Third seed Daniil Medvedev on Wednesday reached the US Open semis, marching towards a first Grand Slam title. He won from his childhood friend Andrey Rubley with a clinical 7-6(6), 6-3, 7-6(5).
No player in the Open Era has won the U.S. Open men’s title without dropping a set.
Medvedev will face second seed Dominic Thiem in the semis.
Thiem put in a sublime performance and won from Australia Alex de Minaur 6-1, 6-2, 6-4.
The 27-year-old Thiem is the highest seed surviving at Flushing Meadows.
In the women’s section, Victorial Azarenka overpowered Elise Mertens 6-1, 6-0 Wednesday.
Azarenka will face Serena Williams in the semi-finals.
Serena, seeded third, came from a set down to overcome unseeded Bulgarian Tsvetana Pironkova and keep alive her bid for a 24th singles Grand Slam title at Flushing Meadows.
Her comeback included two astonishing shots with her left hand that contributed to winning points.
“At that point I was fighting so hard. I was just trying to do everything I can whether righty or lefty,” she said.
