New Delhi: England have toppled four-time former world champion Australia to take the number-one position in the Reliance ICC ODI Championship. Australia have lost its numero uno position for the first time since September 2009 while this is the first time England have topped the ODI Championship table.Australia have slumped to fourth spot which is its lowest ranking since the ODI table was launched in 2002 as its exceptional record of 30 wins and eight defeats from 40 ODIs in 2009-10 is no longer considered after the update. South Africa are second trailing just by one-sixth of a rating point, while world champion India are at third place â just one ratings point behind England.
