Field knowledge to be a pro-fan
Circle: On the pitch where batters are batting, there is a 30-yard circle on the ground, which is used to maintain fielding restriction. When powerplays are under way, only a certain number of players can stand inside or outside the circle.
Crease: Refers to the line located 48 inches (1.21 metres) in front of the stumps and denotes the batter’s “safe ground” where he cannot be stumped or run out.
Duck: If a batter is out without scoring a run, it is called scoring a duck. If he is out on the first ball he faces, it is referred to as a “golden duck”.
Decision Review System (DRS): An electronic review system, available for both batting and fielding teams, in which they can question key decisions made by umpires where a player is declared out or not out. Teams are allowed two reviews per innings.
Duckworth-Lewis-Stern (DLS) Method: A mathematical calculation to calculate target scores when the rain interrupts the match. The formula is used for calculating the target score for a team batting second during a match which is interrupted by weather or any other reasons.
Hawk-Eye: A modern video technology that is used to aid DRS. It is essentially a computer-generated tracking technology with high-end cameras that track the path of the delivery and predict which way the ball would go. It is a key component of the DRS and all the major ICC-sanctioned tournaments are mandated to use DRS.
Innings: The length of time a team bats is called an innings. In a T-20 game, a maximum of 20 overs are allowed which constitute one innings.
Pitch: The most important part of the ground, the pitch is a 22-yard strip on which the bowler bowls and the batters bat. The pitch is made of mud, soil, and rock, and pitch conditions play a massive part in making play difficult for either batter or bowler.
Powerplay: A concept introduced in ODIs and T20 in 2005. While it has gone through multiple amendments, the current rule for ODIs states that 50 overs are divided into three blocks. The first block lasts for the first 10 overs of the innings, followed by the second which lasts from over 11 to 40, and then the final block of 10 overs. Fielding teams are allowed to keep only a certain number of fielders within the circle, according to which powerplay block is going on.
Run rate: Run rate or runs per over (RPO) is a simple mathematical calculation in which a team’s scoring rate is calculated by dividing the number of runs scored at any given time, after the number of overs they have played till then.
