Wozniacki digs deep

World number one Caroline Wozniacki hit back from a set down to finally break the resolve of Francesca Schiavone and move into the Australian Open semi-finals.

Schiavone, who needed four hours and 44 minutes to squeeze past Svetlana Kuznetsova in the longest women’s match in grand slam history in the previous round, fought valiantly but ran out of gas after a fine start to go down 3-6 6-3 6-3 .
