Defending champ Naomi Osaka knocked out in fourth round of U.S. Open
Naomi Osaka was bounced 7-5, 6-4 by Belinda Bencic of Switzerland in the fourth round of the U.S. Open. The top-seeded Osaka won’t have a chance to defend her title after winning her two previous matches in straight sets.
Osaka had never beaten Bencic, including two losses to her earlier this year. Osaka’s left knee appeared to be bothering her slightly, but Bencic was the better player from start to finish.
