Miami Open: Cameron Norrie, Katie Boulter & Fran Jones knocked out as British hopes in singles over

Elsewhere in the women’s draw, American Coco Gauff dropped the first set but recovered to beat Alycia Parks 3-6 6-0 6-1 in the third round, while Amanda Anisimova was a 6-4 6-2 winner against Yuliia Starodubtseva and Victoria Mboko earned 6-1 7-5 victory over Anastasia Zakharova.

Former world number one Naomi Osaka, however, said she was trying to balance the tennis schedule with being a mother after she was beaten 7-5 6-4 by Australia’s Talia Gibson in their second round match.

“I feel like this also is a dilemma for me,” said Japan’s Osaka, who returned to the WTA Tour in January 2024 after a 15-month absence around the birth of her daughter in July 2023.

“For me, my daughter is very important, and I want to be a mom. I want to be the best mom I can, but sometimes I feel like I know what I have to do to become a really good player, and it’s very difficult.

“Because for me, I want to win titles and I want to be the best player I can, but if I have to sacrifice having a lot of time with my daughter, I’d rather not do it.”

In the men’s draw, world number two Jannik Sinner comfortably beat Damir Dzumhur 6-3 6-3, while Alexander Zverev beat wildcard Martin Damm 6-2 6-4.

Zverev will play Marin Cilic, who was a 2-6 6-4 7-6 (9-7) winner against Brandon Nakashima, in the third round.

Home favourite Ben Shelton did not progress as he suffered a surprise defeat by Alexander Shevchenko, who claimed a 6-7 (3-7) 7-6 (7-3) 6-3 win against the world number nine.
