MELBOURNE - Australia paceman Pat Cummins has backed opening batsman David Warner to carry his blistering Test form into the one-day arena at the cricket World Cup. Warner blasted three centuries in Australia's recent 2-0 Test series win over India, but he managed just the one half-century from five innings against South Africa in the preceding one-day international series. The pugnacious left-hander has a modest average of 31.40 from his 50 matches in 50-overs cricket, a far cry from his test average of 48.20.–Reuters
