Henin still searching for next level 

World number one Justine Henin scrambled into the Australian Open fourth round with a tough 7-5 6-4 victory over Italy's Francesca Schiavone on Friday.

Henin, the 2004 champion at Melbourne Park, had problems with her serve in a match characterised by exploiting angles and opening up the court rather than power, but was able to break Schiavone when she needed to.

The 25-year-old Belgian had to battle back from two break points when serving for the match and secured victory when Schiavone's desperate return from a smash went wide.

The top seed next meets the winner of the third-round clash between France's Aravane Rezai and Taiwan's Hsieh Su-wei.
