US Open champion Emma Raducanu's breakthrough season has ended with defeat in her opening match at the Upper Austria Ladies event.
Raducanu, set to announce Torben Beltz as her new coach, lost 6-1 6-7 (0-7) 7-5 to China's Wang Xinyu in Linz.
Wang, 20, played at a higher level than her 106th world ranking as 18-year-old Raducanu, the top seed in the event, suffered a second straight defeat.
However, the Briton was hampered by an injury near the end of a tight decider.
Raducanu, who climbed into the world's top 20 this week, struggled to cope with Wang's power and precision in a one-sided first set before settling down to turn the match into a contest.
