'It's ridiculous. Why penalise my player and not the other guy?' Hong Kong coach Chan Kong-wah has launched a stinging attack at the officiating at the 48th World Championships after several controversial calls in the opening round match for his top men's singles player, Leung Chu-yan. Leung, seeded 20th, had kick-started his campaign at Shanghai Gymnasium with an easy 4-0 romp over Spain's Marc Duran but came unstuck in his second match last night, losing to Christophe Legout of France 4-3. The Frenchman prevailed in a titanic battle, 11-4, 8-11, 11-5, 8-11, 5-11, 11-6, 11-6. The outspoken Chan, who has made his feelings known about the level of officiating in the past, criticised the mainland umpire for penalising Leung a point for a service fault early in the match against Duran - an offence Chan said Leung was not guilty of. But Chan said the one-point penalty was not the reason why he was angry. He claimed that Duran, had not been penalised for any service faults even though Chan felt that Duran was guilty of committing '10 times as many service faults'. 'It's ridiculous,' said Chan. 'Leung Chu-yan might have been guilty of one service fault, but his opponent made at least 10 service faults and he got away scot-free. This is unfair. Why penalise my player and not the other guy? 'This might seem a trivial thing, but what happens if it occurs again in the later rounds, the quarter-finals, or the semi-finals? This are the World Championships and the eyes of the world are watching. 'Making these silly decisions could present a real problem if it happens again. I am not happy with the umpiring today,' Chan declared. Chan was understandably upset since Leung - a quarter-finalist at last year's Olympic Games - was his leading men's singles hope. 'I don't mind if my player gets penalised, but there should be some consistency. 'If my player gets penalised but the other player doesn't even though he clearly made at least 10 service faults, then something is wrong,' said Chan. The rules imply that players must not 'hide' the ball while serving or spin the ball while tossing it in the air before serving. The ball must be placed squarely in the palm of the hand and clearly visible to the opponent. Duran looked to have made at least five service faults, but was never warned or penalised in the match that Leung won in just 27 minutes. 'Leung Chu-yan's opponent was spinning the ball in the air. And he got away with it. Chu-yan didn't commit his offence deliberately. We never do this in training so why do that here? This is crazy,' said Chan. Hong Kong international umpire, Cindy Leung, defended the umpire's decision, saying players were not penalised unless umpires were '110 per cent' certain that they had committed an offence. 'Very often the players might use their fingers to spin the ball when they serve and this is the incorrect way to serve. It's very easy to make mistakes when serving. I don't think the umpire would have made an error in judgment,' she said. Meanwhile, Hong Kong's top women's singles hope, Tie Yana, coasted into the second round with a 4-1 victory over American Jacqueline Lee. Tie meets Italian Nicoletta Stefanova next. Hong Kong's Athens heroes, Li Ching and Ko Lai-chak also had few problems as they powered into the third round of the men's doubles. The SAR's leading gold medal hopes were in fine fettle as they first defeated the Norwegian pair of Geir Erlandsen and Wang Jianfeng 4-0 before dropping one set in defeating Hungary's Zoran Primorac and Tosic Roko 4-1.
