U.S. Open champion Emma Raducanu defeated Germany’s Tamara Korpatsch 6-0, 2-6, 6-1 at the Stuttgart Open on Thursday to set up a quarterfinal match against top-ranked Iga Swiatek.

It will be the 19-year-old Raducanu's first match against a top 10 opponent.

Raducanu, who won at Flushing Meadows as a 150th-ranked qualifier last year, could break into the top 10 herself if she wins the Stuttgart title in what is her first professional tournament on clay. She's currently ranked 12th.
