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.

• Australian tested positive at event in June

• Kyrgios and Tsitsipas have clashed in the past

Stefanos Tsitsipas says he is not surprised that Nick Kyrgios was suspended from tennis for taking cocaine.

“Pretty much expected, to be honest,” Tsitsipas said. “I am surprised it came so late, though.”

• Spaniard beats Roman Safiullin 6-4, 6-4, 6-4

• Alcaraz has not played since April with wrist injury

As Carlos Alcaraz edged closer to the conclusion of his first singles set in more than four and a half months, like so many times in his career instinct took over. Up 5-4, 30-15 in set one, Alcaraz swept forward to the net behind a precise wide serve and, when his opponent Roman Safiullin responded with a dipping backhand return directly to his feet, Alcaraz delicately pushed a half-volley over the net for a winner.

It was a gorgeous shot, a perfect example of the creativity and feel trademarked by Alcaraz that has been missed throughout his extended injury layoff. That touch of genius was followed, predictably, by a wide smile, a quick hold and a comprehensive victory as the Spaniard returned to competition with a stellar 6-4, 6-4, 6-4 win against Safiullin.

• Reigning singles champion beats Camila Osorio 6-2, 6-4

• Men’s 10th seed Arthur Fils beaten by Stefanos Tsitsipas

Aryna Sabalenka said she is determined to look ahead, rather than dwell on a difficult past few months, after beginning her US Open title defence with a 6-2, 6-4 victory against Camila Osorio.

“The good thing for me is not looking back no matter what, if it’s good or bad, because I feel a good result can also stop you from performing well because you’re basically focusing on the past,” Sabalenka said. “I never look back. If I win the tournament or lose the tournament, today is a new day, and I have to stay in the moment.”
