The Oval is a good name for a ground synonymous with out of shape balls. Bob Willis is on England's case:

“Let’s not beat about the bush — Aleem Dar is on England’s case. He knows that one individual is scratching the ball for England — who I am not going to name — and that’s why the ball was changed.”

Well, yes, I have.
