(Reuters) - Defending champion Caroline Wozniacki and top seed Elina Svitolina, who have both qualified for the season-ending WTA Finals, withdrew from the Hong Kong Open through injury on Thursday.
Wozniacki pulled out before her match against Lizette Cabrera with elbow pain, giving the Australian teenager a free passage into the quarter-finals.
