Suppose a bowler bowls a shoulder height ball at the batsman and the batsman hits a four or gets out. Can the ball be called as a bouncer?
The law/meaning of the bouncer is the ball bounces above shoulder height irrespective of a batsman hits it or not. So it is considered a bouncer even if a batsman hits it and gets runs or out.
As per ICC rules, Bouncer is declared when bowler bowls above batman's shoulder height.Because its pretty obvious that if ball is above shoulder height, Batman might be not able to play it.
So Everytime when bowler bowls above shoulder height, Leg umpier straight away declare it as NO BALL wheather batman hits it or not.
