NEW YORK, UNITED STATES, September 11, 2026: Alexander Zverev needed three sets to reach the US Open final, but the scoreline hides how little separated him from Karen Khachanov at Arthur Ashe Stadium.
Zverev defeated Khachanov 6-3, 7-6(7), 7-6(6) in the first men’s semifinal, reaching his second US Open final and extending a remarkable 2026 Grand Slam season in which he has now made three consecutive major finals.
The German did not dominate every category.
Khachanov put 74% of his first serves into play compared with Zverev’s 68%. He won 78% of those first-serve points, three percentage points better than Zverev, and collected more receiving points, 33 to 29.
The entire match nevertheless tilted toward Zverev because of what happened when the sets stopped being ordinary.
He won both tiebreaks.
He converted two of his three break-point opportunities.
And when Khachanov repeatedly brought the semifinal to the edge of a fourth set, Zverev kept finding the serve, return or first strike that prevented the match from turning.
That ability to control the biggest moments has become increasingly important in Zverev’s run through New York. The Sports Encounter saw the same pattern when he beat Botic van de Zandschulp in the quarterfinal, recovering from imperfect patches without allowing the match to become genuinely dangerous.
Alexander Zverev vs Karen Khachanov: Semifinal Score
| Player | Set 1 | Set 2 | Set 3 | Result |
|---|---|---|---|---|
| Alexander Zverev | 6 | 7 | 7 | Won |
| Karen Khachanov | 3 | 6 | 6 | Lost |
Final score: Alexander Zverev def. Karen Khachanov 6-3, 7-6(7), 7-6(6).
The Match Was Much Closer Than Straight Sets Suggest
A straight-sets semifinal can easily be read as control.
This one was closer to repeated escape.
Zverev finished with 107 total points. Khachanov won 104.
Three points separated them across 35 games.
Khachanov won more receiving points, landed a higher percentage of first serves and actually won a greater percentage of points behind that first delivery.
Zverev’s superiority appeared elsewhere.
| Statistic | Alexander Zverev | Karen Khachanov |
|---|---|---|
| Aces | 15 | 6 |
| Double faults | 6 | 3 |
| First serve % | 68% | 74% |
| First-serve points won | 75% | 78% |
| Second-serve points won | 72% | 57% |
| Break points converted | 2/3 | 1/2 |
| Tiebreaks won | 2 | 0 |
| Receiving points won | 29 | 33 |
| Total points won | 107 | 104 |
| Games won | 20 | 15 |
The most revealing number in the table may be Zverev’s 72% success rate behind his second serve.
Khachanov won 57% of his.
In a match where first serves were difficult to attack consistently, Zverev’s ability to protect the second delivery repeatedly kept Khachanov away from sustained pressure.
Zverev Took Control Early Without Needing His Best Tennis
The first set established the basic dynamic.
Zverev was the more dangerous server and created the cleaner opportunity on return. Khachanov competed well enough through the rallies, but one break was sufficient for the German to take the set 6-3.
That followed the broader pattern of Zverev’s tournament.
He arrived in New York as the top seed and reigning Roland Garros champion, but the path has not always been comfortable. He needed five sets in each of his first two matches before settling into increasingly efficient tennis.
The official US Open semifinal preview noted that Zverev had already spent 16 hours and 40 minutes on court before facing Khachanov, considerably more than his opponent.
Rather than looking worn down, Zverev has become more economical as the tournament has progressed.
The Sports Encounter tracked that progression from his straight-sets win over Luciano Darderi through the van de Zandschulp quarterfinal.
Khachanov Changed the Match in the Second Set
The semifinal became considerably more complicated after the opening set.
Khachanov raised the quality of his serving and stopped allowing Zverev easy access to return games.
His 74% first-serve percentage helped him keep points short, and when the first delivery landed, he won 78% of the resulting points.
Those are usually winning numbers.
They were not enough because Zverev prevented Khachanov from creating repeated pressure on his own second serve.
The second set eventually reached a tiebreak, where neither player gave much away. Khachanov came close to levelling the match, but Zverev eventually took it 9-7.
That was the point where the semifinal changed psychologically.
Khachanov had played a set good enough to win.
He left it two sets down.
The Second Serve Became Zverev’s Hidden Weapon
Zverev’s 15 aces will attract attention because they represent the obvious form of serving dominance.
His second serve mattered more.
Winning 72% of second-serve points in a Grand Slam semifinal is extraordinary protection, particularly against a player returning well enough to win 33 receiving points overall.
Khachanov had opportunities to apply pressure.
Zverev simply prevented too many of those opportunities from developing into break chances.
The result was a strange statistical balance: Khachanov returned enough points to remain competitive but not enough at the right moments to gain control.
Third-Set Tiebreak Decides Another Battle of Nerves
Khachanov refused to fade in the third.
He held serve repeatedly and forced Zverev through another set in which a single poor service game could have changed the direction of the semifinal.
Neither man produced it.
The set reached another tiebreak.
This was Khachanov’s final opportunity to force the match into unfamiliar territory. Win it, and Zverev would suddenly have to manage the physical and emotional consequences of a fourth set after already losing the statistical margins in several categories.
Zverev again survived.
He took the tiebreak 8-6 and closed the match without allowing Khachanov to convert competitive tennis into a competitive scoreline.
The difference was therefore not sustained superiority.
