Defending champion Swiatek motors into Stuttgart quarterfinals

World No 1 and defending champion Iga Swiatek progressed to the quarterfinals of the WTA Stuttgart clay-court tournament by beating Elise Mertens in straight sets on Thursday, her ninth win in nine career matches at the French Open warm-up event.

Swiatek beat the unseeded Belgian 6-3, 6-4 to maintain her bid to capture a third successive title in the German city and be handed the keys to a third luxury car from the sponsors after also winning the tournament in 2022.

“There’s always space for a Porsche. If not, we’ll make it. I’ll build an underground garage,” said Swiatek after playing her first clay-court match since lifting the French Open title last June.
