He picked up two quick boundaries, both off Kallis, but then attempted something a bit too inventive off the same bowler - trying to play a ball outside off-stump through the on-side.
But it was the briefest of honeymoons for Cook, lasting only until the last ball of the eighth over, when he played a half-hearted force off the back foot to a ball well wide of off-stump - and to the delight of the bowler Hilfenhaus, Michael Hussey dived expertly in the gully to take a fine one-handed catch.
