Harriet Dart ‘a little bit in shock’ after stunning Daria Kasatkina at US Open

Delight for Harriet Dart

Harriet Dart pulled off the best result of her career by upsetting in-form 10th seed Daria Kasatkina in the first round of the US Open.

The British No 2 had never previously won a main draw match at Flushing Meadows and looked to have a very tough draw on her hands against Russian Kasatkina, who is ranked ninth after winning the Championnats de Granby in Canada title on Saturday.

But Dart battled superbly in hot conditions on Court 12, recovering from a shaky second set and then coming from behind in the third to claim a 7-6 (10-8), 1-6, 6-3 victory.

Dart, 26, is enjoying the best season of her career having made the jump into the top 100 and picked up some eye-catching wins, including over Elina Svitolina on her way to the fourth round in Indian Wells.

She also had a strong grass-court season as she reached the quarter-final of the Eastbourne International, but the Londoner had never previously defeated a top-10 player.

There were 10 breaks of serve in the opening set, which Dart edged on a tie-break after saving two set points.

Kasatkina, who reached the French Open semi-finals earlier this year, hit back in the second set, pushing Dart well behind the baseline, and looked in control early in the third.

But Dart kept fighting and earned her reward, holding her arms aloft after clinching her first match point to set up a second-round clash with Hungary’s Dalma Galfi with the winner to face either 18th seed Veronika Kudermetova or Maryna Zanevska in the third round.

“To be honest I’m a little bit in shock right now,” she told Amazon Prime Video. “Physically I don’t feel great but I really just tried to stick at it and push through, and I can’t believe I got the win.”

The 26-year-old is currently sitting at No 88 in the official WTA Rankings, but she is now projected to rise to No 80 after her first-round victory. With Emma Raducanu in danger of slipping down the rankings if she fails to successfully defend her US Open title, Dart could find herself becoming British No 1 by the end of the tournament.

Ons Jabeur, though, is the headline act in the section and the fifth seed from Tunisia defeated Madison Brengle 7-5, 6-2 to set up an encounter against American wildcard Elizabeth Mandlik, who beat Tamara Zidansek 7-5, 6-7 (3-7), 6-3.
