Ever since Coco Gauff made her remarkable run at Wimbledon, tennis fans around the country have been anxiously awaiting the opportunity to see her play again. The 15-year-old played in the Citi Open in late July through early August, but the US Open will give her a much larger stage to shine on once again.

While Gauff had a disappointing showing in the women’s singles draw at the Citi Open, the women’s doubles draw was a very different story. Coco Gauff enjoyed success with her 17-year-old teammate Caty McNally, and the two will team up once again as a wild card team at the US Open.

Gauff and McNally won the doubles title at the Citi Open

Coco Gauff and Caty McNally were added into the Citi Open doubles bracket in Washington D.C. as a wild card team. They made the most of that opportunity with a dominant run through the tournament, never dropping a single set en route to the women’s doubles title. It was the first WTA title of both women’s careers.

The Citi Open wasn’t the first time that the Gauff and McNally, who have earned the team nickname “McCoco”, have competed together. The two teamed up in the US Open junior doubles event last September and went on to win that tournament, solidifying themselves as two of America’s top young tennis prospects.

The team is oozing with confidence heading into the 2019 US Open, this time in the pro bracket. “I think our goal is to win it, and I think we’re not going to expect anything, we’re just going to expect to play our best,” Gauff said after their Citi Open win. “But I’m not going to say let’s see how far we can go, because I think, to be honest, the way we’re playing, we can go as far as we want.”

The two teammates will also compete in the singles bracket

Caty McNally’s 2019 US Open singles run began on Monday, August 26, when she defeated Timea Bacsinszky 6-4, 6-1 in the first round. The women’s singles bracket isn’t doing McNally any favors as her next opponent is Serena Williams, who handily defeated Maria Sharapova 6-1, 6-1 on Monday.

Coco Gauff has her first-round matchup today against 18-year-old Anastasia Potapova. Potapova its ranked 72^nd in the WTA singles rankings and is coming off of a solid run into the Round of 16 in her last tournament at the Bronx Open earlier this month. Gauff will be looking to bounce back from a first-round exit in the Citi Open where she lost to Zarina Diyas.

The sky is the limit for these two young stars

Serena Williams still appears to have plenty of tennis left in her, but at 37 years old she can’t stay on top of the tennis world for much longer. And she doesn’t have a clear heir apparent; nine different women have won a Grand Slam singles title since the start of the 2017 season.

Are Coco Gauff and Caty McNally destined for tennis greatness? It is far too early to tell as both are just now writing the first chapters of their story. But those chapters have been quite promising so far, and seeing how far these two are able to go together in the doubles bracket will be one of the most exciting stories to watch in this year’s US Open tournament.
