Emma Raducanu ended her breakthrough season with a 1-6, 7-6(0), 5-7 defeat to World No 106 Wang Xinyu in the second round of WTA 250 event in Linz.
But it wasn’t without controversy.
The 18-year-old Brit, who emerged as the surprise winner of US Open, took a medical timeout just before her opponent served for the match at 5-4.
Wang, 20, got off to a blistering start and clinched the opener in just under half an hour as her deep returns forced the top seed into several errors.
Raducanu was unable to match her opponent, who won over 85% of points on her first serve.
The 18-year-old Briton responded well in the second set, breaking in the first game following a rare error from Wang before the Chinese qualifier hit back with a break of her own at 3-4.
Raducanu, however, outclassed Wang in the tie-breaker, striking a flurry of winners to win seven straight points and force a decider.
There were no break points in the decisive final set until Wang powered through a love break for 5-4.
Raducanu then called the trainer on court for a injury for what appeared to be an injury to her right leg.
Serving for the match, Wang squandered two match points as Raducanu pulled back level at 5-5, but the Chinese player quickly gritted out another break for 6-5.
Torben Beltz is the new coach
Raducanu has appointed German Torben Beltz as her new coach, she confirmed after the defeat.
“It’s obviously a great privilege to be working with such an experienced coach. I’m definitely very excited to work with him throughout the pre-season and into next year,” Raducanu, who had been the top seed in Linz.
“Very positive feeling about all the work there is to come.”
