The main aim of off spin bowling is to deceive the batsman,
both in the air (by making the ball drift and drop quicker than would
normally be the case) and off the wicket (by making the ball turn
and bounce higher than would normally be expected).
This is largely achieved by making the ball:
| • |
spin very quickly (ie high level of revolutions
per minute) |
| • |
have the axis of rotation horizontal |
| • |
have a uniform direction of spin along the seam of the ball |
| • |
have a combination of ‘overspin’ and ‘sidespin’.
Depending on wind conditions and wicket conditions, a good rule-of-thumb
is to have an angle of spin, relative to its direction of travel
of 45°. |
How The Aggot™ works:
When bowling the The Aggot™, if spin is imparted on the ball
correctly, due to its physical shape, it will retain its disc shape
throughout its path in the air. Additionally, it will be clearly visible
what its angle of trajectory, rotation, direction of spin and axis
of rotation is.
The
Grip:
The grip used on The Aggot™ should be exactly the same used
for a normal ball.
The orthodox grip for the off spinner is a two finger grip, with the
first joints of the index and middle fingers spread widely on the
seam. Ideally the thumb should not apply any pressure onto the ball.
Spin is imparted primarily through the index finger.
The Ideal Off Break:
The “perfect” off break could be considered to have the
following properties in the air:
| • |
Very fast spin or revolutions on the ball. |
| • |
A uniform direction of spin around the seam of the ball. |
| • |
A combination of overspin (topspin) and sidespin so that not
only does the ball turn when it bounces off the wicket, but
it also drops in the air and bounces higher than would normally
be expected. A simple rule-of-thumb would be having the direction
of the spin at 45° (pointing to backward-square) as it travels
down the wicket. |
| • |
A vertical position as it travels down the wicket. This means
that the axis of rotation of the ball is horizontal resulting
in the fastest spinning part of the ball (which is around the
seam) hits the pitch first. |
Please note, different wicket conditions, state of condition of the
ball, wind strength and direction may affect the “perfect”
off- break at a particular time. |
