That’s all for tonight. Thanks as always for following along with us and be sure to read Tumaini Carayol’s full report off tonight’s twinbill.
“She played incredible tennis,” Sabalenka says of Keys in her on-court interview. “It was just another level. Somehow – I don’t know how actually – I turned around this match and I won it. It really means a lot being in the final of the US Open for the first time. It really means a lot to me.”
She’s asked about Saturday’s final against Coco Gauff and offers high praise to the American star.
“She’s an unbelievable player,” Sabalenka says. “She’s playing really incredible tennis here at the US Open. The crowd will be supporting her a lot. That’s something I expect. This is nothing crazy. I’ll just go there and just do everything I can. I’ll be there and I’ll be fighting for every point. I’ll do my best.”
Sabalenka wins 0-6, 7-6, 7-6 to reach US Open final!
Match tiebreaker: Keys 5-10 Sabalenka
Sabalenka slots a drop-shot winner on Keys’s serve for match point. The American has one more serve at 3-9 and saves the first match point with a big first serve. Then saves a second match point on Sabalenka’s serve. But Sabalenka converts the third when Keys sends a return past the baseline! It’s all over! Sabalenka has completed the comeback!

Third set: *Keys 6-0, 6-7, 4-4 Sabalenka (*denotes next server)
A whisper of a chance for Keys after Sabalenka double-faults before falling behind 15-30, then 30-40. A golden break-point opportunity for the American veteran. And Sabalenka saves it with brio, stepping into the frontcourt to crush a backhand winner early in a rally, punctuating the winner with a resounding “Come on!” Keys earns a second break point and Sabalenka saves that, too, with a backhand volley winner. From there Sabalenka escapes with the hold thanks to a Keys unforced error followed by a huge backhand that her opponent can’t return. Danger averted thanks to a pair of very strong points at the net, which hasn’t always been a vicinity where Sabalenka has thrived.

Keys breaks in sixth game of third set!
Third set: *Keys 6-0, 6-7, 4-2 Sabalenka (*denotes next server)
Just when it looked as if Keys was ready to fade, Sabalenka makes back-to-back unforced errors off her forehand early in baseline rallies to go down love-30 on her serve. And now Sabalenka double-faults for the third time for love-40. Three break-point chances for Keys. Sabalenka erases the first with a 103mph ace down the center, but Keys converts the second with a cross-court forehand from the baseline that Sabalenka overcooks on the return. Keys has drawn first blood in the decider and finds herself, again, two games from the final.
Third set: Keys 6-0, 6-7, 3-2 Sabalenka* (*denotes next server)

Third set: *Keys 6-0, 6-7, 1-1 Sabalenka (*denotes next server)
A commanding service game for Sabalenka, who follows a backhand winner early in the rally with a 114mph service winner then an ace down that middle that clocks at 120mph, her fastest serve of the night. After making a couple of errors, the Belarusian closes the show with a second-serve service winner at 106mph, her fastest second serve of the match. Statement made.
Third set: Keys 6-0, 6-7, 1-0 Sabalenka* (*denotes next server)
Keys’ movement doesn’t look impaired coming out of the MTO, but the error-strewn play that’s gripped her tennis since midway through the second set has not subsided. She’s just gone down 15-30, then 30-40 on her serve after mixing in her 24th, 25th and 26th unforced errors. A break-point chance for Sabalenka and a huge moment for Keys. And Sabalenka squanders it, failing to capitalize on a 68mph second serve and misfiring on a backhand for deuce. From there Keys serves her way out of trouble to hold in the opening game of the third.
Madison Keys is taking a medical timeout. She’d called for the trainer immediately after the second set and it was determined she needed further treatment. It’s unclear whether it’s for a hip or thigh ailment. Sabalenka follows her off court, where the conditions have softened considerably from over the past few days but are still a touch uncomfortable at 80F (27C) with 70% humidity.

A huge moment for Keys, who is assured a trip to the US Open final if she can hold her serve twice. She opens with a forehand winner, then hits an extraordinary angled backhand from outside the court that Sabalenka can’t return. She then pounds another big serve that Sabalenka can’t handle for 40-love, before coming to net early in the rally on the next point and dumping a backhand volley into the net for 40-15. No problem. Keys promptly fires in a 107mph first serve that Sabalenka fails to return to close out the hold. One game from the final.

Second set: Keys 6-0, 4-2 Sabalenka* (*denotes next server)
It’s hardly a must-hold for Keys according to the scoreline but it sure feels like one. After three straight breaks it would be quite a relief for the American to hold and keep the pressure on Sabalenka by maintaining her lead. Sabalenka doesn’t make it easy, hitting one forehand winner for love-15, then another for 15-30. Keys wins the next two for game point but follows with an unforced error for deuce. From there Keys digs in and escapes with the hold. She’s two wins away from her second major final and first in six years.

