It was a victory for Naomi Osaka in two straight sets, 6-3, 6-4, against the American Shelby Rogers.
The Japanese took advantage of a stable serve and took the first victory of their career against Rogers.
- Honestly, I felt that she had the upper hand because I had never beaten her before and it has settled in my head, says Osaka who last met Rogers in 2017.
- So yes, it's a bit like revenge, she continues.
New American awaits in semifinals
Osaka played again with taped thigh, something she says is a precaution.
Next up is the American Jennifer Brady, who earlier in the day defeated Julia Putintseva, Kazakhstan, in two straight sets - 6-3, 6-2.
- I think she is a really fantastic player, she has the variety that I wish I had, so I'm a little jealous, says Osaka about the next opponent.
- But yes, she is super nice and I think it will be a really tough match.
Osaka is chasing his second US Open title.
