Co-favorite Coco Gauff confidently reached the third round at the US Open. After the hard-fought opening victory over Laura Siegemund, the 19-year-old American won the duel of the young tennis stars with Mirra Andrejewa 6: 3, 6: 2.

The world number six had already defeated the Russian, who was three years younger, in the third round of the French Open this season and had more problems in three sets.

“I learned from being more aggressive. She has a great future ahead of her,” said Gauff on the pitch at Arthur Ashe Stadium. At the Grand Slam tournament in New York, she reached the quarterfinals as her best result so far.
