The Polish top player Iga Swiatek made it through to the quarter-finals of the tennis tournament in Stuttgart.
The world number one prevailed in 86 minutes 6: 1, 6: 4 against the Chinese Qinwen Zheng. The next opponent of the 21-year-old is the Czech Karolína Plísková on Friday.
Swiatek is in first place at the high-class clay court event, which is endowed with around 715,000 euros. Last year she won the title in Stuttgart.
The American Coco Gauff, on the other hand, was eliminated in the round of 16. The sixth in the world rankings was surprisingly clearly defeated by the Russian Anastasia Potapova 2: 6, 3: 6.
