Part of the wicket

The stumps are three vertical posts which support two bails

Bail (cricket)

In the sport of cricket, a bail is one of the two smaller sticks placed on top of the three stumps to form a wicket. The bails are used to determine when the wicket is broken, which in turn is one of the critical factors in determining whether a batsman is out bowled, stumped, run out or hit wicket...

. The stumps and bails are usually made of wood, and together form a wicket

Cricket pitch

. The overall width of each wicket is 9 inches (22.9 cm).

Each stump is 28 inches (71.1 cm) tall with maximum and minimum diameters of 1 inches (3.81 cm) and 1 inches (3.49 cm). They have a spike at one end for inserting into the ground, and the other end has a U-shaped 'through groove'

 to provide a resting place for the bails.

Each stump is referred to by a specific name:

• Off stump is the stump on the off side of the wicket (the same side as the batsman's bat).
• Middle (Lie) stump is the centre stump, on the lie of the wicket.
• Leg stump is the stump on the on side of the wicket (the same side as the batsman's legs).

These names are relative to the batsman, so a right-handed batsman's leg stump becomes the off stump when a left-handed player is batting.

In modern professional play, the stumps are often emblazoned with a sponsor's logo. Although they are too far away from spectators to be seen, such logos are visible on television

 coverage.

For professional matches, often one or more of the stumps is hollow and contains a small television camera. This is aligned vertically, but can view through a small window on the side of the stump via a mirror. The so-called stump-cam gives a unique view of play for action replays, particularly when a batsman is bowled.

Manner of dismissing a batsman

In cricket

Cricket

Cricket is a bat-and-ball game played between two teams of 11 players on an oval-shaped field, at the centre of which is a rectangular 22-yard long pitch.

, a batsman can be out stumped if:

• the wicket-keeper
  Wicket-keeper

   puts down the wicket, while the batsman is:
  • out of his ground (because he has moved down the pitch beyond the popping crease, usually in an attempt to hit the ball); and
  • not attempting a run.

Being "out of his ground" is defined as not having any part of the batsman's body or his bat touching the ground behind the crease - i.e., if his bat is slightly elevated from the floor despite being behind the crease, or if his foot is on the crease line itself but not completely across it and touching the ground behind it, then he would be considered out (if stumped). One of the fielding team (such as the wicket-keeper himself) must appeal for the wicket by asking the umpire. The appeal is normally directed to the square-leg umpire, who would be in the best position to adjudicate on the appeal.

. It is usually seen when a medium or slow bowler is bowling, as with fast bowlers a wicket-keeper takes the ball too far back from the wicket to attempt a stumping. It requires co-operation between a bowler and wicket-keeper: the bowler must induce the batsman to move out of his ground, and the wicket-keeper must catch and break the wicket before the batsman realises he has missed the ball and makes his ground, i.e. places the bat or part of his body on the ground back behind the popping crease

Crease (cricket)

. If the bails are removed before the wicket-keeper has the ball, the batsman can still be stumped if the wicket-keeper removes one of the stumps from the ground, while holding the ball in his hand.

  : using either the ball itself or a hand or arm that is in possession of the ball. Note that since the ball itself can legally put down the wicket, a stumping is still valid even if the ball merely rebounds from the 'keeper and breaks the wicket, even though never controlled by him.
• The wicket-keeper must allow the ball to pass the stumps before taking it, unless it has touched either bat or batsman first.

End of the day's play
