BRISBANE: Belgian comeback queens Kim Clijsters and Justine Henin followed the script to the letter on Friday to reach the final of the Brisbane International tennis tournament. Henin demolished third seed Ana Ivanovic 6-3, 6-2 to win the first semi-final while Clijsters was made to work much harder before overcoming unheralded German Andrea Petkovic 6-4, 6-2. Henin, granted a wildcard to play this week, was ruthless as she disposed of Ivanovic in just 65 minutes. There were no signs of any of the rustiness she displayed in her epic three-set win over Melinda Czink in Thursday's quarter-finals as she broke Ivanovic three times in either set. And while Ivanovic, like Henin a former World No 1, was able to break the Belgian's serve in each set, Henin came back even harder to break back almost immediately and underline her complete dominance. Clijsters looked on course for a similarly easy ride when she broke Petkovic in the opening game of the match. But the German refused to buckle to her more illustrious opponent and broke back later in the set to get the match back on even terms. However, the greater experience of Clijsters began to tell and she gradually wore her opponent down, taking the match in one hour and 20 minutes. Henin and Clijsters have set the tennis world alight since their respective comebacks. Clijsters, who retired in May 2007 and had a baby girl, set the ball rolling when she came back midway through last year to sensationally win the US Open. Soon after that triumph, Henin announced she too would end her retirement at the start of this year, with the Brisbane International marking her return to the court. In men’s section, top seed Andy Roddick gave a serving masterclass as he blasted his way past Frenchman Richard Gasquet 6-3, 7-6 (7/5) in the quarter-finals. Roddick will take on fourth seeded Czech Tomas Berdych for a place in Sunday's final, with the winner to face either Berdych's countryman Radek Stepanek or France's Gael Monfils. The American was on top form against a tricky opponent who has troubled him in the past and who beat him the last time they met, at Wimbledon in 2007. Berdych reached the final thanks to a hard-fought win over rising Brazilian star Thomaz Bellucci. The fourth seeded Berdych took two hours 42 minutes to see off Bellucci 7-6 (7/4) 2-6 7-6 (7/3).
