Cameroon v Uganda: Bowler Mankads four batters
It's time to do away with this nonsense that it is unsporting to run out the non striking batsman when they are backing up. It's specifically allowed within the laws of cricket and it's not exactly sporting of the batsman to set off down the pitch before the ball has left the bowler's hand knowing that it's so unsporting to get him or her out that way and therefore won't happen.
I agree.
Firstly I don't like this notion that something is within the laws, but you shouldn't do it - if you shouldn't do it then change the laws.
But I'm also quite comfortable with the Mankad - effectively this is running out a batter who has chosen to take a risk decision to back up too far and is doing that to gain an advantage. So the response to that attempt to gain a (completely lawful) advantage is the risk of being run out by a Mankad. If you remove the risk of run out then there is nothing to stop the non striking batter backing up as far as they like to gain a great advantage.
So if you ban the Mankad you'd need to have some new and robust sanction to prevent a batter backing up outside their crease. Perhaps the equivalent of a bowler no ball - so one run removed if the non striker is outside their crease at the point of delivery. But that seems draconian and unnecessary - better to keep it as it is with the batter risking a Mankad run out if they back up too far, and indeed to encourage bowlers to consider this more as an option. That would force the non striking batter back into his or her crease.
