A seam bowler is a type of fast bowler in the sport of cricket who focuses on exploiting the seam of the cricket ball to achieve movement through the air or off the pitch. By delivering the ball with the seam positioned upright, seam bowlers can create unpredictable bounce and lateral movement, making it challenging for batsmen to play their shots effectively. Seam bowling is particularly effective on pitches that offer assistance, such as those with grass or moisture. Successful seam bowlers, like James Anderson or Glenn McGrath, often rely on precision and control to maximize the ball's seam movement, leading to wickets and pressure on the batting side.
