Was having a conversation with a few mates a month or so ago, discussing pretty much what happened last night with Pietersen's catch - in fact, it might have been when Cameron White threw that ball back into play vs NZ. Now, AFAIK, the rule concerning a catch is that all you need to do is complete the catch. Pietersen had control of how he disposed of the ball, had control of the ball in his hand. IMO, it should be adjudged a catch.
Do the rules specifically state otherwise? Your opinions?
