Former US Open champion Raducanu clocked the biggest win of her career by ranking when she defeated second seed and newly crowned Grass Court Championships Berlin winner Pegula in a marathon match lasting nearly three hours.

The 21-year-old rallied from a set down and saved match point in the second set tie-break to eventually level the match. Raducanu carried the momentum and adrenaline into the deciding set where she eventually served out the match at the third time of asking to record her first win over a top 10 player.

The youngster has well and truly found her spark during the grass court swing, having now backed up her semi-final appearance in Nottingham with a run to the final eight in Eastbourne.

“I’m very happy. Obviously Jessica (Pegula) is a really class opponent and she’s someone who’s very in form right now so it’s a great result for me and one that I need to enjoy and cherish. The way I handled certain situations in that match, I was really proud of.

“I don’t know if I’ve ever saved match point before and won. I’m obviously very proud of myself for sticking through because I was pretty much down the entire match and I fought through some really difficult situations with myself in the second set.

"Second chances don’t really come by and I think the regret of not fighting and trying my absolute best would’ve really haunted me after my match.”

Tomorrow, she'll face last year’s runner-up Daria Kasatkina in a bid to reach the semi-finals.

Meanwhile,1 Boulter produced a dominant display against world No.13 Ostapenko to punch her ticket to the quarter-final. The British No.1 capitalised on the Latvian’s uncharacteristic dip in service form after she racked up nine double faults and landed an average of 58% of first serves in.

Boulter broke Ostapenko five times across the two hour and five minute match to set up a quarter-final clash against Roland Garros runner-up Jasmine Poalini.

"Honestly I was just trying to slap it harder than she was" Boulter said. "She hit such a good ball, you never know what’s going to happen - it’s completely in her control and I just tried to be as aggressive and consistent as I could be and make her play every single ball. Today it paid off and I’m very happy."

British No.2 Dart also came through tough competition in the form of 2020 Australian Open champion Kenin. 

After clinching the opening set, Dart went on to fall the wrong side of the second set tie-break before dominating in the third to book her spot in the quarter-finals.

Speaking on her victory, she said “It was a really tough match. She’s a tough player, I was really pleased to get the win and regroup after that second set tie-break and come out firing in the third – I really battled my way through.”

She’ll now face a fresh challenge in 2021 US Open runner-up Leylah Fernandez who earlier eased to a straight sets win over Alison Krueger.

Amongst all the success in the women’s draw, it was also another landmark day for Billy Harris who continued his breakthrough summer after reaching back-to-back ATP Tour quarter-finals at the Rothesay International Eastbourne.

The 29-year-old showed his resilience to come back from a set down against fellow Brit Charles Broom, eventually prevailing 3-6, 6-2, 6-2. On being in the form of his life, Harris said “I feel like grass has been very good to me these last few weeks, I feel like I’ve got momentum in my game. I’m playing well on the grass and feeling good going into the next few matches.”

Harris will contest a spot in Friday’s semi-finals when he takes on Italian Flavio Cobolli tomorrow.
