LAHORE - Pakistan's tennis ace Aisam-ul-Haq Qureshi had another notch in his already outstanding career when he beat the second-best Australian tennis player after Leyton Hewitt - left handed 6' 7" giant Chris Guccione in straight sets at the Shimadzu Japan Indoor World Tennis Championship in Kyoto Japan. Aisam is now all set to meet the Croatian Ivan Dodig in the second round. Playing on the fast indoor carpet courts of Kyoto City Gymnasium, Aisam outplayed Guccione, ranked in the top 60 in the world and is currently considered the biggest server on the ATP circuit. With 45 aces in a match in last year's Australian Open, his reputation is well-earned for he was the ATP season 2008's highest ace server as well. Only recently Guccione had a big hand in Australia's recent Davis Cup victory against Thailand. With wins against such formidable players as world No 1 Rafael Nadal, Richard Gasquet, Hewitt, Juan Carlos Ferrero, Beydych, Igor Andreev, George Bastl, Max Mirnyi and Arnaud Clement already against his name, Guccione was served the surprise of his life when Aisam beat him. This was also the latter's first win against a top Australian Davis Cupper. So it indeed was tantamount to netting a big fish for Aisam, who outplayed the Australian in an impressive manner in straight sets by 7-6 (2), 6-4 - the encounter lasting an hour and 40 minutes. Aisam's strategy was rather simple. "I knew that Chris was a big server and returning him would not be easy. My main focus was to keep on holding my serve and wait for an opening. The moment I got an opening in the tie break, I scored and there was no looking back. Also in the tenth game of the second set I was able to raise my game to a very high level, and that yielded big dividend because I broke him to take the second set", a jubilant Aisam is reported to have said in his post-match comments. "Coming as it did against such an illustrious world class player, this without a doubt is one of my biggest wins ever", said Aisam. Fresh from his Davis Cup victories against Thailand, to begin with the big serving Guccione was all fired up. Aisam wasn't able to negotiate his serve for more than once or twice in every game. But his primary focus was holding on to his own service games, and this he did quite effectively to frustrate to the Aussie. When it came to tie break, Aisam hit some sparkling service return winners to take a lead and went on to win the tie break with a 7-6 (7/2) score. In the second set, the intensity as Aisam was 0-40 down in his second service game but served and volleyed his way out with aplomb. At 4-5 on Guccione's serve, Aisam displayed unbelievable quality tennis - hitting a down-the-line winner on the Aussie's first serve, following it up with a cross court winner to take 0-30 lead. Guccione hit an ace on the next point to make it 15-30, but then missed the first serve and Aisam brought the ball to play on his second serve to make it 15-40 after an interesting rally. At 15-40, Aisam hit a sizzling down the line return winner on the third seed's bullet-like first serve to clinch the issue.
