Explained: LBW rules and the controversial umpires’ call in DRS | Cricket News


NEW DELHI: According to the Marylebone Cricket Club (MCC), the guardian of the legal guidelines of the recreation, there are ten methods in which a batsman will be dismissed in cricket.
These are:
1. Bowled
2. Caught
3. Hit the ball twice
4. Hit-wicket
5. Leg earlier than wicket (LBW)
6. Obstructing the area
7. Run out
8. Stumped
9. Timed out.
10. Handled the ball.
Of all these legal guidelines, LBW has been certainly one of the most controversial and error-prone strategies of dismissal. For the longest time the on-field umpires determined whether or not a batsman was out LBW or not. It’s nonetheless finished that manner, besides since 2008 (when DRS was first launched in worldwide cricket) the gamers can now problem an on-field umpires choice, utilizing this technique.
Over the a long time, LBW is one rule that has seen a number of umpiring howlers. No different rule in cricket has seen as many adjustments as the LBW ones.
Law 36 states that: the batter is out LBW if the bowler delivers a official supply (not a no-ball), the ball pitches in line between wicket and wicket or on the off aspect of the striker’s wicket, the ball not having beforehand touched his/her bat, the striker intercepts the ball, both full-pitch or after pitching, with any a part of his/her particular person, the level of impression, even when above the degree of the bails, both is between wicket and wicket or if the striker has made no real try and play the ball with the bat, is between wicket and wicket or exterior the line of the off stump, however for the interception, the ball would have hit the wicket.
If the ball pitches exterior the leg stump of the batter, then the LBW dismissal is dominated out.
Over the years, LBW has been the most error-prone dismissal as a result of the umpires get solely a fraction of a second to make the choice. Sometimes the edge off the bat onto the pads is simply too near be noticed, generally the umpires fail to learn the trajectory of the supply and have dominated the batter out even when the ball goes over the stumps or vice-versa.
These dismissals, both manner, may probably change the course of the match and finally the consequence too.
But with the introduction of expertise, innovation got here in, motion replays grew to become part of the recreation. The on-field umpire began signalling for the third umpire to make run out choices and then Decision Review System (DRS) was launched in 2008.

According to the International Cricket Council (ICC), the DRS is a technology-based course of for aiding the match officers with their decision-making. On-field umpires might seek the advice of with the third umpire (an Umpire Review) and gamers might request that the third umpire contemplate a choice of the on-field umpires (a Player Review).
To decide, the DRS depends on ball monitoring (to estimate the trajectory of the ball) and snickometer (to see if there’s an edge off the bat onto the pad or not).

While the snickometer was seen as a welcome transfer, it’s the ball monitoring side that hit controversy. Ball monitoring traces the place the ball pitched, the level of impression of the ball on the pad and then the predicted path in the direction of the stumps.
The human-machine battle got here to the fore as a result of expertise can not make an ideal prediction of how a lot the ball will truly flip or bounce and whether or not the ball will go on to hit the stumps or not.
Some umpires stated the DRS undermines the worth of the on-field umpires, gamers doubted it due to the inconsistency in judging the spin and the bounce.
The Indian cricket board (BCCI) refused to simply accept DRS initially as a result of the predicted path after the ball hit the pad was not dependable. BCCI added that there was an opportunity that the operator makes an error whereas figuring out the level of impression of the ball on the pad.
To take away this glitch, Hawk-Eye, the ball-tracking expertise supplier, created Ultra-Edge, a sound based mostly, edge-detection system that would determine the level of impression extra precisely. Hawk-Eye claimed that Ultra-Edge can determine the body in which the ball hits the pad when there’s a sound of the ball hitting the pad or bat.
Satisfied, the BCCI agreed to make use of the DRS for the dwelling collection towards England in 2016-17. Before that, the solely occasions India had used the DRS was in ICC occasions.

As per the present rule, 50% of the ball needs to be hitting a minimum of certainly one of the three stumps for the batter to be adjudged LBW on overview, in case an umpire’s not out call has been challenged.
Many cricketers and cricket commentators have discovered this to be an odd rule, contemplating the ball even barely brushing the stumps is ideally sufficient to dislodge the bails, which successfully rules a batter out.

What we see usually is an on-field umpiring ruling a batter not-out on LBW and then replays displaying that the ball would have certainly gone on to hit the stumps. But as a result of it’s lower than 50%, the batter is deemed not out and the on-field umpire’s call stands.
In April final yr the ICC Board dominated that the contentious Umpire’s call rule will stay part of DRS.
Former India captain Anil Kumble, who was the ICC Cricket Committee Chairman at the moment had stated in an announcement – “The principle underpinning DRS was to correct clear errors in the game whilst ensuring the role of the umpire as the decision maker on the field of play was preserved, bearing in mind the element of prediction involved with the technology. Umpire’s Call allows that to happen, which is why it is important it remains.”
The Cricket Committee although authorised three adjustments to DRS and third umpire protocols to be adopted. “For LBW reviews, the height margin of the Wicket Zone will be lifted to the top of the stumps to ensure the same Umpire’s Call margin around the stumps for both height and width.
A player will be able to ask the umpire whether a genuine attempt has been made to play the ball before deciding to review an LBW decision.
The 3rd Umpire will check a replay of any short-run that has been called and correct any error prior to the next ball being bowled.” the ICC additional stated in a launch.
