Briton went down 6-3, 4-6, 1-6 to Zhu Lin
Raducanu called for trainer twice for treatment
Emma Raducanu again struggled physically in a first-round exit at the Ningbo Open to China’s Zhu Lin, raising questions over the rest of her season.
The British No1 was back on court a week after retiring from her opening match in Wuhan with dizziness in hot and humid conditions. She posted a picture on social media from a doctor’s office and said she felt better but she faded after winning the opening set against Zhu and slumped to a 3-6, 6-4, 6-1 defeat.
Initially, there did not appear to be any concerns, with temperatures lower than last week, but Raducanu began to look lethargic early in the second set and called the doctor after seven games.
