Wozniacki, Svitolina pull out of Hong Kong Open
The Hong Kong Open has been stripped of its remaining two stars after top seed Elina Svitolina and Caroline Wozniacki both pulled out.
Caroline Wozniacki andÂ Elina Svitolina have both pulled out of the Hong Kong Open, handing walkovers into the quarter-finals toÂ Lizette Cabrera and Nicole Gibbs respectively.
With Eugenie Bouchard,Â Agnieszka Radwanska and Venus Williams having already been eliminated from the tournament,Â Wozniacki and top seedÂ Svitolina were the remaining star names in the draw.
Svitolina withdrew with a groin injury sustained in a marathon defeat to Caroline Garcia at the China Open, while Wozniacki cited an elbow problem when she pulled out shortly before her match against Cabrera on Thursday.
"I want to apologise to everyone who came outÂ to watch this match," defending champion Wozniacki told the crowd on court.
"I did everything I could possibly to get ready. But unfortunately I hurt my elbow during practice and there's just no way I could perform my best out hereÂ and unfortunately I have to withdraw from the tournament."
Svitolina and Wozniacki are among the eight players to have qualified for theÂ 2017 WTA Finals, which will be held in Singapore later in the month.
Jennifer Brady set up an all-American quarter-final clash against Gibbs by upsettingÂ Zhang ShuaiÂ in straight sets, while China'sÂ Wang QiangÂ will faceÂ Samantha Stosur in the last eight after triumphing 6-4 6-4 againstÂ Luksika Kumkhum of Thailand.
Cabrera will playÂ Daria Gavrilova in Friday's quarter-finals, while sixth seedÂ Anastasia Pavlyuchenkova faces Williams' conquerorÂ Naomi Osaka.
