Carlos Alcaraz recovers after dropping the first set to reach the second round at the US Open

A cross-court forehand return, the ball landing exactly in the corner of the opponent's side. Alcaraz raised his arm to the sky, letting out a long shout. That was the moment I knew this match would not follow the script most fans in Arthur Ashe Stadium were expecting. Based on my experience following matches over many years, the moment a young player begins finding the right angles after a frustrating first set is often the line between an easy win and a prolonged battle. But with Alcaraz, that line is always thinner than people think. His opponent in the first round at the 2026 US Open was not a name to be easily dismissed. He stepped onto the court with the confidence of a player with nothing to lose, serving accurately and moving fluidly on the hard court. The first set unfolded with extended rallies, where Alcaraz was constantly pushed out of his controlling position. His opponent's first-serve percentage in the opening set reached an unusually high level, preventing Alcaraz from attacking from the start of the point. In the stands, a portion of the crowd began to whisper. I sat in the press area, noting down a number: in the first set, Alcaraz won only 38% of his return points. That number is not a disaster, but it is not the number of a player controlling the match. The truth lies deep beneath the numbers, where headlines never reach. And the truth here is that Alcaraz was not playing badly in the first set. He was just playing in a way his opponent had studied carefully. When I reviewed data from Alcaraz's recent matches on hard courts, a pattern emerged: in his last three tournaments on this surface, he tends to start significantly slower than on clay. This is not a weakness, but a characteristic of how he approaches matches — he needs time to read the opponent's serve rhythm before adjusting his return position. After losing the first set 6-4, Alcaraz entered the second set with a subtle change. He stood about a meter further back from the baseline when returning serve. This adjustment seems small, but it completely changes how he receives deep serves. Instead of trying to hit the return immediately at the bounce, he creates more time to place the ball deep, shifting the match from a serving battle to a rally battle. His return point win percentage in the second set rose to 52%. That is a structural change, not a lucky burst. But I do not want to paint a simple picture of a great player self-correcting. Because what made this match more interesting than the headline suggests is how Alcaraz's opponent reacted to that adjustment. Instead of continuing to hit deep and wait for errors, he began changing tempo — unexpected drop shots, serve-and-volley to shorten points. In the third set, Alcaraz faced a series of situations where he was not allowed to lose focus. I recalled a match at Wimbledon a few months earlier, where he lost to a player with a similar style, and the question in my mind at that moment was whether he would repeat that script. Fans look with their eyes, I look with probability distributions. And the probability distribution at that moment favored Alcaraz, but not as much as people thought. His first-serve win percentage in the third set dropped slightly compared to the second, but his return win percentage remained above 50%. That means he was winning the match from the return side — a sign that the tactical adjustment was working. But it also showed he had not yet found full comfort in his own service games. The turning point of the match came in the seventh game of the third set. Alcaraz was leading 4-3 with his opponent serving. A series of extended rallies lasted up to 20 shots, and finally Alcaraz won the point with an impossible cross-court backhand. That moment not only gave him a break point, it sent a message to the entire stadium: this match was ending the way the Spaniard wanted. He converted the break, held serve, and closed out the third set 6-4. The fourth set saw a completely different Alcaraz. Confidence returned to every shot, and his opponent began showing signs of fatigue — not physical, but mental from constantly facing balls placed in the most uncomfortable positions. Alcaraz closed the match 4-6, 6-4, 6-4, 6-2, and I recorded one final number: he won 61% of return points in the final two sets. That is a number belonging to a player at an entirely different level. But I do not want to end the article here, because there is something the data cannot capture: how Alcaraz handled the pressure in the first set. I have watched many talented young players collapse after losing a difficult first set. They start hitting harder, taking more risks, and often making errors. Alcaraz did not do that. He accepted the reality that his opponent was playing better, and he chose to patiently wait for the right moment to change the course of the match. This is a quality that no statistic can measure, but it may be the most important reason he has won so many big titles at such a young age. I recall a conversation with another data analyst before the tournament. He told me that Alcaraz losing the first set in a match is a positive signal, because his win rate after losing the first set in his career is very high. I do not entirely agree with that interpretation, because it ignores the context of each specific match. But I understand what he meant: Alcaraz is a player with extraordinary adaptability, and facing difficulty early often triggers an adjustment process that few players possess. A counterintuitive perspective I want to offer here is: Alcaraz losing the first set may actually be a good thing for his US Open campaign. Not because it prevents complacency, but because it provides his coaching team with valuable data on how opponents approach matches against him. In the first round, when opponents usually have little information about each other, a difficult set can be a more valuable test than a quick win. Of course, this is an interpretation that can be challenged, and I am not highly certain about it. But one thing I am more certain about: if Alcaraz continues to maintain his return point win percentage above 50% as he did in the final two sets of this match, he will be a strong contender for the title. The hard court conditions at Flushing Meadows this year seem faster than previous years, which favors players with good serves. But Alcaraz has proven he can overcome early disadvantages through patience and match reading ability. His biggest question in this tournament is not fitness or technique, but whether he can maintain focus in matches where he does not get a smooth start. As I left Arthur Ashe Stadium that night, I saw Alcaraz signing autographs for a group of children in the hallway. The closest boy asked him why he was not worried when he lost the first set. Alcaraz smiled and answered in Spanish that I could not fully hear. But I think I know the answer: because he believes in his process, and that process has been built through thousands of hours of practice and hundreds of matches. Data can record what happened on the court, but it cannot record that belief. And perhaps, that belief is the most important factor determining how far a player can go at a major tournament. Alcaraz's next match will be another test. His second-round opponent will have an extra day of rest, and that could make a difference in long games. But if there is one thing this match has taught us, it is that underestimating Alcaraz's adaptability is a mistake many opponents have paid for. I will be closely monitoring his return point win percentage in that match, because it is the most reliable indicator of whether he is on the right track. The court does not lie, and neither does the data. But between the court and the data, there is a space that only those who truly understand this game can see — and Alcaraz lives in that space.
