Carlos Alcaraz returns to the courts of the US Open in good form. Last year, he had an unpleasant 2nd round surprise when Dutchman Van De Zandschulp eliminated him by beating him 1-6, 5-7, and 4-6 in the most surprising result of the tournament. Now the Murcia native arrives at a high point, having been crowned champion at the Cincinnati Masters 1000, after Sinner withdrew from the final, claiming to feel ill and low on energy.

Since the clay season began, the year has taken a favorable turn for Alcaraz, the former world #1 Spaniard, who made the 2025 season his most successful in terms of titles, with the Asian tour still to come. His victories were in Cincinnati, London, the French Open, Rome, Monte Carlo, and Rotterdam.

Even so, Alcaraz will face a different challenge, as this is the first time he has faced the tallest player on the circuit and also the most powerful server, Reilly Opelka. Alcaraz will have to stick to his plan and be patient; if possible, make him play as much as possible and take care of his own serve.

Our Reilly Opelka vs Carlos Alcaraz Prediction

Opelka managed to hit 55 aces during his time in Cincinnati, but he also had periods of inaccuracy with his serve. Unfortunately for the American, these inaccuracies occurred in particular games. Opelka saved a huge number of break points until Comeseña broke his serve four times in the elimination match.

Meanwhile, Alcaraz combined his usual intensity with the ease he typically displays in tournaments he ends up winning, as was the case in Cincinnati. In the betting markets, Alcaraz is the second favorite to win this US Open.

Our prediction for Alcaraz vs. Opelka is: Under 36.5 games.
