Why Angles Are Critical To Bowling And Batting Tactics

Ex-England captain Nasser Hussain once said that Duncan Fletcher taught him cricket was all about angles.

Don't worry; you can put down your protractor. Both men are right but you don't need to be a maths whizz to be able to use angles to your advantage.

So what do I mean when I talk about different angles?

Even the straightest of bowling without a hint of swing, seam or spin needs to consider certain angles.
If you were to bowl a ball on an imaginary pitch where there is a brick wall at the other end, you would never be able to get the ball to bounce straight back to you.

Because the stumps at the other end get in the way, the ball always bounces off at an angle.

This means that a ball that is of good line and length ends up in very different places depending on where it is released.

Let's look at some examples:

 Right-arm over: no movement

Right arm over: no movement

Left arm over: no movement
 
Left arm over: no movement:

The black line shows the line of the delivery, the dotted line shows the imaginary rebound.

As you can see, despite both ball being a good line and length, the angle the batsman is playing is completely different.

This angle can become even greater if the bowler goes wider on the crease or can be lessened by the bowler getting closer to the stumps.

What difference does this make to you?

Batsmen tend to play straight to a good line and length.

But now we know 'straight' is actually an angle. So now we know where the ball is more likely to go. It's easier to play a right arm over bowler with the angle into the leg side, even when playing with a straight bat.

Using movement to change the angle

Up until now we have assumed the ball has not moved in the air or off the pitch. However, most bowlers will be trying to get the ball to do something (admittedly with various degrees of success).

Right arm over bowlers who swing it away are reducing the angle to make the ball have a straighter rebound.

The same is true for:

•    Right arm over away swing
•    Left arm over inswing

This bowling his hard to get away because once the ball has moved onto the straight it must be played straight. Trying to hit across the angle is like hitting across the line: It reduces the amount or room for error and requires a lot more skill to pull off.

Even the worlds greatest can't do it consistently.

The angle can be increased with movement too:

•    Left arm spin around
•    Leg spin over

Both these move the ball from off to leg to the right hander, increasing the angle making it harder to hit straight or on the leg side with the ball 'going with the spin' in an arc between wide mid off and backward point:

Why angles are critical

Although most technically correct batsmen will do this beware of the player who is happy to hit the spinner across the line.

To combat this successfully the bowler will need to rethink both his packed cover area and the line he is bowling.

Taking the opposite view, an off spinner bowling over the wicket will increase the angle to the leg side making the hitting arc more likely to be to the leg.

Variations

All these notes so far have been about the classic angles to right handed batsman. There are some other angles to be aware of:

•    Going around the wicket will change the angle. For example, a right arm around bowler becomes similar to left arm over (although not quite as the left arm bowler can naturally get closer to the stumps).
•    Everything is in mirror image to the left handed batsman. For example the right arm outswing bowler becomes the same as a left arm inswing bowler.

Theory into practice

OK so that's enough theory. How can you apply it to get you more runs or wickets?

Let's look at some examples.

A left arm over bowler is swinging the ball back in to the right handed batsman.

If he bowls a good length at the stumps the ball will be pitching on leg or middle and leg. This means the batsman is forced to play straight and hit only to mid on or mid off.

To score runs without risk means trying to play the ball square onto the on side. The bowler can then place the field to prevent this.

However, if the if the bowler strays too wide, bowling an off stump line, the batsman knows he has a free hit at the ball through the less protected cover region.

Another example is the leg spinner who bowls close to the stumps with an off stump line.

Most hits will be on the off side and slightly squarer. Hits across the line will go between midwicket and mid on. The batsman will have to wait for a genuine bad ball to get away.

So next time you are thinking about line and length, also take some time to consider the angles.

As a bowler and captain it will help you set a good field. As a batsman it will help you see what the bowler is trying to make you do.
