Cook's skittish cameo evidence the England skipper must get back into form with bat.
This has been an odd series for Alastair Cook. The satisfaction of retaining the urn in his first Ashes encounter as England captain will have been tempered by concerns about his own contribution.
Sure, his bucket-like hands have been in full working order in the slip cordon. True, he is ahead of his counterpart Michael Clarke in the use of the Decision Review System (and how he needed to be when the unerring eye of technology helpfully negated the doddery incompetence of the on-field umpires).
But Cook is a man who defines himself by his batting. And so far in this series, his batting has been well short of the dazzling peak it attained in his early days as captain.
On day three of this fourth Ashes test, what we saw was a fine batsman struggling to make sense of his dip in form. In the first innings in Durham, he had been scratching and scrabbling around without point or purpose. When Geoffrey Boycott criticises you for being unnecessarily pedestrian, then you know you have a problem.
