Reigning champion Iga Swiatek withdraws from China Open

World No. 1 Iga Swiatek has pulled out of the China Open for personal reasons, the five-time Grand Slam champion said Friday.

She won last year’s China Open after beating Russian Liudmila Samsonova in straight sets in the final.

Swiatek, 23, withdrew from the Canadian Open and Korea Open, citing fatigue after winning the French Open title in June and a bronze medal at the Paris Olympics in August, before losing to American Jessica Pegula in the US Open quarterfinals.

“Due to personal matters, I’m forced to withdraw from the China Open in Beijing,” Swiatek said in a statement. “I’m very sorry as I had an amazing time playing and winning this tournament last year and was really looking forward to being back there. I know that the fans will experience great tennis there and I’m sorry I won’t be a part of it this time.”

The WTA 1000 event will run from Sept. 25 to Oct. 6.
