Ball Tampering Laws in Cricket Explained
What constitutes ball tampering in cricket, what is legal vs illegal, and the penalties under the Laws and ICC code.
What Is Ball Tampering?
Ball tampering is the deliberate, illegal alteration of the condition of the cricket ball. Because the ball's surface condition directly determines whether it swings, seams, or reverse-swings, manipulating that condition gives the bowling side an unfair advantage. The Laws of Cricket and ICC Code of Conduct both address ball tampering explicitly, with significant penalties for those found guilty.
What Is Legal Ball Care?
- Polishing the ball with sweat or saliva (though saliva was restricted during COVID-19 and the ICC later made the restriction permanent in some formats)
- Drying the ball with a cloth or towel
- Removing mud from the ball
- Protecting the shiny side by not dropping it deliberately on rough ground
What Is Illegal Ball Tampering?
- Using an artificial substance on the ball (lip balm, sunscreen, bottle-top, fingernail)
- Rubbing the ball on rough ground to accelerate deterioration
- Lifting the seam with a fingernail
- Using sandpaper, tape, or any abrasive on the ball's surface
- Deliberately wetting the ball with any liquid other than sweat or permitted saliva
Penalties for Ball Tampering
In-match penalties include five runs awarded to the batting side and replacement of the ball with one of similar condition. Post-match, the ICC Code of Conduct governs additional sanctions. Players found guilty of ball tampering can be suspended for multiple matches, fined, and in extreme cases — particularly if it is a systematic or premeditated team act — face longer bans. The ICC has categorised ball tampering as a serious breach, with penalties escalating for repeat offenders.
Frequently asked questions
Is applying sweat still legal after the saliva ban?
Sweat is permitted. The ICC banned saliva application specifically due to concerns about its potential to transfer pathogens on the ball surface. Players can continue to polish the ball with sweat only.
Can umpires check the ball for tampering during a match?
Yes. Umpires can inspect the ball at any time and must do so when a complaint is raised. If they find evidence of tampering, they apply the penalties and replace the ball.
Does ball tampering produce a significant playing advantage?
Yes. Artificially altering the ball can produce reverse swing much earlier than natural wear would allow, giving fast bowlers movement in conditions where the ball should be too soft to swing. The advantage is significant enough to have motivated some of cricket's most serious conduct incidents.
