The Ashes. If the current score for England is 2 wins, 1 loss and a draw, with one match to play...?

England won the Ashes last time they were played for in England. This means for England to retain the Ashes they just need to draw the series, so by the series being 2-1 in favour of England with only one match to play, the best result possible for Australia is a 2-2 series which would mean a drawn series and hence England retaining the Ashes.
