David Warner: Cricket Australia investigates 'abusive' Twitter posts By Andrew Hawes BBC World Service Sport Australia's Test opening batsman David Warner has been asked to explain why abusive messages to journalists have been posted on his Twitter account. Cricket Australia (CA) is examining the posts , some of which contain obscene language, which were written after News Limited's Robert Craddock criticised the Indian Premier League. Warner, 26, is likely to appear in the Ashes after his Delhi Daredevils stint. He has made 19 Test Appearances. Averages 39.46 with the bat. He has made three tons and seven fifties. In ODIs, Warner averages 30.37 from 37 innings with a strike rate of 81.15. In 44 innings in Twenty20 Internationals he averages 28.71 at a strike rate of 139.26 CA said it would comment fully after "conducting a thorough investigation." The other reporter mentioned in the tweets, Malcolm Conn, said he had spoken to the governing body. Conn said Cricket Australia, which was trying to contact Warner in Delhi, had told him it was "disappointed by the language" used on the social media website. The journalist added: "I'm all for free speech and strong opinions. I'd be quite happy to let it go. I don't think there's anything untoward about expressing your opinions but I can understand [Cricket Australia's] position. They are very concerned about their image. Twitter is followed by a lot of young people. It's a very bad look if you've got an international cricketer, particularly one with leadership aspirations, using bad language on social media when he's got 189,000 followers. Warner was recently named in Australia's squad for the Ashes Test series, which begins at Trent Bridge on 10 July. Averaging 39.46 with the bat, he has scored three centuries in 19 Tests. Australia also turn to Warner as an occasional bowler - among the leg spinner's four Test victims are South Africa's Hashim Amla and West Indies' Darren Bravo.
