In cricket, a penalty run is a type of extra. It is a run awarded to one team for various breaches of the Laws by the other team, generally related to unfair play or player conduct. Many of these penalties have been added since 2000. Penalties are awarded under Law 41 for Unfair Play [1] and, since 2017 under Law 42 for Players' Conduct [2]
It has been suggested that penalty runs could be imposed for slow over rates.[3]
"The committee feels that in-match five-run penalties would be the best deterrent to slow over rates," a statement said.
