Cricket has always had a knack of creating idiosyncracies which require new laws; think Bodyline, Mankading or Hawkeye.
Steven Finn's bowling action in England's T20 win over New Zealand may also result in a new law.
Finn produced the bowling performance of the match, taking three for 16 from his four overs. His wickets included Martin Guptill and Brendon McCullum in the six-over powerplay, followed by Ross Taylor. However, his efforts were tainted by inadvertently breaking the stumps with his knee three times during delivery.
The current law (which was decided pre-tournament in meetings between the International Cricket Council, team managements and captains) says the first time such an accident occurs should be exonerated; any subsequent stump upsets result in dead balls.
The law is designed to help the batsman because of the supposed distraction any dismantling of the opposing stumps creates during delivery. Last night it became evident the law needs to change.
