Sydney:Martina Hingis' dream run has ended in the semi finals of her comeback tournament, losing 6-1, 6-7, 2-6 to world no 23 Flavia Pannetta of Italy at the Australian Hardcourt Championships. Hingis began strongly smashing forehand winners and displaying the class that helped her win five Grand Slam titles as she went on to take the first set 6-1. But by the second set, Hingis had started fading, something she later attributed to a hip strain sustained half way through the match. Hingis lost the second set in a tiebreaker after failing to close out the match at 6-5. After that it was just a matter of time as Pannetta gained momentum winning the third set 6-2 and setting up a clash in the final against Lucie Safarova. "I've played a lot of tennis, I've played some doubles too and just... you know, my body's not that used to it as it was when I was eighteen. You know, playing every week, singles and doubles. "The girls have got more physical, the game is faster. I'm just very proud that I've made it that far and I can build on that," said Hingis. Hingis is now looking forward to a few days away from the court before continuing her comeback in next week's Medibank International in Sydney.
