Bowling (cricket)

In the sport of cricket, bowling is the primary method of propelling a ball toward a wicket. This action is performed by a player known as a bowler. The main objective of bowling is to dismiss the batting side by hitting the wickets. This removes batters from the crease and prevents them from scoring runs. A bowler who also possesses high skill as a batter is called an all-rounder.

A single delivery is often called a ball. Bowlers deliver the ball in sets of six, which is known as an over. Once an over is complete, a teammate bowls from the opposite end of the pitch.

Bowling is strictly distinguished from throwing through a specific biomechanical definition. The Laws of Cricket regulate how the arm must move during a delivery. Historically, rules stated the elbow joint could not straighten during the action. However, scientific studies in 2005 showed this was physically impossible for most players. The stress of the swing causes the elbow to hyperextend slightly. Because of this, a guideline now allows for extensions up to 15 degrees. If a bowler exceeds this limit, the umpire calls a no-ball.

Bowlers use various techniques to deceive the batter. Fast bowlers rely on high pace to challenge the opponent. Swing and seam bowlers aim to make the ball deviate in the air or off the pitch. Slow bowlers use flight and spin to trick the batter. A spin bowler delivers the ball slowly and imparts rotation. This causes the ball to turn at an angle when it bounces.

These different styles allow a team to adapt to different match situations. A captain must decide between attacking or defensive bowling strategies.

There are two main body positions for a bowling action: side on and front on. In a side on action, the back foot lands parallel to the bowling crease. The bowler looks over their front shoulder to aim at the wicket. In a front on action, the back foot points down the pitch. The bowler looks inside the line of their front arm to aim. Some players use a mid-way action with a 45-degree foot landing. However, experts discourage a mixed action because it can cause back problems.

The history of bowling is filled with many changes. Early theories suggest cricket began with shepherds using crooks to hit wool balls. Another theory links the name to a low stool called a 'cricket.' The first written Laws of Cricket appeared in 1744. These laws required stumps to be 22 inches high and six inches wide. The ball had to weigh between 5 and 6 ounces. The two sets of stumps were placed 22 yards apart.

In the 1770s, bowlers began pitching the ball through the air. This innovation led to the replacement of curved bats with straight ones.

Bowling methods have evolved significantly since the 18th century. Originally, underarm bowling was the only method used. In the early 1800s, players began experimenting with round-arm techniques. This was initially banned by the Marylebone Cricket Club (MCC) but was accepted in 1835. Underarm bowling nearly disappeared until a controversial incident in 1981. During that match, Trevor Chappell rolled the ball along the ground to prevent a six. This event led to underarm bowling being made illegal in almost all cricket.

As the game grew, equipment and rules became more standardized. The MCC was founded in 1787 to help manage the sport. Between 1770 and 1790, recorded matches rose to over 500. In 1841, players began using cork pads for protection. By 1848, they used rubber gloves to protect their hands. These developments helped players handle the increasing pace of modern bowling. Today, bowling remains a complex skill that combines physics, strategy, and physical discipline.
