Defending champion Kim Clijsters defeated Caroline Wozniacki in the Australian Open quarterfinal 6-3, 7-6 (4) and with this loss, Wozniacki will have to give up her no.1 ranking.
She will next play the third-seeded Victoria Azarenka, who overcame Agnieszka Radwanska with a 6-7 (0), 6-0, 6-2 scoreline.
Wozniacki finished last year’s season at the top of the rankings, despite never having won a Grand Slam.
Clisters got off to a solid start and played the game that won her last year’s Australian Open. After taking the first set, she rallied to
a 5-2 lead in the second set and the match seemed to be over.
But Wozniacki wasn’t going to give up so easily and took the set to a tiebreak, in which the Belgian regained her focus again and won the set and the match.
In the other quarterfinal matches Petra Kvitova will meet Sara Errani and Maria Sharapova will play against Ekaterina Makarova.
