However, Clijsters struggled to close the game as Wozniacki broke her serve then held her own to make it 5-5. The set eventually went to a tie break, which Clijsters eventually won 4-7. The Belgian took the set 6-7 to win the match.
Clijsters now heads into the semi-final against Victoria Azarenka.
