Boundary (cricket)

The boundary is the edge of the playing field, or the physical object (often a rope) marking the edge of the field. In low-level matches, a series of plastic cones are sometimes used. Since the early 2000s, the boundaries at professional matches are often a series of padded cushions carrying sponsors' logos strung along a rope. If it is accidentally moved during play (such as by a fielder sliding into the rope in an attempt to stop the ball) the boundary is considered to remain at the point where that object first stood.

A traditional boundary rope

When the cricket ball is inside the boundary, it is live. When the ball is touching the boundary, grounded beyond the boundary, or being touched by a fielder who is himself either touching the boundary or grounded beyond it, it is dead and the batting side usually scores 4 or 6 runs for hitting the ball over the boundary. Because of this rule, fielders near the boundary attempting to intercept the ball while running or diving often flick the ball back in to the field of play rather than pick it up directly, because their momentum could carry them beyond the rope while holding the ball. They then return to the field to pick the ball up and throw it back to the bowler.

A law change in 2010 declared that a fielder could not jump from behind the boundary and, while airborne, parry the ball back on to the field.[1][2]

A boundary is the scoring of four or six runs from a single delivery with the ball reaching or crossing the boundary of the playing field. Occasionally there is an erroneous use of the term boundary as a synonym for a "four". For example, sometimes commentators say such as "There were seven boundaries and three sixes in the innings." The correct terminology would be "There were ten boundaries in the innings of which seven were fours and three were sixes."

Four runs are scored if the ball bounces before touching or going over the edge of the field and six runs if it does not bounce before passing over the boundary in the air. These events are known as a four or a six respectively. When this happens the runs are automatically added to the batsman's and his team's score and the ball becomes dead. If the ball did not touch the bat or a hand holding the bat, four runs are scored as the relevant type of extra instead; six runs cannot be scored as extras, even if the ball clears the boundary, which is in any case extremely unlikely. Prior to 1910, six runs were only awarded for hits out of the ground,[3] with five runs awarded for clearing the boundary.[4]

Four runs (or more) can also be scored by hitting the ball into the outfield and running between the wickets. Four runs scored in this way is referred to as an "all run four" and is not counted as a boundary.

Four runs are scored as overthrows if a fielder gathers the ball and then throws it so that no other fielder can gather it before it reaches the boundary. In this case, the batsman who hit the ball scores however many runs the batsmen had run up to that time, plus four additional runs, and it is counted as a boundary. If the ball has not come off the bat or hand holding the bat, then the runs are classified as 'extras' and are added to the team's score but not to the score of any individual batsman.

The scoring of a four or six by a good aggressive shot displays a certain amount of mastery by the batsman over the bowler, and is usually greeted by applause from the spectators. Fours resulting from an edged stroke, or from a shot that did not come off as the batsman intended, are considered bad luck to the bowler. As a batsman plays himself in and becomes more confident as his innings progresses, the proportion of his runs scored in boundaries often rises.

An average first-class match usually sees between 50 and 150 boundary fours. Sixes are less common, and usually fewer than 10 (and sometimes none) will be scored in the course of a match (especially a Test match).
