That batsman is timed out. They are dismissed for a duck after zero balls.
it is the striking batsman who ran
If the neither the batsman or the bat are touching the ground in the crease when the ball hits the wickets, the batsman is out. This is why it is important to 'grind your bat' as you run in.
While the batsman's position may affect whether an lbw call is made - if he is far out of crease and struck mid-thigh, for example, he would certainly not be given out, but in the shin when in his crease, he probably should - it is not a requirement that he be in, on or near his crease.
Undoubtedly the New batsman will be on strike.
the pitch is of 22 yards
A batter (or batsman) is not timed, as far as I know, in test cricket. It may be different in some of the other versions. If the batsman hits the ball without it being caught or running to score a run he will not be the batsman at the end of the over (six balls). His colleague will be the batsman for an over and then it will be his turn again.
he will be out if he leg and bat is up in the air!!
The popping crease is called so because it is the line that a batsman must reach to be considered safe from being run out. When a batsman "pops" their bat or foot over this line, they are deemed to be in their ground, thus avoiding dismissal. The term reflects the action of ensuring safety by reaching that crease, with "pop" suggesting a quick movement to secure one's position.
Cricket is an example of one sport where a batsman can be run out. This usually occurs when the wickets (or bails) are struck by the ball when the batsman is out of their crease.
22 yards
I think he asks the umpire or the batsman at the non-striker end that how many bowls have been bowled in the over.
From bowler to the strikers end is 20 yards 2 feet. The distance between the stumps is 22 yards. The bowling crease in aligned with the stumps. The batting crease for the off strike batsman is 4 feet in front of the bowling crease.
