If a delivery passes the batsman and fielder and a run is scored, it is known as a bye. It is a legal delivery passing the stumps with the ball touching neither the bat nor the batsman's body. The umpire's signal is one arm stretched above the body.

Called when a ball hits any part of the batsman's body (except the hand holding the bat) and not the bat. It is signalled with a hand touching the umpire's raised knee. Byes are important because any runs scored don’t count against the bowler.

This is signalled by an arm raised at shoulder height. The most common no ball is the foot over the popping crease. These can also be given for too many high bouncing balls or a full toss above the waist.

A delivery too wide for a batsman to play a shot. It is signalled with both arms outstretched.

When a ball is hit to the boundary the umpire signals a four. The boundary four is signalled by waving an arm from side to side, finishing with the arm across the chest. Each umpire has his own way of doing this.

When the ball is hit clean over the boundary the umpire will signal a six by raising both hands above his head.

The raised finger from the umpire is the signal all batsmen dread. As soon as that finger goes up, the batsman has to go. The raised finger from the umpire is the signal all batsmen dread. As soon as that finger goes up, the batsman has to go.

Here’s one you won’t see in junior cricket! Run-outs, stumpings, doubtful catches and boundary issues can all be passed on for a TV replay. The third umpire is called upon to look at TV replays by a field umpire. They cannot be called upon for lbw decisions.
