Coco Gauff heralds a new dawn for American tennis

Coco Gauff is still a teenager, after all, and so it should surprise no one that she was on her phone in the locker room, scrolling through social media, right up until 10 minutes before heading out on court for the US Open final.

What the 19-year-old from Florida was reading, she would say later, were various comments, negative ones, “saying I wasn't going to win today; that just put the fire in me.”

As a pro athlete from a young age, as someone of whom greatness has been expected by some and doubted by others, Gauff has always taken it all in and kept moving forward, trying to learn from each setback.

And now, at a tournament she used to visit as a kid to see her idols, Serena and Venus Williams, Gauff is a Grand Slam champion herself and a certified star.

Setting aside a so-so start on Saturday, Gauff surged to a 2-6, 6-3, 6-2 victory over the soon-to-be-No. 1 Aryna Sabalenka in the final at Arthur Ashe Stadium, delighting a raucous crowd that backed her from start to finish.

When Gauff walked into her news conference — phone in hand, of course — she noticed that a large screen on the back wall was rotating pictures of her from the match. So she tucked her new silver trophy under one arm and used the other hand to snap a selfie with those photos in the background.

“Right now I’m just feeling happiness and a very, very small bit of relief,” she explained. “Because honestly, at this point, I was doing it for myself and not for other people.”

Gauff is the first American teenager to win the country’s major tennis tournament since Serena Williams in 1999. If last year’s US Open was all about saying goodbye to Williams as she competed for the final time, this year’s two weeks in New York turned into a “Welcome to the big time!” moment for Gauff.

Famous people were coming to watch her play, including former President Barack Obama, who was among those sending congratulatory wishes on Saturday.

Also, Gauff and her parents received a congratulatory phone call from President Joe Biden, who was in New Delhi for the Group of 20 summit.

Gauff burst onto the scene at 15 by becoming the youngest qualifier in Wimbledon history and making it to the fourth round in her Grand Slam debut in 2019. She reached her initial major final at last year’s French Open, finishing as the runner-up to Iga Swiatek, a loss that stung.

“I watched Iga lift up that trophy, and I watched her the whole time," Gauff recalled. "I said, ‘I’m not going to take my eyes off her, because I want to feel what that felt like for her.’”

Another down moment came this July at the All England Club, where she exited in the first round. Since then, she has won 18 of 19 matches, and now 12 in a row, while working with a new coaching pair of Brad Gilbert and Pere Riba.

The No. 6-seeded Gauff did it Saturday by withstanding the power displayed by Sabalenka on nearly every swing of her racket, eventually getting accustomed to it and managing to get back shot after shot.

Gauff broke to begin the third set on one such point, tracking down every ball hit her way until eventually smacking a putaway volley that she punctuated with a fist pump and a scream of “Come on!”

Soon it was 4-0 in that set for Gauff. Didn't take long for her to close it out, then drop to her back on the court, before climbing into the stands to find her parents.

“You did it!” Gauff's mom told her, both in tears.
