Reigning champion Iga Swiatek maintained her bid to become the first woman to successfully defend the French Open title in 16 years by cruising into the third round on Thursday. 

The World No. 1 crushed American Claire Liu 6-4, 6-0 on Court Philippe Chatrier. Swiatek, who turned 22 on Wednesday, will face China’s Wang Xinyu on Saturday for a place in the second week.
