Old Ball Tactics: Reverse Swing, Spin, and the Worn Cricket Ball
As a cricket ball ages across 40-80 overs, its physical properties change significantly — and bowlers who understand these changes can exploit the old ball as effectively as the new one. This article covers what happens to a cricket ball as it ages, how different bowling types use the old ball, and the tactics teams use to maximise the old ball's remaining potential before the second new ball.
How a Cricket Ball Ages
A cricket ball's physical properties change across 80 overs in several measurable ways: the lacquer coating wears off the smooth quarter of the ball (traditionally kept shiny by fielders licking and polishing one side); the seam reduces in prominence (the stitching that creates the seam is gradually flattened by ball-on-bat and ball-on-pitch contact); the leather on the rough side becomes scuffed and abrasive; and the ball's overall weight decreases slightly (ball loses about 1-2 grams across an innings from wear). These physical changes affect the ball's aerodynamics: the conventional swing that a new ball produces (where the shiny side creates more air resistance, causing the ball to curve) reduces as the lacquer wears; but new aerodynamic possibilities open up through reverse swing (where the rough side's increased air resistance changes the swing direction entirely).
Reverse Swing with the Old Ball
Reverse swing — the ball moving in the opposite direction to conventional swing at the same arm angle — is the old ball's most potent bowling weapon. It requires: one side of the ball significantly more worn and rough than the other (40-50 overs of wear typically produces this asymmetry); the rough side facing toward the same side where the conventional outswinger's shiny side would face; and pace (reverse swing is most effective at 135+ km/h — slower bowlers can reverse swing but the movement is less dramatic). The bowling technique is essentially identical to conventional swing — the movement is generated by the asymmetric aerodynamics of the worn ball rather than by a different bowling action. Batsmen find reverse swing particularly difficult because their visual reading of the bowler's hand position (which normally predicts swing direction) is no longer reliable.
Spin Bowling with the Old Ball
An old ball (40-60 overs, before the second new ball) is generally preferred by spinners for two reasons: the rougher surface allows more grip on the spinning finger, generating more turn; and the slower pace of the old ball (slightly lighter and less firm than a new ball) makes the spinner's flight and dip more effective (the ball hangs in the air longer before arriving at the batsman). Subcontinental spinners who bowl with a 60-over-old ball on a turning pitch are operating in near-ideal conditions — the rough ball grips and turns from the scuffed pitch surface, creating combinations of bounce, turn, and dip that make the ball genuinely unplayable even for elite batsmen. This is why, in Tests on turning pitches, the fielding captain often delays the second new ball to give the spinner 5-10 additional overs with the worn ball.
Frequently asked questions
Why was saliva banned from ball maintenance in cricket?
Saliva was temporarily banned from ball maintenance during the COVID-19 pandemic (2020) as a health precaution — saliva transmits respiratory virus droplets, and applying saliva to a ball shared by multiple fielders was assessed as a transmission risk. The ICC subsequently reviewed whether the ban should become permanent. Arguments for keeping the ban: research suggested saliva made minimal difference to swing compared to sweat (both achieve shine maintenance); and the COVID reasons for the ban had passed. Arguments for keeping the ban: it levelled a playing field where some bowlers were more effective at using saliva for ball management than others. The ICC's post-pandemic review has been ongoing, with different decisions at different levels of cricket about whether saliva use is permitted.
What is ball tampering and why is it a serious offence?
Ball tampering is the deliberate artificial alteration of the ball's surface beyond what is allowed by the laws — scratching the ball with fingernails, using abrasive substances to artificially roughen it, or using polishing agents not naturally produced by the body. Ball tampering is a serious offence because it provides the bowling team with an unfair aerodynamic advantage that the opposing batting team cannot anticipate or prepare for. The most high-profile ball tampering incident: Australia's 2018 Cape Town affair, where Cameron Bancroft was filmed using a piece of sandpaper to roughen the ball, leading to bans for Bancroft, Steve Smith, and David Warner. The incident prompted widespread discussion about cricket's culture around ball management and competitive ethics.
How do teams keep the ball in optimal condition across 80 overs?
Ball maintenance is a team-wide responsibility: every fielder who handles the ball can contribute to keeping the smooth side shiny. Standard practice: the fielder who retrieves the ball from the boundary passes it to the primary ball-maintainer (often a specific fielder designated by the captain — sometimes a seam bowler who understands what condition they want); that fielder shines the smooth side on their clothing, applies a small amount of sweat if needed, and passes the ball to the bowler. The rough side is left alone — it develops its roughness naturally through pitch contact. Teams aim to maintain the maximum asymmetry possible: one side as shiny as possible, the other as rough as possible, to maximise aerodynamic swing potential throughout the ball's life.
