Law 41.3 of the game, updated and put into effect on October 1, 2022, says: “When cricket resumed following the onset of Covid-19, playing conditions were written in most forms of the game stating that applying saliva to the ball was no longer permitted. MCC’s research found that this had little or no impact on the amount of swing the bowlers were getting. Players were using sweat to polish the ball, and this was equally effective.
