Melbourne: Coco Gauff's conqueror Sofia Kenin reached the semi-finals of a Grand Slam for the first time Tuesday as the American ended the historic run of Tunisian Ons Jabeur at the Australian Open. The 14th seed defeated the unseeded Jabeur 6-4, 6-4 and faces top seed Ashleigh Barty or Czech seventh seed Petra Kvitova in the last four in Melbourne. The Moscow-born 21-year-old, who defeated American 15-year-old Gauff in the previous round, said that she was "super-excited".

"It was a tough match," said Kenin, who moved to New York as a baby with her family with just a few hundred dollars to their name. Kenin said that holding her serve at 3-2 down in the second set in a game that stretched to 10 minutes was a turning point. "It was a tough moment, she was playing well. I didn't know it was 10 minutes but it felt pretty long," she said. "But after that I got my momentum and started playing better."
