Leander Paes and Lukas Dlouhy advanced to the semifinals of the doubles event of the ATP Brisbane International Tennis event after getting a walk over from the local pair of Ashley Fisher and Stephen Huss at Brisbane on Thursday. A knee injury to Fisher forced the home favourites to opt out of the quarter-final contest against the top seeded Indo-Czech pair.Paes and Dlouhy will now fight it out with Jurgen Melzer and Philipp Petzschner, who shocked third seeded Michale Llodra and Andy Ram in their last-eight pair match of the 372,500 US Dollars hard court event. The unseeded Austrian-German pair scored a 5-7, 6-2, 10-8 win over the French-Israeli combination.
