New revelations on match-fixing continue to rock English cricket with former captain Michael Vaughan now claiming that he knows a player who was approached by bookmakers. Vaughan, however, refused to divulge the player's identity and said matches cannot be fixed completely. I know of one (player who has been approached). I think within all this it's very important that these guys stay anonymous you hear of gangs and things that could happen, Vaughan was quoted as saying by 'The Independent'. Vaughan's comments come in the wake of ongoing investigations into alleged spot fixing in county matches. Essex duo Danish Kaneria and Mervyn Westfield were even arrested before being released on bail on suspicion of being in contact with bookmakers. Vaughan said some fixing is obviously there but to say matches are completely manipulated would be an overstatement. I don't know if it's rife in the game, I just know it's obviously going on. There have been rumours for many a year. I don't think it's happening all the time, he said. I don't think they're actually fixing the outcome of games, I think it's a little bit of spot-fixing. That, to me, is match-fixing because you're influencing the game in other ways, he added. Vaughan said it was good to see players coming out and reporting such matters to the England and Wales Cricket Board. I'm really pleased that guys are speaking out. You mustn't just point the finger at the players there are umpires that may get approaches, there are administrators who could get approaches, he said.
