Not many people expected Mertens to win against Kenin but she did and she found herself in the US Open quarterfinals. Following the match, she spoke about what she did to achieve it:

"I played pretty aggressively from the first ball, and that's pretty necessary against her because she's a great player who can hit a lot of great angles. I tried to step into the court, and thankfully my first serve was working, so that was a big advantage."

This was the 3rd time Mertens clashed with Kenin but unlike the first two encounters it was she won them. She explained what helped her this time around:

"It's always good to watch matches against players you've lost to because you know you have to do better. I actually watched the Wuhan match, but most importantly I tried to stay focused, and that's what I did tonight."

When asked what this victory means for her she said:

"It means a lot because a lot is going on in the world and I'm just glad to be back and playing matches, doing what I love."
