Zverev Survives Sonego in Five Sets at US Open: A Win That Exposes the No. 4 Seed's Vulnerabilities

New York, late August 2026 — When the scoreboard at Arthur Ashe Stadium flashed 6-4, 3-6, 6-7(7-9), 7-5, 6-4, many fans breathed a sigh of relief. Alexander Zverev, the No. 4 seed, had just escaped a tight battle against Lorenzo Sonego, the world No. 58, to secure his spot in the third round of the US Open. But this victory is not simply a great match — it is a clear warning signal about the German's form and consistency ahead of bigger challenges. People watch the match; I watch the match's breath. From the very first set, Zverev showed the dominance expected of his caliber, winning 6-4 convincingly. But the rhythm shifted in the second set when Sonego, with his powerful forehand and fearless attacking style, consistently pressured Zverev's serve. The third set witnessed a tense tiebreak, where Zverev lost 7-9 against his opponent's patience. This was not a complete shock — Sonego once beat Novak Djokovic at Vienna in 2026 and has always been a threat to top players when in form. But for a title contender, losing two sets to a player outside the top 50 in a Grand Slam match is a worrying sign. What helped Zverev turn the tide? The answer lies in his serve — his most lethal weapon. At 1.98m, Zverev has an angle advantage few players possess. In sets 4 and 5, as Sonego began to show signs of fatigue, Zverev maximized his first-serve points to hold games comfortably. He won 7-5 and 6-4 in the final two sets, demonstrating his ability to capitalize on his opponent's tiredness — a crucial quality in a tournament as long as the US Open. However, watching the entire match, I noticed Zverev still struggled with short balls and deep returns from Sonego — a weakness that bigger opponents will exploit ruthlessly. The truth is, this victory cannot hide the fact that Zverev needed five sets against a world No. 58. In the context of the 2026 US Open, where both Novak Djokovic (third round) and Carlos Alcaraz (second round) exited early, Zverev's opportunity to go deep was enormous. But this match against Sonego exposed a lack of consistency in his game — a problem that has followed Zverev throughout his career. He has reached the US Open final in 2026 and the French Open final in 2026 but has never won a Grand Slam. The label of "nearly man" is not what fans want to hear, but the data supports it: Zverev's win rate in crucial late-round matches is below his ranking tier's expectation. Many argue that surviving a five-set match is proof of Zverev's resilience. But looking closer, I see the opposite. A true title contender should dispatch a player like Sonego in three or four sets. Needing five — and losing a tiebreak — suggests suboptimal form. This becomes clearer when reviewing Zverev's results before the US Open: he lost early at Cincinnati (second round, to Alejandro Tabilo), indicating his hard-court form was not at its peak. The match against Sonego was not a great victory; it was a warning about the difficulties ahead. Another notable point is how Zverev handled pressure in the tiebreak. He lost 7-9 in set 3 — a scoreline reflecting indecision in crucial points. Zverev's career tiebreak record is below the average of top-5 players. This is not accidental: it stems from his tendency to play too passively in decisive moments rather than attacking proactively. Meanwhile, Sonego — despite losing — showed a commendable fighting spirit, unflinching against his senior. If Zverev does not fix this weakness, he will continue to struggle in later rounds. The Moscow door opened, and I stepped into the fans' world. After the match, I spoke with a group of German supporters in the stands. They admitted they were breathless with worry watching Zverev lose set 3. "We know Sascha can play better than this," one said. "But at least he got through." That anxiety reflects the general sentiment: fans believe in Zverev's talent but are uncertain about his ability to overcome the hardest moments. This becomes even more critical as Zverev enters the third round with pressure to go deeper. When the court is empty, I hear the match's voice more clearly. Leaving Arthur Ashe Stadium, I couldn't help thinking about the numbers. Zverev won, but he needed five sets against a player outside the top 50. He won two decisive breaks in sets 4 and 5 but lost one break in set 2 and one in set 3. The class gap was not large enough to produce an easy win. And that, for a No. 4 seed at a Grand Slam, is a problem that needs immediate resolution. Looking ahead, I believe Zverev must improve two things to go deep at the 2026 US Open. First, he needs to be more proactive in crucial points, especially tiebreaks. Second, he must improve his handling of deep returns and short balls — situations Sonego exploited successfully in the first two sets. Otherwise, Zverev will continue to struggle against aggressive players like Taylor Fritz — whom he might face in the next round and who, in fact, eliminated him in the quarterfinals. A tactic never dies; it just waits for someone who understands it. The victory over Sonego is a valuable lesson for Zverev — not about winning, but about facing pressure. He showed remarkable recovery by coming back from 1-2 to 3-2, a positive sign of mental strength. But in a tournament as demanding as the US Open, where every opponent can cause an upset, Zverev needs to rediscover consistency in his game. Can he do it? The answer will come in the third round, where he faces a new challenge. I will watch, not to judge, but to understand — because I am old, but the pulse of the ball never ages.
