Britain’s second seed Harriet Dart scored the biggest win of her career by eliminating 10th seed Daria Kasatkina, while seventh seed Simona Halep was knocked out by Ukrainian Daria Snegur.
Dart had never won a major draw match at the US Open and looked set to face a tough task against Russian ninth seed Kasatkina after winning the WTA title in Granby on Saturday.
But Dart fought superbly in the hot conditions on Court 12, recovering from a shaky second set and then coming back from behind in the third to take a thrilling 7-6 (10-8) 1-6 6-3 win.
Halep was stunned by qualifying
Snigor, who was the 2019 Wimbledon girls’ champion, wore a ribbon in the colors of the Ukrainian flag across her chest and made a heart shape around it at the end of her 6-2 0-6 6-4 victory.
Halep went to the event as one of the favorites after winning the big warm-up title in Toronto and back in the top 10, but despite threatening to return from 5-1 in the decider, Snigur managed to cross the streak.
“I’m very, very, very nervous but I tried to do my best,” she said in an interview in court. “For Ukraine, and for my family, I want to thank you all.”
Snegur’s father is with her in New York but her mother is at home in Kyiv, where the young woman is no longer able to train after the center where she trained was bombed in the war.
“Of course, the situation is bad,” she said. “I try to do my best for Ukraine, I try to support my country. It is not that easy because the war is going on. Sometimes it is impossible to play but I try to do my best because I want to live in Ukraine.
“Before the war I trained in Kyiv but Russia bombed my base so before the US Open I trained in Riga with my coach but I don’t have a base where I can train every time.
“I think people (Ukrainians) enjoyed my game because I had so many messages. I didn’t understand what happened. I will try to understand that tomorrow because I think it was the best match of my career.”
Gough defeats Ash to advance to the second round
American Coco Gauff entered the second round with a comfortable 6-2 6-3 victory over France’s Julia Gangin.
Gauff, seeded 12th and a home favorite, captivated the crowd at Arthur Ashe Stadium behind her in strength as she wrapped up the match in 79 minutes on the back of a strong first serve.
“I’m very excited because this is my first win against Ashe. I think this is my fourth game here on this court and this is my first win,” she said.
The 18-year-old, the French Open runner-up earlier this year, fired eight aces and dropped just two points on her first serve.
