TV REPLAY Asking the third umpire when it's too close to call

This is a fairly recent innovation - the third umpire is called upon to look at television replays by a field umpire signalling a square mime of a TV screen.

Run outs, stumpings, doubtful catches and boundary issues can all be passed on and this has been a great help with crucial decisions.

I was always a bit suspicious of TV entering our game in this way, but I've been more than pleased with how it has gone.

We have a very difficult job to do and our duty is to try and get everything correct.

We are not able to refer things like lbw decisions - not yet anyway.

As the technology improves, I can see the third umpire being called in more and more.

Whether all of that will be good for the game, I'm not quite so sure because it will slow everything down.
