Emma Raducanu’s brutal run of form and luck in Asia continued at the Wuhan Open as she retired because of illness from her first-round match at the WTA 1000 event, while trailing 6-1, 4-1 against the American Ann Li.

Raducanu is the latest player to crumble in tough conditions across China, with temperatures rising to 31C with 67% humidity in Wuhan on Tuesday afternoon.

Raducanu looked out of sorts throughout the match before getting her blood pressure checked late in the second set and citing dizziness as she retired.
