Absolutely spot on ! The other thing that nobody seems to have mentioned as far as i can see, is that what the keeper did should be against the rules and deemed as dangerous play. I know he only threw the ball underarm but if he had got that wrong and Bairstow had turned towards him he could have caught him in the eye and caused a serious injury to a player who was not watching. Having played a lot of amateur cricket over the years I have seen many an over enthusiastic keeper constantly flinging the ball at the stumps for no reason or annoyingly not being able to resist knocking the bails off " just in case ", etc, and it really gets on my nerves. The umpires should discipline keepers for doing that, it is totally against the spirit of the game and also wastes a lot of time. The keeper, Cummins and the umpires are culpable for what happened there and the cheating Roos should be ashamed of themselves, at very least Cummins should have called Bairstow back. Whilst in no way condoning any crowd misbehaviour, you can see what this kind of blatant cheating can lead to, in this case things could have got very ugly, thanks to the behaviour of these cheats ! The umpire had started to reach in his pocket for a cap or something for the bowler, surely that is a signal for end of over too !?
