Henin and Sharapova face off

Justine Henin and Maria Sharapova will meet in the quarter-finals of the Australian Open after both enjoyed convincing wins in the fourth round.

Henin saw off Taiwanese qualifier Hsieh Su-Wei 6-2 6-2 while Sharapova was ruthless in her 6-2 6-0 demolition of 11th seed Elena Dementieva.

They will now meet in the quarter-final of a grand slam for just the second time when they clash on Tuesday.

Henin and Sharapova have met on eight occasions, with Henin winning six of those matches.

The most recent meeting was when Henin beat the Russian in three sets in the final of last year's WTA Tour Championship in Madrid in an epic clash.

Also through to the final eight is defending champion Serena Williams, who knocked out 12th seed Nicole Vaidisova 6-3 6-4 to set up a clash with Jelena Jankovic after the Serbian beat local hope Casey Dellacqua.

Third seed Jankovic put aside her shaky start to the tournament by dominating play, especially in the second set, against the unseeded and tournament surprise package Dellacqua.

Earlier in the day, four players completed the draw for the fourth round after their matches were delayed by wet weather on Saturday.

World number 146, Marta Domachowska, defeated 24th seed Li Na 2-6 6-2 6-4, while ninth seed Daniel Hantuchova eased past Virginia Ruano Pascual 6-2 6-3.

Russia's Nadia Petrova edged compatriot Ekaterina Makarova 6-1 7-6 (10/8), and Danish teenager Caroline Wozniacki accounted for another youngster, Germany's Sabine Lisicki 4-6 6-4 6-3.
