What is the difference between in out and reverse swing?

Answered by Michael Wilson

In cricket, swing bowling is a technique used by bowlers to confuse and deceive the batsman. It involves making the ball deviate from its normal trajectory in the air, either towards or away from the batsman. There are three types of swing: in swing, out swing, and reverse swing. Let’s delve into the difference between these types of swing.

1. Out swing: Out swing is the conventional form of swing bowling. It is typically performed by a right-handed bowler against a right-handed batsman (the same principles apply for left-handed bowlers and batsmen as well). The bowler grips the ball in such a way that the shiny side of the ball faces the slips, while the rough side faces the batsman. As the ball is released, the bowler imparts a sidespin on it, causing it to move away from the batsman in the air. This movement is known as out swing.

2. In swing: In swing is the opposite of out swing. It is the delivery that moves the ball towards the batsman in the air. The bowler achieves in swing by reversing the grip on the ball. The shiny side now faces the batsman, while the rough side faces the slips. The bowler releases the ball with the same sidespin as in out swing, but this time the spin causes the ball to swing towards the batsman, rather than away from them.

3. Reverse swing: Reverse swing is a phenomenon that occurs when the ball has become old, worn, and rough. It usually happens after the ball has been in play for a significant period of time. Reverse swing is not dependent on the bowler’s grip or the shine on the ball, but rather on the condition of the ball itself. When the ball is reverse swinging, it moves in the opposite direction to what is expected based on conventional swing. For example, if a right-handed bowler bowls an out swinger, the ball will swing in towards the batsman instead of away from them. Similarly, an in swinger will move away from the batsman instead of towards them. Reverse swing can be difficult to control and requires skill from the bowler to master.

It is worth noting that reverse swing is more commonly observed in subcontinent conditions where the pitches are dry, abrasive, and conducive to ball wear. Additionally, it is easier to achieve reverse swing with a ball that has a pronounced seam, as the rough side of the ball can grip the pitch better, creating the necessary conditions for the ball to swing in the reverse direction.

The key difference between in swing, out swing, and reverse swing lies in the direction of movement of the ball in the air. Out swing moves away from the batsman, in swing moves towards the batsman, and reverse swing is the unexpected reversal of the ball’s movement due to the aging and roughening of the ball’s surface. Each type of swing requires different techniques and conditions to be successfully executed.
