Batsmen must be ready in three minutes - or 90 seconds in Twenty20
This is something you rarely see in any sort of cricket match.
Because it is a not a good sporting gesture, it is very rare that batsmen are ever timed out.
But you need to know about the law that says when a wicket falls, the next batter must be at the crease to face the next ball within three minutes of the wicket falling.
Should this ever happen, no player on the fielding side is given the credit for the dismissal.
In Twenty20 cricket, to keep the game speeded up, the incoming batsman must be ready to take guard (or for his partner to receive the next ball) within 90 seconds of the previous wicket falling, or he shall be timed out.
There have only been a handful of instances of batsmen being "timed out" in the entire history of first-class cricket - one of which was Nottinghamshire seamer Andrew "AJ" Harris in 2003.
With Notts playing Durham UCCE in a first-class friendly match, Harris was struggling with a groin strain when he came out to bat as Notts' last man - and was halfway down the pavilion steps when he was given out.
It has never happened in an international match.
