break points converted. That is a career high level of play on the exact surface this match is being played on, not a cross surface data point we are borrowing to make a case. His current ranking of 40 is a career best, and it undersells where his game is right now.
There is also the fatigue and history angle. Van Assche has played six matches in thirteen days against an opponent who has played once in fourteen, so Shapovalov should have the fresher legs. But Shapovalov's 2026 has included an ankle retirement in Montreal in early August along with a season of rib, shoulder and knee trouble, and if this stretches to a fifth set his risk notes flag that history as a real concern late in a long match.
The number that matters
Van Assche's lone previous meeting with Shapovalov came at the 2024 French Open, on clay, best of five, and Shapovalov won in straight sets. That result is more than two years old and on a different surface, so it carries almost no weight here. It is mentioned only because it exists, not because it tells us anything about a hard court match in 2026.
What actually decides this for T Money is that two real, current signals point opposite directions. The style matchup and the return numbers favor Shapovalov. The serve reliability, the current form gap, and the injury history favor caution on him, or even a case for Van Assche. At -161, Shapovalov is not an outrageous price for a talented lefty first striker, but we are not going to dress up a split read as a confident bet just because the market leans one way.
The verdict
PASS. This is an official card pass, not a soft lean and not a play we are quietly making anyway. Shapovalov's stylistic edge and Van Assche's hidden form and return numbers cancel each other out too closely for us to put a number behind either side at this price. No stake, no side named as a bet here.
