The much anticipated Ashes warm up/preview/doesn't-mean-anything match starts in a little over one hour. Both sides say this has no bearing on the Ashes but we all know this just belies their nervousness at what may happen. Like it or not this is the psychological start to the Ashes. Flintoff is bravely coming in at number 3 again and what happens with his wicket will be big. Harmison did a bit of harm to himself last match and a mauling here could do irreparable damage so I'm sure the Aussies will go after him but the tactic could backfire badly if he does well. It will be a cagey cat and mouse game and there's no telling what will happen. A win for England will be huge. Conversely a mauling by Australia will be equally big. The pitch is unpredictable the dew factor is unknown. And the Diwali hydrogen bombs will be going off when the lights go down. Will we be seeing Mitchell Johnson, who had a gypy tummy yesterday or will that be an excuse to save him as a surprise for the main game in November.