A shaky start for the soon-to-be-world No 1. She wins the opening point, but watches as Keys strikes a return winner, volley winner and baseline winner – all with the forehand – for 15-40. Two early looks at a break point for the American. Sabalenka saves the first with a 93mph second-serve ace out wide, then the second when Keys nets a backhand from the baseline at the end of a muscular nine-shot rally. Deuce. Sabalenka then misfires again from the baseline for a third break-point chance ... and she double-faults! Oh dear. It’s a gift-wrapped break for Keys to start this second US Open semi-final.

Keys and Sabalenka have taken the court for tonight’s second semi-final. This is the fourth meeting betwen the two with Sabalenka having taken two of the previous three, most recently a 6-2, 6-4 win in this year’s Wimbledon quarter-finals.
The players meet at the net for the coin toss. Keys chooses heads. It’s tails and Sabalenka elects to serve. We should be under way in the next few minutes.
As we wait, the USTA has released the following statement on the stadium protesters that caused the earlier delay:
Following the first game of the second set in the Gauff-Muchova match, play was halted due to a protest conducted by four spectators.
Three of the four protesters were escorted out of the stadium without further incident. The fourth protester affixed their bare feet to the floor of the seating bowl. Due to the nature of this action, NYPD and medical personnel were needed in order to safely remove this individual from the stadium.
The four protesters were taken into NYPD custody.
In total, 49 minutes elapsed before play resumed.

“Some of those points it was so loud and I don’t know if my ears are going to be OK,” Gauff says. “This is crazy. I grew up watching this tournament so much, so it means a lot to be in the final. A lot to celebrate. But the job is not done, so hopefully you guys can back me on Saturday.”
Gauff is asked what she will be doing for the second match between Madison Keys and Aryna Sabalenka.
“Press, treatment, watch some anime,” she says. “No, literally today I watched four or five episodes of My Hero Academia before I played. I may watch some of the match, maybe not. I haven’t even thought that far ahead to be honest.”

Muchova double-faults for only the second time all night to go down love-15. She wins the next point for 15-all, but Gauff follows with a blistering forehand early in the rally that Muchova can only get a frame on for 15-30. Then Muchova sends a forehand well past the baseline for 15-40. Two more match points for Gauff. And Muchova erases the first with a forehand winner on the run down the line for 30-40. A third match point for the American ... and Gauff goes for the win on a cross-court forehand on the 13th shot off a grueling baseline rally but just misses the line. Deuce! Another lengthy baseline exchange follows and this time Muchova blinks, missing on a backhand. A fourth match point for Gauff and Muchova saves that one, too, with a vicious forehand return winner. Gauff earns a fifth match point and Muchova saves it again!

Here’s another view of the protesters. Two of them were removed while one still remains, causing the ongoing suspension of play. “They said they’re on the phone negotiating,” Gauff could be overheard saying before retreating into the tunnel. “Like this is a hostage situation.”

Both players have left the court during the ongoing delay. A very unfortunate turn for Gauff, who had momentum to burn after winning the first set and holding to open the second. A user on X, formerly known as Twitter, has shared footage of the three protesters in the upper deck.

Play stopped during second set due to protesters
Chants of “Kick them out! Kick them out!” are ringing across Arthur Ashe Stadium. Gauff is standing behind the baseline, hitting serves to stay loose. Muchova is still in her chair having been given tablets by medical staff, who have retreated to the tunnel. The stoppage has lasted more than 10 minutes at this point. Some of protesters appear to have been physically removed from the stadium, but there is one who has refused to budge from his seat and is being surrounded by security.

The match has been paused due to a disruption in the upper mezzanine. Protesters, apparently. The tournament referee and other officials are on the court speaking with the chair umpire as security officials have been dispatched upstairs. Both players are at their chairs in the meantime and Muchova has summoned a physio.

Second set: Gauff 6-4, 1-0 Muchova* (*denotes next server)
Gauff holds comfortably to open the second set. Gauff made three times as many unforced errors in the opening set (12, all but one off the forehand) as winners (four), but Muchova’s total capitulation at the finish line made the difference.
Gauff wins first set, 6-4!
Gauff breaks in 10th game of first set!
First set: Gauff 6-4 Muchova
And just when Muchova is poised to really put the pressure on Gauff, the 10th seed unravels spectacularly. She goes down love-40 and triple set in the blink of an eye after an unforced error from the baseline, another at the net, then a biffed forehand. Gauff has three points to capture the set but needs only the first when the generous Muchova botches a backhand for her 17th unforced error (against only three winners). First set to the American after 42 minutes!

