If bowled at velocities over 70 miles (110 km)-per-hour, the ball will swing toward the smooth side of the ball. If bowled below 70 miles (110 km)-per-hour, the ball will swing toward the rough side of the ball.
Cricket balls that are new may have very little difference between the smooth and rough sides. This makes them less prone to “swing” through the air when bowled.
Depending on your release, you may benefit from a different middle finger position. Experiment to see what your prefer.
To throw a leg cutter, place your middle finger on the seam and allow your index finger to rest on the right side of the ball. This slight variation in angle will cause the ball to hit the ground on the opposite side of the seam, forcing it to bounce the other direction (toward the “off side” of a right-handed batter).
You will generate more energy and velocity the better you can learn to shift your weight. If you shift too early it will affect the speed of your “run-up. "
Make sure you plant your lead foot so that it points toward the batter.
Shifting your weight properly will generate momentum.
Throws are illegal in cricket. If you bend your arm and lead with the elbow it will count as a throw. The shoulder must be the body part through which power is generated. Umpires will call a “no ball” when a player throws or “chucks. "
Snapping your wrist also prevents you from releasing the ball too late, which is often times the result of a player compensating for an improper angle of release. Overtime, a late release can result in excessive stress and/or injury to the bowling shoulder.
Because of its weight, a cricket ball can cause injury to the elbow if it is “thrown” or bowled incorrectly.
