The action is heating up in the men’s, women’s and mixed events at the US Open. Doubles Take looks at the big news in the Big Apple.

Rain delayed the start of doubles play at the tournament, and at the beginning of the second week, the skies have opened up once again, which could lead to another backlog of matches.

In between that, though, one team has taken the tournament completely by storm.

American teenagers Cori Gauff and Caty McNally advanced to the round of 16 at the tournament, with their latest win coming against last year’s Wimbledon finalists Nicole Melichar and Kveta Peschke. 

“McCoco” didn't drop a set in Washington this summer, when they captured their first title and they won every match at last year’s junior US Open event in straights.

Their opponents on Monday were as tough as it gets: Ashleigh Barty—who won the title last year with CoCo Vandeweghe—and Victoria Azarenka, both of whom will be motivated to stick around after earlier-than-expected singles losses. Barty and Azarenka taught the teens that they still have a ways to go with a 6-0, 6-1 demolition. They join such doubles standouts as Aryna Sabalenka/Elise Mertens and Gabriela Dabrowski/Yifan Xu in the quarterfinals.

On the men’s side, Robert Farah and Juan Sebastian Cabal, the top seeds, are still alive and will face the No. 13-seeded Dutch team of Robin Haase and Wesley Koolhof next. The No. 2 seeds, though, are out: Lukasz Kubot and Marcelo Melo fell to Leonardo Mayer and Joao Sousa in the third round. Those two face French Open champs Kevin Krawietz and Andreas Mies, finally experiencing wins again after struggling since Roland Garros.

Jamie Murray and Neal Skupski, the No. 15 seeds, are having the best tournament of their brief time together and have advanced to the quarterfinals. Murray’s pulling out all the stops in helping them get this far. 

Murray and Bethanie Mattek-Sands are still alive in mixed doubles. They squeezed past Dabrowski and Mate Pavic in a battle of recent Slam winners to reach the semifinals.
