Defending champion Naomi Osaka falls to Belinda Bencic at the US Open

NEW YORK: Headline Naomi Osaka from Japan bothered 7-5, 6-4 by Belinda Bencic in the fourth round at the US Open on Monday when the Swiss reached the quarterfinals for the second time.

Bencic, seeded 13th, broke the world number one in the first game of the game under the closed roof of Arthur Ashe Stadium and his superior service passed the day, as he won 82% of his first service points on a rainy day in New York.

Momentum turned firmly in the direction of Bencic, 22, in the second set when Osaka failed twice to give the Swiss a 3-2 lead and the best-seeded Japanese, who seemed to fight with a problematic left knee, could not recover .

The victory meant that Bencic improved to 3-0 this year against Osaka, 21, who achieved an emotional victory in straight sets over 15-year-old Coco Gauff in the third round.

Bencic, who also reached the quarterfinals in 2014, but has had problems with injuries in recent years, said taking Osaka's powerful service early was key to his victory.

I was so excited to come to the court, that the challenge could not be greater, so I had to be at the top of my game, she said in an interview on the court.

I am really satisfied with how I played and how I handled my nerves in the end, she added.

I am not the person with the most winners or aces, I had to play a bit like chess with tactics on the court.

The next step for Bencic is a meeting with Donna Vekic, who came from behind to beat Julia Gorges with a 6-7 (5), 7-5, 6-3 victory on the Louis Armstrong Stadium court.
