Top-ranked Iga Swiatek cruised to a 6-0, 6-3 victory over sixth-seeded Coco Gauff in the quarter-final round at the WTA 500 San Diego Open.

Gauff had a double fault on the opening point and the outcome was seemingly never in doubt as Swiatek took control with her relentless, sharp-angled offensive attack in a rematch of this year’s French Open singles final, won by the 21-year-old from Poland, 6-1, 6-3.
