A no-ball is an illegal delivery in cricket that does not count as one of the required legal balls of the over and normally results in at least one penalty run being awarded to the batting side. The laws define numerous circumstances in which a delivery can be called a no-ball, including certain forms of illegal bowling action, foot placement, dangerous bowling, excessive bouncing or fielding and wicket related infringements.
The exact conditions vary with the laws and competition playing conditions. A no-ball is therefore not simply a delivery that misses the target or is difficult to hit. It is a technical classification indicating that the bowler has failed to deliver the ball according to one or more prescribed requirements. The umpire signals a no-ball using the recognised arm extended horizontally and the scoring consequences are then recorded in the innings.
One of the most common causes of a no-ball is an infringement of the bowler's delivery stride, particularly when the front foot lands beyond the permitted popping crease or outside the permitted return crease conditions. The bowler's feet must satisfy specific requirements at the moment relevant to delivery.
Modern professional cricket frequently uses technology to assist with close front foot no-ball decisions, particularly in televised matches, because a difference of only a small distance can determine whether the delivery is legal. Other potential causes include certain dangerous bouncers, deliveries above permitted height under applicable conditions, illegal fielding positions and various actions involving the wicket or batter. The governing laws contain detailed definitions, so the general concept should not be reduced to one type of infringement.
A no-ball normally adds one penalty run to the batting team's score, but the delivery can produce additional runs from the batter or through extras. If the batter hits the ball and runs are completed, those runs can be added in addition to the no-ball penalty. If the ball reaches the boundary after being struck by the bat, the resulting scoring treatment can include the no-ball penalty together with the applicable boundary runs.
This means a no-ball can produce a total greater than one run from a single delivery. The bowler is charged with the no-ball penalty and other applicable bowler-conceded runs, while byes or leg byes can have different implications for bowling figures. Accurate scoring therefore requires separating the penalty from the other runs produced by the delivery.
Because a no-ball is not a legal delivery, it does not count towards the six legal balls required to complete an over. The bowler must deliver another ball, which can itself be a no-ball or another illegal delivery. A sequence of repeated no-balls can therefore extend an over beyond the normal six physical deliveries. This has strategic consequences because the batting side receives an additional scoring opportunity and the bowler gives away penalty runs.
In many limited overs competitions, a no-ball can also lead to a free hit on the following delivery under the relevant playing conditions, although the exact free hit provisions depend on the competition. A free hit does not mean the batter cannot be dismissed in any way, but it restricts certain dismissal methods and can materially alter batting strategy.
No-balls can arise from the laws governing the bowler's actions as well as the behaviour of fielders. The bowler must comply with requirements concerning delivery stride, arm action and permitted forms of delivery. A delivery can also be called a no-ball because of dangerous bowling, such as certain excessively high full tosses or short pitched deliveries, depending on their height, speed and the applicable playing conditions.
Fielding restrictions and the placement of players can also interact with no-ball law in particular circumstances. The purpose of these provisions includes protecting players, preserving fairness and preventing bowlers from gaining an unfair advantage through prohibited techniques or positions. The no-ball is consequently both a scoring rule and an enforcement mechanism for the technical standards governing delivery.
No-balls are particularly significant tactically because they give the batting side an immediate scoring advantage while also providing an extra delivery. A bowler who repeatedly bowls no-balls can increase the opponent's score without creating a corresponding increase in the number of legal deliveries completed. In limited overs cricket, this is especially costly because the batting team receives additional opportunities within an innings that is otherwise constrained by a fixed number of legal deliveries. Bowlers therefore train extensively to maintain consistent run-up rhythm, front foot placement, release point and control. Captains and coaches monitor no-ball frequency because repeated infringements can affect both the numerical score and the psychological and tactical flow of an innings.
No-ball law must also be distinguished from wide law. A wide occurs when the ball passes sufficiently far from the striker to be outside the conditions for a ball from which the batter could reasonably hit it, subject to the applicable law and playing conditions, while a no-ball primarily concerns an illegal delivery or another specified infringement. A delivery can sometimes satisfy more than one conceptual concern, but the laws establish how it is to be called and scored. A no-ball also differs from a dead ball because a no-ball remains an active scoring event with prescribed consequences. Understanding these distinctions is important for scorers, players and spectators because the umpire's call determines both the score and whether another legal delivery is required.
The purpose of no-ball provisions extends beyond penalising mistakes. They help regulate the contest between bowler and batter by defining the physical and technical limits within which a delivery can be made. Some provisions protect batters from dangerous deliveries, while others ensure that bowlers do not gain an advantage by placing the front foot illegally or adopting prohibited actions. The laws have developed over the history of cricket as bowling methods, equipment, protective technology and tactical practices have changed. Modern officiating combines umpire judgement with technological assistance in some professional competitions. The no-ball is therefore a detailed component of cricket law that affects scoring, over length, dismissal possibilities, tactical planning, player safety and statistical records.
