Coco Gauff reaches maiden US Open semifinal at age 19 by beating Jelena Ostapenko

Coco Gauff thrashed Jelena Ostapenko in straight sets to reach the semi-finals of the US Open for the first time on Tuesday. American sixth seed Gauff dominated Latvia's 20th seed Ostapenko from start to finish, winning 6-0, 6-2 in just 1hr 8min. Gauff, 19, will face either Czech 10th seed Karolina Muchova or Romania's Sorana Cirstea in the last four on Thursday.

Gauff, beaten in the quarter-finals last year, is the first American teenager to reach the US Open semi-finals since 2001. "It feels great, I'm so happy," said Gauff. "Last year I lost in the quarter-finals stage and wanted to do better this year. I have a long way to go but I'm happy and will be ready for the next one." "I didn't feel comfortable at all the whole match, even at match point.

She has the ability to come back no matter the scoreline so I was just trying to play every ball and hit it deep."
