Jennifer Brady dumps former champion Angelique Kerber out of US Open

Brady bullied her German opponent from the back of the court during a 22-minute first set.

The second was closer, and there was concern for Brady when she went off-court after five games and returned with her left thigh strapped.

The 28th seed needed more treatment at the changes of ends but she held things together mentally and physically to march across the finish line.

Brady said: “Wow, it feels great, I’m so happy. I played a spectacular first set. The second set I really just tried to focus on every single point. I was getting a little frustrated, I felt a little pain in my leg, but I just really wanted to close it out in two sets.”

Brady is good friends with Sofia Kenin, who took many people by surprise by winning the Australian Open title, and sees no reason why she cannot became the latest in a string of first-time women’s slam champions.

“I think right now the women’s game is so deep,” she said. “Anybody can win a major. It’s just a matter of how the draw really pans out.

“I think seeing the younger players or other players winning majors and not just the same person, I think it brings a different fire or fuel for other players. They see that and they’re like, ‘OK, if they win, I can also win’.”

In the last eight, Brady will play another first-time New York quarter-finalist in 23rd seed Yulia Putintseva, who defeated eighth seed Petra Martic 6-3 2-6 6-4.

Meanwhile, Timea Babos has spoken of her devastation and anger after she and doubles partner Kristina Mladenovic were forcibly withdrawn from the tournament on Saturday.

Mladenovic had been operating under increased restrictions following contact with Benoit Paire, who tested positive for Covid-19 last weekend, but the intervention of public health officials moved the goalposts.

Adrian Mannarino was allowed to play his singles match on Friday after lengthy discussions but Mladenovic and Babos were prevented from playing their second-round match the following day.

Writing on Instagram, Babos said: “I got home. I’m sitting here in my kitchen and crying.

“I haven’t really had time for anything so far, so now I’m just starting to realise what happened and I just don’t understand. It’s terribly unfair all over, I don’t see any acceptable reason why this should have been the case.”
