A swing bowler is a type of fast bowler in the sport of cricket who uses the seam and the condition of the ball to create movement in the air. This movement can deceive batsmen, making it difficult for them to predict the ball's trajectory. Swing bowling is typically categorized into two types: inswing, where the ball moves towards the batsman, and outswing, where it moves away. To be effective, a swing bowler must have a good grip on the ball and an understanding of how to position it. Factors such as humidity, temperature, and the condition of the ball's surface can influence the amount of swing achieved. Notable swing bowlers include Wasim Akram and James Anderson, who have mastered this skill throughout their careers.
