A cricket ball can swing both ways after being released by the bowler. If you're a right-handed bowler, once you've released the ball with the correct grip, the ball can move from left to right in the air before it lands on the pitch. If the batsman is also right-handed, then this type of delivery swings into the batsman. Referred to as the inswinger, it's one of the most feared and effective methods for dismissing a batsman in a cricket match.
Measure the total width of the three stumps, including the gaps between, to 22.86 cm wide before placing the set of wickets into the ground.
Measure out the length of the pitch from the base of the wickets. The pitch should measure 20.12 m or 22 yards.
Mark out a line in the grass 1.22 m inside the 20.12 m mark. This is the line your front foot must not overstep in order for you to practice bowling a legitimate inswing delivery.
Bowling the Inswinger
Place the ball into your bowling hand with your index and middle fingers over the seam on the cricket ball.
Use your ring finger and thumb to support the bottom of the ball. Place your thumb onto the seam and your ring finger next to it, supporting both the ball and your thumb. Your baby finger should tuck in underneath your ring finger.
Angle the seam, once the vertical seam grip has been mastered, toward the leg side of the batsman.
Using your wrist as a hinge, cock your hand backward to create some leverage for the inswinging delivery.
Start the run-up as you would for any normal bowling delivery. As you approach the line for your front foot that you marked out earlier, enter your normal bowling action until just before the moment you release the ball.
Using the leverage you've created with your cocked wrist, use a flicking motion to release the ball.
Release the ball toward the stumps by curving your wrist as you let go of the ball. Imagine just before the moment you bowl the ball that a pole has been placed directly in front of the ball. This will help you curve your wrist clockwise around the imaginary pole.
Allow your wrist to do as much of the curving as possible. Keeping the same arm action as normal restricts the batsman in predicting what delivery you're choosing to bowl.
