Top seed Garbine Muguruza pulled out of the Prudential Hong Kong Open on Sunday night - just hours after winning the China Open in Beijing.
The Spaniard said she had an ankle problem as she became the latest player to withdraw at the end of a gruelling season. Eugenie Bouchard, defending champion Sabine Lisicki and Victoria Azarenka were also casualties.
Muguruza, who turned 22 last week, retired from the Wuhan Open final against Venus Williams just a week ago, citing exhaustion.
By winning in Beijing, she sealed her spot at the year-ending WTA Finals in Singapore.
Garbine Muguruza can't believe she won the China Open. But organisers were even more disbelieving that she pulled out of the Prudential Hong Kong Open. Photo: Reuters
