Yes, wrist movement, often referred to as a "wrist jerk," is allowed in cricket deliveries.
Here's a breakdown:
- Legality of Wrist Movement: Any movement of the wrist during a delivery is perfectly legal and a fundamental part of bowling, especially for seam bowlers. This movement allows them to manipulate the ball's seam position and generate swing and seam movement.
- The Illegal Action: The Chuck: The only action that constitutes an illegal delivery is the straightening of the elbow by more than 15 degrees during the bowling action. This is often referred to as "chucking" or "throwing."
In essence, bowlers are encouraged to use their wrists to impart spin, swing, and seam movement. It is a critical skill for any bowler.
