American teenager Coco Gauff stormed into the US Open semi-finals for the first time with a superb, dominant victory over Latvia's Jelena Ostapenko.
Gauff, 19, won 6-0 6-2 in 67 minutes to record her best run at the tournament.
The American dropped only five points in a 20-minute first-set demolition and then claimed a closer second set.
She will play 10th seed Karolina Muchova of the Czech Republic or Romania's Sorana Cirstea, the 30th seed, in the semi-finals on Thursday.
Gauff, aiming to win her first Grand Slam title after losing to Iga Swiatek in the 2022 French Open final, had seen three of her first four matches at this year's US Open go to a deciding set.
