AUSTRALIAN Rodney Martin ended Jansher Khan's 28-match unbeaten run in the Hong Kong Open squash tournament with a comprehensive straight games semi-final triumph yesterday to set up a title clash against elder brother Brett. Rodney stormed to a 15-14, 15-7, 15-9 win in the transparent acrylic court at the Hong Kong Park Indoor Games Hall after Brett had earlier beat English hopeful Simon Parke 15-11, 15-11, 15-11. World number three Rodney took the early initiative and opened up an 11-8 lead in the first game but Jansher produced the winners to save three game points. Rodney called for a sudden death and won it with Jansher hitting the tin. Top-seeded Jansher, who lost his number one ranking to Australia's Chris Dittmar after he was penalised for late withdrawal from three tournaments, made a determined bid for a comeback in the second game. He engaged Rodney in long rallies but a couple of uncharacteristic errors while trailing 5-4 knocked the fight out of him and he could only win three more points. The five-time winner of the Hong Kong Open picked up the pace at the start of the third game and raced to a 9-4 lead, but he ran out of steam and Rodney swept the next 11 points to hand Jansher his first defeat in the territory. ''I was playing very badly for the past two or three months but I put in a lot of training and just hoped everything would come together at the start of the season,'' said Rodney, winner of the Australian Open last week. ''The hard training is paying off and I'm more focused on what I had to do and didn't let him get into a rhythm.'' Jansher admitted he lost to the better player on the day but felt he lost the match on the sudden-death point in the opening game, a rally he disputed after hitting the ball into the tin. ''I doubted his pick-up but the referee said it was okay. The first game was a very important one to win and if I had won it I would have won the match,'' Jansher said. ''But he was playing fantastic squash today, attacking from everywhere. It was just his day.'' Fourth-ranked Brett had an easy time against Parke, overwhelming the English 1990 junior world champion in 34 minutes. It will be only the second time the Martin brothers have faced each other in a Professional Squash Association-sanctioned final - they met in the 1991 US Open, which Rodney won. Meanwhile, Hong Kong's Andrew Shum Siu-chung will know this week his penalty for striking his opponent in the New Zealand Open early this month. Shum was disqualified for jamming the shaft of his racquet into New Zealander Cameron Barbour in frustration when the referee awarded a stroke against him. Roger Eadey, executive director of the PSA, said: ''We've received the official complaint from the referee and also the tournament director's report.''
