Katie Boulter and Sonay Kartal both produced impressive victories at either end of a record-breaking day for British players at Wimbledon.

Former British number one Boulter took to Centre Court in the evening and secured a rare victory over a top 10 player as she beat Spain’s Paula Badosa 2-6 6-3 4-6.

Earlier, Kartal was the first player through from the 14-strong British contingent in action on day one with victory over 20th seed Jelena Ostapenko.

In total, seven Britons in the men’s and women’s draw progressed to the second round on day one, making it the most successful day for British players at Wimbledon in the Open era.

Boulter, 28, and Kartal were joined by British number one Emma Raducanu – who beat compatriot Mimi Xu – Cameron Norrie, Arthur Fery, Oliver Tarvet and Billy Harris.

“It’s incredible with so many Brits in the draw,” Raducanu, 22, said.

“I think it’s great for the spectators, too, to have so many Brits to follow in the draw. As we win matches, it’s more and more exciting.”

Boulter will next face lucky loser Solana Sierra of Argentina.

“I played some really good stuff and I’m happy to be through to the next round,” Boulter said.

“I played a lot of matches later where I started out great and then kind of let it slip, I did one at Queen’s which hurt me a lot. I just tried to compete today and fight.”

On a sweltering day at SW19, Kartal toppled the former French Open champion 7-5 2-6 6-2 to book her place in the second round.

Kartal, 23, was one of 10 British women in action at the All England Club – the most since 1992.

She had to come from behind to win the opening set on a lively court three.

But a dominant deciding set secured her progression to round two for the second time in her career, following a breakout tournament at last year’s Wimbledon where she reached the third round.

“That was by far one of the toughest matches I’ve played,” she said after the win, her third over a top-20 player this year.

“I would say I struggle against the big hitters. I’ve made a conscious effort this year to play the bigger matches and put myself under the most pressure out on court.

“I knew I wouldn’t get the results straight away but that it would eventually pay off, and that’s what happened today.”
