Sydney:Justine Henin extended her winning streak to 27 matches and advanced to the final of the Sydney International with a 6-2, 2-6, 6-4 win over Serbia's Ana Ivanovic on Thursday.
Playing her second match of 2008 - she received a first-round bye in Sydney and a walkover win in the second - Henin got a tough workout from Ivanovic's powerful groundstrokes and strong serves.
Henin, going for her third Sydney title, has not lost a match since dropping her semifinal against Marion Bartoli at Wimbledon.
The former Australian, French and US Open champion will meet Number 2 seed Svetlana Kuznetsova in the final on Friday.
Kuznetsova, also a former US Open champion, beat Nicole Vaidisova of the Czech Republic 7-5, 7-6 (4) in the other semifinal Thursday, saving a set point on her serve in the ninth game of the second set.
The Russian player then came back from 3-0 down in the tiebreaker to win seven of the next eight points and the match.
Henin saved three break points in her first service game, but played strongly for the remainder of the first set, breaking Ivanovic in the third and seventh games.
The pair traded breaks in the first two games of the second set before Ivanovic broke in the sixth game and again in the eighth, when she needed only one set point to close out the set.
The 25-year-old Henin broke in the third game of the final set, and converted on her first match point when the Serb netted.
''In the third set I just worked on my attitude,'' Henin said. ''Be positive and play point after point and be a little more aggressive.''
Henin is unbeaten in four matches against Ivanovic.
In men's quarterfinals, Australian Chris Guccione upset Number 4 seed Tomas Berdych of the Czech Republic 3-6, 7-6 (6), 6-4 and Radek Stepanek of the Czech Republic defeated Argentina's Agustin Calleri 6-2, 6-4.
Dmitry Tursunov of Russia defeated Sebastien Grosjean 6-4, 6-2 and France's Fabrice Santoro beat Russian Evgeny Korolev 6-3, 6-3.
