Jesper de Jong gets the biggest match of his French Open run on May 31, 2026, when he faces Alexander Zverev in the fourth round at 15:30 CEST. De Jong has already spent nearly five hours on court in Paris, but the reward for that marathon is a meeting with the tournament’s clearest title favorite.
The Dutch player has won four of his last five matches to reach this stage, and the path has not been gentle. He beat Stan Wawrinka in four sets in the opening round, recovered from a 1-3 deficit in the first set against Cina to win in straight sets, then survived Karen Khachanov in five tight sets after almost five hours in the third round. That win over Khachanov is the reason de Jong is being searched now: it pushed him into a fourth-round match few would have expected him to reach this quickly.
Zverev has arrived with his own momentum. He has won four of his last five matches, dropped Bonzi and Machac in straight sets in the opening rounds, and outlasted Halys in four sets in the third. He was also the French Open finalist in 2024, which helps explain why he is being framed as the biggest favourite to win the title this year. For bettors, the angle is straightforward enough: covering the games handicap is being viewed as value, with -7.5 games offered at 1.67 with bet365.
The matchup still carries a question that numbers alone cannot erase. De Jong has confidence and a result that will travel well beyond the clay, but he also comes in off a five-hour battle that can leave even the freshest player flat the next day. Zverev, by contrast, has been far more efficient through the draw, and the head-to-head record cited for the pair is 0-2. That leaves de Jong trying to do something harder than pulling off another upset: recover quickly enough to make the favorite feel pressure on a day that already points strongly one way.
If de Jong is to change the shape of this French Open match, he has to do it before the fatigue shows. If he cannot, Zverev looks positioned to keep the run on schedule and justify the billing that has followed him through Paris.