Muchova breaks in ninth game of first set!
First set: Gauff 5-4 Muchova* (*denotes next server)
Well, well, well. Gauff gets a second opportunity to serve for the set and wins the opening point after Muchova donates her 14th unforced error. But the Czech improbably rattles off four quick points from there for her second break of serve, helped along by a flurry of Guaff misfires. We’re back on the serve in the first and Muchova will serve to stay in the set after the change of ends.
First set: *Gauff 5-3 Muchova (*denotes next server)
Muchova fights her way to another hard-fought hold. She’s made only two winners against 13 unforced errors, but she’s clearly raised her level as the set has unfolded.
Muchova breaks in seventh game of first set!
First set: Gauff 5-2 Muchova* (*denotes next server)
Gauff strikes a clean backhand winner, but quickly goes down 15-40 after a couple of errors. Two break-point chances for Muchova but she needs only one of them: Gauff makes another unforced error off her backhand early in a rally and she’s been broken for the first time in the match.

Gauff breaks in sixth game of first set!
First set: *Gauff 5-1 Muchova (*denotes next server)
An error-strewn service game for the nervous Muchova, who goes down love-30 then 15-40. A second break point for Gauff and she rips a wicked forehand early in the rally that Muchova can’t return. The American is up a double break, having won 22 points to Muchova’s nine, and will serve for the first set.
First set: Gauff 4-1 Muchova* (*denotes next server)
Gauff breezes through another stress-free service game, holding at love to maintain her lead. She’s won eight straight points on her serve (and 12 of 14 on the night overall).
First set: *Gauff 3-1 Muchova (*denotes next server)
Another tight service game for Muchova, who has barely got half of her first serves in. But she holds from love-15 down, capping it with a 104mph ace down the middle to get on the board.

First set: Gauff 3-0 Muchova* (*denotes next server)
Muchova puts a bit of pressure on Gauff’s serve, hitting a forehand winner then forcing Gauff into an error with another crisp forehand. But Gauff wins four straight points capped by a 101mph unreturnable serve to hold from love-30 down and stay ahead in the first set.

Gauff breaks in second game of first set!
First set: *Gauff 2-0 Muchova (*denotes next server)
Muchova is under immediate pressure on her serve at 15-30. Gauff makes her first unforced error for 30-all, but follows it with another lob winner for 30-40 and her first break-point chance. And she converts! Muchova flubs a backhand on the sixth shot of a baseline rally to hand Gauff the early advantage in the opener!
First set: Gauff 1-0 Muchova* (*denotes next server)
A great start for Gauff. She wins the opening point with a clean backhand winner to settle a 15-shot baseline rally, then wins the next two on a pair of Muchova unforced errors off the backhand side, then hits a perfect lob winner over her onrushing opponent to close out the love hold and send this partisan crowd into a roar. It’s loud!
The players have emerged from the tunnel after their pre-match interviews. Gauff was asked what she’s learned about herself over her wildly successful North American hard-court season: “That I’m able to find a way and I’m out there having fun on the court. That’s all that matters.”
Chair umpire Alison Hughes oversees the coin toss. Gauff calls heads. It’s tails and Muchova elects to receive first.
The players are going through their warm-ups and we’ll pick it up with game-by-game coverage from here.
Prelude
Hello and welcome to Arthur Ashe Stadium for tonight’s US Open women’s semi-final doubleheader. We’ve got a jewel of a twinbill ahead with Coco Gauff and Karolina Muchova meeting in the opening match followed by Madison Keys and Aryna Sabalenka in the nightcap. The Arthur Ashe Stadium crowd will no doubt be pulling for the prospect of an all-American final on Saturday, but the sixth-seeded Gauff and 17th-seeded Keys will each have their hands full tonight with opponents more than capable of playing spoiler.
First up it’s Gauff against Muchova, the 10th-seeded Czech who reached her first career grand slam final earlier this year at Roland Garros. Their lone career meeting came only three weeks ago in the Cincinnati final, which the American teenager won in straight sets to capture the biggest title of her career to date.
Gauff, the youngest player to reach the US Open semi-finals since Serena Williams in 1999, became the betting favorite to win the tournament after top-seeded Iga Swiatek’s fourth-round ouster, but there will be heaps of pressure on those 19-year-old shoulders at tonight’s penultimate hurdle and it will be fascinating to see how she handles it.
Plenty more to come from another sweltering night at Flushing Meadows, where the players due on court for their warm-ups in about 10 minutes.
Bryan will be here shortly. Here’s Tumaini Carayol’s lookahead to Friday’s twinight doubleheader of US Open men’s semi-finals.
