Swing bowling is a technique used in cricket where the bowler makes the ball move in the air as it travels towards the batsman. This movement can be either towards or away from the batsman, depending on how the bowler grips and releases the ball. The key to effective swing bowling is the condition of the ball; a shiny side and a rough side help create the necessary aerodynamic differences. There are two main types of swing: conventional swing and reverse swing. Conventional swing occurs when the ball is new and can swing at slower speeds, while reverse swing happens with an older ball, typically at higher speeds. Mastering swing bowling can make it challenging for batsmen to predict the ball's trajectory, increasing the chances of taking wickets.
