Australian cricketer David Warner has defended his speak English demand in a slanging match with Indian batsman Rohit Sharma but admitted he was mistaken over the incident that sparked it. Tempers flared during Australia's four wicket tri-series ODI win at the Melbourne Cricket Ground yesterday when Warner demanded Sharma speak English instead of his native Hindi. Warner was fined 50 per cent of his match fee over the incident by the ICC. The incident was sparked after India ran a contentious single off an overthrow the Australians believed came after Warner's return deflected off Sharma. Cricket etiquette dictates that batsmen do not run when a throw deflects off their body or bat.
