UDRS

The umpire decision review system (briefly called UDRS or DRS) is currently a new technology-based system to be used in the sport of cricket. This system was first used for the sole purpose of reviewing the controversial decisions given by the umpires in the field in the event of the batsman being dismissed or not in Test cricket. The new review system was officially launched by the International Cricket Council on November 24, 2009 during the first Test between New Zealand and Pakistan at the University Oval in Dunedin. In ODIs, it was first used in the England series against Australia for the first time in January 2011.

system

During each match, each team is allowed to request two failed reviews per innings. A fielding team can use this system to counter the decision to "not give out" and a batting team to defend "out". When the captain of the fielding team or the batsman is dismissed, he challenges the decision by indicating "T" with the hands. Once the challenge is accepted, the third umpire reviews the game after accepting it and granting it. Umpires for the decisions regarding some close matters such as line decisions (to determine run out and stumping) and to cross the boundary line R can request from them, the challenge can be used in those situations, which can result in the outcome: For example, to determine if the ball sealed is a perfect catch or not (the batsman Touching the bat or glove and touching the ground before being caught by the fielder) or the value of being dismissed by a tossed ball leg before wicket (In the straight line on the ground or in the off side, the stage food and the batter's pad hit the path in the same line in which it collides with the wicket). Then the third umpire informs the umpire in the ground that its analysis is the original decision Supports, is contrary to the decision or is inconclusive. Then the umpire in the grounds makes a final decision: either re-indicates the earlier judgment or canceling the decision being changed indicates the correct sign. Each team can use the referral until it uses unsuccessful reviews of its part. Under the DRS rule only wrong decisions are changed, in the case of decisions in which both possibilities may occur, the original decision (decision of the umpire on the ground) does not change.

When an LBW decision is not given out is evaluated and if the replays indicate that the ball is taken in the pads 2.5 meters away from the wicket, the umpires have to consider another feature too. : Distance traveled by the ball between pitching and hitting the pad. If the distance (between pitching and pad) is less than 40 cm and if the ball has to travel more than 2.5m to reach the stump, then the decision not to be given out by any umpire in the field is not out Will remain It has also been decided that if the batsman is more than 3.5m away from the wicket, the decision of not re-knot will not be changed. In only one situation, an LBW decision will be changed in the side of the bowler if the batsman is 2.5m away from the wicket, if the distance is less than 3.5 m and the distance between the pitching and the impact point is less than 40 cm. In that case, some part of the ball will hit the middle stump and the entire ball will collide with the stump on the bottom of the gilli. In those cases, where the original decision is given out, the distance of 2.5m or 40cm is not applicable, because in that situation, the umpire should show the ball completely leaving the stump completely by Hawk Eye to undo his decision. Should. Reaction

Generally the system has received positive feedback from players and trainers, although there has been some criticism as well. The West Indies famous player Joel Garner has called this system a nautanki. Ramnaresh Sarwan, another West Indian player, said he was not a supporter of the experimental referral system. Former umpire Dicky Bird also criticized the system as saying that it ignores the right of the umpire in the grounds. The Board of Control for Cricket in India (BCCI) is not in favor of using this system. ICC World Cup 2011

The first referral of the World Cup came into use after the fourth ball was bowled in the second innings. Shantakumar Sreesanth of India had thrown a yorker ball and the umpire called it not out. Dhoni sent it to the TV umpire and a replay showed that it might have missed the leg stumps, so the original decision was justified. The match made the debut of the controversial umpire referral system in World Cup cricket. UDRS was used in the exciting encounter between India and England in Bangalore when the M.S. Dhoni became annoyed with this system and said that it is a mix of human and technology, on which the ICC replied that before deciding on this, players should know the technique. The ICC has revised the guidelines of the 2.5 meter rule that umpires should consider important points regarding this. Pakistan successfully used DRS against Australia in their match of Group A. A ball thrown by Mohammad Hafeez took the outer edge of the Australian captain Ricky Ponting's bat and the umpire called it not out. The DRS system changed this decision. This was a turning point in the match. After the match, the Australian captain admitted that the ball had taken the outer edge of his bat, but he said that he remained on the crease because he was never a walker - (to be self-out). Ponting said that "there was no doubt about putting bat - I knew that I had hit the ball". "But as usual, I wait for the umpire to get me out, I've always played the game like this, he has been criticized for showing the decisions and poor game spirit of Ricky Ponting. Notes

According to the latest UDRS modification, although the batsman is playing very fast (more than 2.5 meters) then he will be given out, provided that according to the TV reply some part of the ball will hit the middle stumps (if All other LBW rules are still correct)
