US Open Day 13 Debrief — Friday, September 11, 2026: Shelton earns Sunday, Zverev owns the margins, and McEnroe backs America

Edge picked both finalists. Ben Shelton even arrived in the predicted four sets. Alexander Zverev needed one fewer.

That is satisfying without being the real story.

Shelton lost the opening set to Frances Tiafoe and then became the stronger player as the match grew heavier. Zverev beat Karen Khachanov 6-3, 7-6(7), 7-6(6) despite winning only three more points across almost three hours.

One finalist showed that his victory over Carlos Alcaraz was a beginning rather than an isolated great night. The other won the close sets that earlier versions of Alexander Zverev often found ways to surrender.

American tennis has its finalist. It does not yet have its champion.

Tiafoe did what he needed to do initially. He started quickly, involved the crowd and took the opening set 6-4.

Shelton’s response was the most impressive part of the night.

He did not immediately try to hit harder. He served more accurately, accepted long exchanges and gradually pushed Tiafoe behind the baseline. The match included rallies of 31 and 28 shots, hardly supporting the outdated description of Shelton as a serve followed by improvisation.

By the end, he had produced 20 aces and 47 winners while landing 75 per cent of his first serves. More importantly, he won 54 per cent of his second-serve points. Tiafoe managed only 38 per cent.

That was the sustainable difference.

Shelton broke late in the second set, survived an 11-minute game to secure the third and then remained patient through a tight fourth. At 5-6, Tiafoe fell 0-40 behind and ended the match with a double fault.

The final point was ugly. The preceding three hours and 15 minutes had already established the correct winner.

“I think I’ve grown up,” Shelton said. “I’m more mature, more focused.”

That is a better explanation than the aces. Shelton has always possessed frightening power. He has not always organised it this well.

Describing him as a huge serve with entertaining body language is now lazy analysis. The defensive improvement, return discipline and willingness to stay in neutral rallies are why he is playing his first major final.

Shelton also dedicated the victory to his late grandmother, whose support allowed his father Bryan to pursue tennis before coaching his son.

“This one is for her,” he said.

The history belongs beside the personal story. Shelton is the first Black American man to reach the US Open final since Arthur Ashe in 1972 and the first to reach any major singles final since MaliVai Washington at Wimbledon in 1996.

The Guardian’s live account and Shelton’s on-court interview

This was Tiafoe’s third US Open semifinal. He has won the opening set in all three and reached the final in none.

That is becoming difficult to dismiss as bad fortune.

Against Shelton, Tiafoe avoided the dreadful start that nearly eliminated him against Alex Michelsen. He returned aggressively, came forward and gave the crowd an immediate reason to participate.

Then Shelton improved and Tiafoe did not have a dependable second response.

The serve became more vulnerable, the forehand lost depth and too many neutral rallies ended with Tiafoe trying to create a winner from an ordinary position. His variety remained useful, but variety without consistent weight eventually becomes another way of asking the opponent to miss.

Tiafoe deserves credit for an excellent tournament and a much better season. He should not be comforted into pretending that another New York semifinal represents completion.

At 28, with three appearances in the final four, the next meaningful step is obvious. He has to reach the final.

The score makes Zverev’s semifinal look comfortable. The match was not.

Khachanov forced two tie-breaks, led the third-set breaker 5-2 and held two set points at 6-4. Across the entire match, Zverev won 107 points and Khachanov won 104.

Zverev nevertheless won in straight sets.

That is not luck repeated twice. It is what happens when the better player protects his serve, remains stable from the backhand side and forces an opponent to produce one more difficult forehand under pressure.

Khachanov’s forehand failed on both third-set points. Zverev then struck a 140mph ace and closed the match.

“Straight-set win, but anything but straightforward,” Zverev said.

Correct.

Zverev hit 15 aces, lost serve once and won 21 of 26 points at the net. The forward movement matters because passivity has ruined too many of his important matches. On Friday he did not wait for Khachanov’s errors from five metres behind the baseline. He applied pressure when the opportunity was available.

Tennis Now on Zverev’s semifinal victory

The draw has been kind to Zverev. He has reached the final without facing a top-eight seed, just as he won Roland Garros without meeting one.

That fact is relevant. It is not an indictment.

A favourable draw creates an opportunity; it does not win two tense tie-breaks. Zverev has now reached three consecutive major finals and is 24-2 in Grand Slam matches this season. He has not dropped a set since the second round.

For once, there is no need to invent a complaint about how the favourite did his job.

Official US Open semifinal report and match sequence

Friday’s preview selected Shelton and Zverev as the likely winners. Both won, with Shelton landing the exact four-set prediction.

Edge’s market signals were on the opposing players. Tiafoe was recorded at 3.60 against an estimated fair price near 3.43; Khachanov was available at 5.00 against a fair estimate close to 4.80.

Both underdogs lost.

That does not retrospectively make the prices incorrect. A price can underestimate an underdog’s chance and still produce a losing bet. But market language should never become a hiding place: neither signal returned anything on Friday.

The distinction remains important. The match picks identified the likelier winners. The signals identified two prices that appeared slightly too large. The first assessment went 2-0; the second went 0-2.

Friday’s Edge Market Wire preview

Before the semifinal, the Nothing Major panel broadly identified the match correctly. Sam Querrey preferred Shelton because he had “a little more firepower”. Steve Johnson argued that Tiafoe needed to start quickly and activate the crowd.

Tiafoe did both. He still lost.

That is what the preview could not fully measure: Shelton was able to improve inside the match without requiring Tiafoe’s level to collapse. The larger weapons mattered, but their organisation mattered more.

Nothing Major’s semifinal discussion

Andy Roddick’s more valuable observation after the Alcaraz match was that Shelton’s mental clarity had finally begun to match his physical gifts. Friday supported that view. Shelton lost a set, adjusted and played his best tennis after the initial excitement had passed.

John McEnroe has gone further. Before the semifinal, he said its winner would also win the US Open title.

That is a proper opinion, at least. It is also difficult to justify with the available evidence.

Zverev is 5-0 against Shelton. He owns the stronger backhand, the better return and vastly more experience in major finals. Shelton may beat him, but the American does not become the logical favourite because Arthur Ashe Stadium wants the drought to end.

John McEnroe’s US Open title prediction

McEnroe may prove correct. At the moment, Zverev remains the better pick.

Shelton has earned the opportunity American tennis wanted. Zverev has earned the favouritism many people would prefer to ignore.

The final will test whether Shelton can protect his second serve against a significantly better returner and prevent Zverev from controlling exchanges through the backhand. It will also test whether Zverev can remain aggressive when 24,000 people are openly waiting for him to fail.

Zverev has already supplied the line for Sunday.

“Hopefully I can make the American dream not come true.”

Good. The final does not need artificial friendliness.

Shelton has the serve, the crowd and the tournament’s best victory. Zverev has the matchup, the experience and five previous wins over him.

America has its finalist.

On Sunday, it needs an upset.
