KARACHI (Agencies) - Former Pakistan Test captain Javed Miandad urged the banned trio of Salman Butt, Asif and Aamir to expose the people involved in illegal betting and corruption in international cricket. Pakistan cricket great Javed Miandad believes spot-fixing is more damaging to the game than match-fixing and urged the recently banned players to assist in purging it from the game. Miandad, who is the director-general cricket in the Pakistan Cricket Board (PCB), said he felt saddened by the damage the spot-fixing scandal had done to the image of Pakistan cricket. "I am hurt by the damage caused to our cricket and our image by the sanctions imposed on Salman, Asif and Aamir, but it is not possible they were working alone with Mazhar Majeed," Miandad said. "I am convinced that there is an entire mafia working behind spreading the menace of spot-fixing in our sport," Miandad, a veteran of 124 Tests, said. "I don't believe that only three players can do spot-fixing. I suspect that a lot of other people are involved in this racket," he added. Miandad urged the three players, who have faced sanctions from the International Cricket Council anti-corruption tribunal, to co-operate with the authorities in exposing the mafia. "These three should expose this mafia and help the PCB as because of them, Pakistan cricket has got a bad name." The former national coach said that he would soon meet with the PCB Chairman Ijaz Butt to discuss some proposals that would ensure such incidents didn't take place in future. Miandad also noted that in order to stop the spot-fixing menace, authorities needed to carry out a widespread operation in the cricket world and expose the players who are corrupt. Butt was last week banned for 10 years by the anti-corruption tribunal on charges of spot-fixing, while pacer Asif was banned for seven years and Aamir for five years by the tribunal. Miandad had no doubt that the three players had let Pakistan cricket and the PCB down by not admitting their guilt early on when they were accused of spot-fixing by the 'News of the World' newspaper. "These players should have told the PCB the entire truth instead of continuing to insist they were innocent," he said. Miandad, a director general of the Pakistan Cricket Board, said the banned trio should now assist the ICC and the PCB to identify those people involved in rigging betting markets, and thereby harming the game. "If the players identify the bad elements in the game, only then we can fight with this spot-fixing menace," Miandad told. "It (spot-fixing) can't be finished if the players do not cooperate." The tribunal also directed the banned players to participate - under the auspices of the PCB - in a programme of anti-corruption education. "It's a good programme, but it's the responsibility of the players to be honest because they are the ones who are directly approached by bad guys," Miandad said. "I'm sure no one has the guts to buy a cricketer without the consent of the player himself." Miandad was part of Pakistan's WC winning squad in 1992 and holds the record of most test runs for Pakistan with 8 832 runs from 124 test matches. He said spot-fixing poses a greater threat to the integrity of the game than match fixing because it provides more opportunity to fix betting markets; there is only one win-loss result per match, but there are vast numbers of bets on events within games. "In a 50-overs-a-side game players could commit an intentional mistake not once but 600 times," Miandad said, referring to the six-ball over bowled in a one-day international. "In match-fixing it's a matter of win or lose, but in this spot-fixing players commit intentional mistakes one after the other." Miandad said it was difficult to predict about the future of the three players, but termed the tribunal's decision as a 'reasonable verdict'. "It could have been more severe, but it will send a strong message to players all over the world."
