The 2022 T20 World Cup is going to start in Australia on Sunday, October 16 in Melbourne. This is the eighth edition of the premier tournament, in its 15-year history, having kicked off in 2007. Since the first tournament, the ICC, which is the governing body of cricket, has made all kinds of rule changes in T20 cricket.
While there have been some new changes for 2022 as well, we take a look at the complete list in the last 15 years, and how they have affected cricket in their own way.
Bowl-out
The bowl-out rule first came to use in the 2007 ICC World Cup. When two teams tied a match, five different players from both sides had to bowl to empty wickets. Under this rule, Team India defeated Pakistan.
But, this rule was removed after 2007.
Super over
In the 2009 T20 World Cup, the Super Over was implemented for the first time. According to this rule, if a match is tied, then both teams will play an over each. Whichever team score more runs will be declared the winner.
An extra addition was the tiebreaker rule. In this rule, if the match is tied even in the super over, then there will be another super over, which will continue until the winning team is found.
DRS
The previous T20 World Cup 2021 was the first tournament during which Decision Review System (DRS) was used.
Concussion rule
This rule also came into effect for the first time in 2021. When a player suffers a major head injury, he can be replaced by another player if he suffers a concussion.
Strike to not change in caught outs
If a batter is caught out after hitting a shot and he has crossed the non-striker, then the new batter will take strike. This is different from the earlier rule that saw the non-strike batter take strike in case the two batters crossed over before the ball was caught.
Saliva ban
Earlier, fast bowlers used saliva to help reverse swing the ball. But since Coronavirus became a regular norm, the ICC has completely banned the use of saliva.
Slow overrate penalties
If the fielding team is unable to finish the match in the stipulated time, then an additional fielder will have to be placed inside the 30-yard circle. This means that instead of five, only four fielders will be able to field outside the circle.
New batter's rule
If one batter is out then the next batter has to come to the crease within 90 seconds. In ODIs and Tests, the time allotted is 2 minutes.
Dead ball rule
ICC believes that when the batter is playing a shot then at that point his body must be inside the pitch. If this does not happen then the ball will be declared as a dead ball.
Five run penalty
If a player of the fielding team commits an intentional wrongful act during the bowler's run-up, then five runs will be given as a penalty to the batting team.
Mankading is no longer illegal
The ICC has now recognized the wicket of a batter standing at the non-striker's end and his dismissal by the bowler. This out has now been categorized as a run-out by the ICC.
How a batter cannot be out
Earlier, if a batter comes slightly ahead of the crease then the bowler could throw and run him out. Now the ICC has made declared such the ball as a dead ball.
