Melbourne, Australia ? Unseeded Marcos Baghdatis extended his remarkable run at the Australian Open, rallying Thursday to beat No. 4 David Nalbandian, 3-6, 5-7, 6-3, 6-4, 6-4, and reach the final.

With the crowd screaming support, the 54th-ranked Baghdatis guaranteed that he would more than double his career winnings. He will play the winner of today’s semifinal between top-seeded Roger Federer and No. 21 Nicolas Kiefer.

On the women’s side, second-seeded Kim Clijsters had to quit during her semifinal against No. 3 Amelie Mauresmo after injuring her right ankle. Mauresmo, seeking her first Grand Slam title, will face eighth-seeded Justine Henin-Hardenne on Saturday. Clijsters will be sidelined at least two months after tearing a ligament.
