Bowling Actions in Cricket: Right Arm Over, Round, and Different Release Points
A cricket bowling action describes the combination of run-up, side-on or front-on body position, arm angle, and release point that a bowler uses to deliver the ball. Different bowling actions create different angles of delivery, degrees of swing, and seam positions at release. Understanding bowling action types explains why a left-arm bowler is different from a right-arm bowler even at the same pace, and why certain batsmen struggle against specific action types.
Bowling action basics: a cricket bowling action has three main components: (1) the run-up — the bowler's approach to the crease, which builds pace and rhythm; (2) the delivery stride — the last two steps before release, where the bowler's body coils and their front arm pulls down while the bowling arm comes through; (3) the release — the moment the ball leaves the bowler's hand, determined by the angle of the arm, the position of the wrist, and the position of the seam. Legitimate bowling actions must involve a straight arm at the point of release — the elbow must not straighten by more than 15 degrees (the ICC's 'throwing' limit) between the point when the arm is horizontal and the point of release.
Over the Wicket vs Around the Wicket
Over the wicket vs around the wicket: every bowler has a natural side they bowl from relative to the stumps. For a right-arm bowler: over the wicket means the arm comes from the right side of the umpire (the standard position); around the wicket means the arm comes from the left side of the umpire (a less common position that creates a different angle). Switching from over to around changes the angle of delivery significantly — for a right-arm bowler going around the wicket to a right-handed batsman, the ball is angled from a wider position on the off side (outside off stump), making deliveries that cut back into the stumps particularly difficult to play. Left-arm orthodox spinners frequently bowl around the wicket to right-handers to target the footmarks (rough) outside the off stump — the ball turns from outside off stump toward the stumps.
Round Arm and High Arm
Arm height in the bowling action: the angle of the bowling arm at release (the arm slot) affects the trajectory and movement of the ball. High arm (arm close to vertical at release): creates more bounce, less angle variation, traditional Test bowling style; the ball comes over the top, meaning it attacks the off stump directly. Round arm (arm lower, more horizontal at release): creates a flatter trajectory, the ball skids on, and more variation in the angle from a seamer — the ball can naturally angle across the right-hander. Very high arm: sometimes called 'over the top' — creates extra bounce and is associated with bowlers who bowl from a high wrist position (rare but effective, like Shaun Pollock). The ICC has rules about the minimum acceptable arm height — bowlers who release the ball with their arm nearly horizontal are technically bowling a 'throw' variant that the Laws prohibit.
Illegal Actions and Throwing
Illegal bowling actions: a bowler's action is illegal if their elbow straightens by more than 15 degrees between the horizontal position and the point of release (the ICC's 2004 ruling on 'chucking'). Bowlers whose actions show this straightening are reported to the ICC and must undergo biomechanical testing at an approved centre. If found to exceed the 15-degree limit, they are suspended from bowling internationally until they modify their action. The most prominent case: Muttiah Muralitharan (Sri Lanka) was called for throwing by Australian umpire Darrell Hair in 1995-96; Murali's doosra delivery was later measured at 14-16 degrees of elbow straightening, right at the limit. The ICC's 15-degree rule (introduced in 2004) was partly designed to allow Murali to continue bowling without being called for throwing, based on biomechanical evidence that many bowlers' arms straighten within this range naturally.
Frequently asked questions
What is over the wicket bowling in cricket?
Over the wicket in cricket means the bowler delivers the ball with their bowling arm on the same side as the stumps — the standard delivery position for right-arm bowlers (arm comes from the right side of the umpire). For right-arm bowlers, over the wicket is the conventional position; for left-arm bowlers, it means the arm comes from the left side of the umpire. A bowler can also deliver around the wicket, where they cross to the other side of the stumps — the bowling arm then comes from the opposite side of the umpire. Switching from over to around the wicket changes the angle of delivery significantly, creating a different hitting line for the batsman and allowing the bowler to target different areas (e.g., footmarks in the rough outside the off stump).
What is a front-on bowling action in cricket?
A front-on bowling action is a delivery style where the bowler's chest and shoulders face more directly toward the batsman at the moment of delivery (as opposed to the side-on action, where the shoulders are perpendicular to the batsman). Front-on actions can naturally promote inswing because the body position opens the hip and allows the ball to be released with an angle that curves back into the right-handed batsman. Front-on bowlers include Wasim Akram and some modern inswing bowlers. The historically recommended action in coaching was side-on, but modern biomechanics coaching accepts both — the key is that the action must be consistent and not create stress injuries (mixed actions, where the body coils in contradictory directions, cause back injuries).
What is throwing in cricket bowling?
Throwing in cricket refers to an illegal bowling action where the bowler's elbow straightens by more than 15 degrees between when the arm reaches horizontal and the point of release. The ICC set the 15-degree limit in 2004 as the maximum allowable elbow straightening (since all bowling actions involve some natural elbow straightening). Straightening beyond 15 degrees is illegal because it provides an unfair mechanical advantage (similar to throwing rather than bowling) — allowing the bowler to generate pace and spin beyond what a truly straight-arm action would allow. A bowler suspected of throwing is reported to the ICC and must undergo testing at a biomechanical laboratory. If found to exceed the 15-degree limit, they are banned from bowling in international cricket until they modify their action to comply.
