• Sabalenka on brink of trifecta after blitzing Pegula

• Rybakina rallies past Gauff to reach first US Open final

First set: Sabalenka 1-0 *Pegula (*denotes next server)

A strong start for Sabalenka, who wins the first game with ease. She gets an ace on the second point of the match and keeps the rallies short to hold.

Sabalenka made quick work of Iatcenko in the second round, while Tiafoe, Tsitsipas, Pegula and Muchova were among the other notable winners

And Nakashima breaks too – he’s hitting it hard off both wings and I wonder if he’s in the process of finding a new level. The first few times I watched him, I thought he had a bit of something and, real talk, I thought he’d be better by now than he is. But I really like what I’m seeing from him and, as we know, progress isn’t always linear.

It’s a good start for Medvedev, Gorzy – who saved five match points in round one – tamely ceding serve to 15.

Alex Eala has become the Philippines’ biggest sporting star since Manny Pacquiao. Now the 21-year-old’s traveling army of fans have descended on Flushing Meadows

The crowd began to swell in Louis Armstrong Stadium a half hour before 2pm. A fair number of fans were probably there to see Taylor Fritz and Terence Atmane practice, but it was the session after theirs that was the headline attraction on the Friday of the US Open’s fan week. The blue, red and white throughout the stands, spotted on bucket hats and posters and basketball jerseys and flags, signaled who these people were here to see.

This has been the year of Alex Eala, the 21-year-old sensation who has taken the tennis world by storm. At No 18, she is the Philippines’ highest-ranked player ever, its biggest sports celebrity since Manny Pacquiao. The country’s president hosted a reception to celebrate her success, and called for a national celebration after she won her first tour-level title last month at the DC Open. Forbes estimates Eala’s off-court earnings for the past year to exceed $5m, plus $1.7m in prize money, and her agent predicts she will be the world’s second-highest-paid female athlete by 2027.
