Australian coach John Dyson became the latest casualty of West Indies' bitter cricket turmoil Thursday when he was sacked as coach. The West Indies Cricket Board (WICB) axed Dyson following the humiliating home Test and one-day series defeats to whipping boys Bangladesh, losses which coincided with a damaging players boycott. Dyson's sacking comes less than six weeks before the start of the Champions Trophy in South Africa where assistant coach David Williams will take temporary charge. “The services of John Dyson have been terminated with immediate effect. The assistant coach David Williams will fill this position on a temporary basis for this tour,” said a WICB statement. Dyson, 55, took over as coach in Oct. 2007, following on from another Australian, Bennett King who stood down after World Cup. Before his appointment in the troubled Caribbean, Dyson had been coach of the Sri Lanka team, succeeding Dav Whatmore in 2003 and remained in the job for two years. He made an impressive start to his career with the West Indies, guiding the team to victory over South Africa at Port Elizabeth – its first overseas win in a Test for seven years. But success was always a struggle to achieve as more and more players fell out with the WICB over payments with the dispute becoming so entrenched that the first-choice squad refused to play in the series against Bangladesh. West Indies starts its campaign in the one-day tournament against Pakistan in Johannesburg on Sept. 23. Pomersbach banned Australian cricket authorities Friday banned Twenty20 star Luke Pomersbach from playing until at least January after he pleaded guilty to multiple charges including assaulting a police officer. The attacking middle-order batsman, who plays for Kings XI Punjab in the Indian Premier League, apologized in court for a drunken rampage that led to him being arrested by police in Perth Sunday. Pomersbach, 24, was fined 3,500 dollars (3,000 US) by the court, lost his driver's licence for six months and was ordered to pay more than 20,000 dollars (17,000 US) for the damages he caused.
