England snatched a dramatic final-ball victory to take a 4-0 lead over Australia in their one-day series.

The hosts needed seven runs off the last over and a single off the final ball to pass Australia's testing 225.

Shelley Nitschke hit 71 off 106 balls and Karen Rolton struck 52 as Australia recovered from a poor start.

Charlotte Edwards (65) and Lydia Greenway (50) then impressed for England while Laura Marsh and Holly Colvin held their nerve at the end.
