In the sport of cricket, ball tampering is an action in which a fielder illegally alters the condition of the ball. Under Law 42, subsection 3 of the Laws of Cricket, the ball may be polished without the use of an artificial substance, may be dried with a towel if it is wet, and have mud removed from it under supervision; all other actions which alter the condition of the ball are illegal.
