Raducanu sets up intriguing Swiatek battle in Stuttgart

Emma Raducanu will take on Iga Swiatek in an intriguing quarter-final at the Porsche Tennis Grand Prix but Maria Sakkari and Karolina Pliskova were eliminated.

US Open champion Raducanu overcame Tamara Korpatsch 6-0 2-6 6-1 to set up a meeting with world number one Swiatek.

It will be the pair's first meeting on the WTA Tour and Raducanu's maiden encounter with a top-10 opponent.

The Briton, who is playing her first Tour-level clay-court event, won 90 per cent of points on her first serve in the opening set but that slipped to 56 per cent as she opened the door to a comeback in the second.

However, Raducanu rediscovered her composure in the decider and got over the line after an hour and 39 minutes.