It was repeated superiority at the precise points where the scoreboard became irreversible.
Zverev Has Become the Player He Once Struggled to Be
Flushing Meadows carries uncomfortable history for Zverev.
In the 2020 final, he led Dominic Thiem by two sets before losing in five.
That defeat followed him for years as evidence that enormous physical tools and elite results did not automatically translate into a Grand Slam title.
The conversation changed at Roland Garros in 2026.
Zverev finally won his first major in Paris, then reached the Wimbledon final and has now returned to the championship match in New York.
According to the US Open’s pre-semifinal analysis, Zverev became only the ninth man in the Open Era to reach the semifinals of all four majors in one season.
The Sports Encounter examined how that consistency had already pushed him beyond a German benchmark when his quarterfinal victory gave him a record 23 Grand Slam match wins in 2026, surpassing Boris Becker’s 1989 mark for a German man.
The semifinal added another victory.
More importantly, it placed him one match from becoming a two-time major champion.
Khachanov’s Run Deserved a Better Ending Than the Scoreline Suggests
Khachanov leaves New York without the first Grand Slam final he was chasing, but his tournament remains one of the strongest runs of his career.
He entered the event outside the leading seeds and fought his way through a demanding draw.
His five-set victory over Learner Tien was among the toughest matches of his campaign. The Sports Encounter covered how Khachanov survived Tien in five sets before his quarterfinal against Alexander Blockx.
That quarterfinal ended prematurely when the injured Belgian was forced to retire with Khachanov leading 6-2, 7-5, 3-2.
Our report on Blockx’s painful exit detailed the difficult circumstances surrounding Khachanov’s path into the semifinal.
The official US Open noted that this was Khachanov’s third Grand Slam semifinal and his second at Flushing Meadows after reaching the same stage in 2022.
Against Zverev, he came closer than three straight sets suggest.
That may make the loss harder rather than easier to accept.
The Tiebreaks Explain the Entire Semifinal
There is a simple way to understand this match.
Remove the two tiebreaks and very little separated the players.
Add them back, and Zverev is in the final.
| Critical Category | Zverev | Khachanov |
|---|---|---|
| Total points | 107 | 104 |
| Break chances | 3 | 2 |
| Breaks converted | 2 | 1 |
| Tiebreaks | 2-0 | 0-2 |
Zverev won only three more points across the entire match.
He won five more games.
That is what converting pressure into scoreboard separation looks like.
Zverev’s 2026 Major Run Is Becoming the Larger Story
This result cannot be viewed only through the US Open.
Zverev’s entire Grand Slam season has changed his career.
He won Roland Garros.
He reached the Wimbledon final.
Now he is back in the US Open final for the first time since 2020.
His New York run has also unfolded inside one of the strangest men’s draws in recent memory. Novak Djokovic disappeared in the opening round, several established contenders followed, and Carlos Alcaraz was eventually stopped by Ben Shelton.
The Sports Encounter followed those shifts in our US Open upset and rain analysis, when the men’s field began opening much earlier than expected.
By the quarterfinal stage, opportunity had become one of the tournament’s defining themes. Our quarterfinal-race analysis examined how the exits of established names transformed both draws.
Zverev has now done more than survive that chaos.
He has become the last obstacle between one of two Americans and the men’s title.
Ben Shelton or Frances Tiafoe Awaits
Zverev will face the winner of the second semifinal between Ben Shelton and Frances Tiafoe.
That match guarantees an American finalist and gives Sunday’s championship match an entirely different emotional shape.
Shelton arrives after one of the tournament’s defining performances, eliminating Carlos Alcaraz in a five-set quarterfinal that finished deep into the New York night. The Sports Encounter broke down Shelton’s 3:33 a.m. victory over Alcaraz and the serving aggression that carried him through the match.
Tiafoe has taken a very different route. He needed a major comeback to escape Alex Michelsen, recovering from two sets down to keep his home Grand Slam alive. Our analysis of Tiafoe’s five-set comeback showed how much resilience has underpinned his return to the latter stages in New York.
The winner will have Arthur Ashe Stadium behind him.
Zverev will have something equally important.
Experience.
What Zverev Must Carry Into the Final
The semifinal revealed both reassurance and warning.
His serve remained a match-winning weapon. Fifteen aces and 72% of second-serve points won gave Khachanov almost no sustained path into Zverev’s service games.
The concern is that Zverev did not consistently dominate the neutral exchanges.
Khachanov won more receiving points and kept the final two sets close enough that one tiebreak swing could have changed the shape of the match.
Against Shelton, Zverev could face even greater serving pressure.
Against Tiafoe, the problem would be speed, crowd energy and a player who has repeatedly found ways to turn defensive positions into attacking ones.
Zverev therefore reaches the final with confidence but not comfort.
TSE Verdict
Alexander Zverev’s semifinal victory was a useful demonstration of where his game has evolved most.
The old version of Zverev could dominate for long stretches and still lose control when a set became emotionally compressed.
The 2026 version has increasingly done the opposite.
He does not need every statistical category.
He needs the scoreboard.
Against Khachanov, that meant surviving two tiebreaks, protecting his second serve at an elite level and converting two of only three break-point chances.
Three total points separated the players.
The match did not feel that close when it ended because Zverev repeatedly made those three points matter more.
That is why he is back in the US Open final.
