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.
