A delivery or ball in cricket is a single action of bowling a cricket ball towards the batsman. During play of the game, a member of the fielding team is designated as the bowler, and bowls deliveries towards the batsman. Six balls in a row constitutes an over, after which a different member of the fielding side takes over the role of bowler for the next over. The bowler delivers the ball from his or her end of the pitch towards the batsman standing at the opposite wicket at the other end of the pitch. Bowlers can be either left handed or right handed. This approach to their delivery, in addition to their decision of bowling around the wicket (from the sides of the wicket on the bowler’s end) or over the wicket is knowledge of which the umpire and the batsman are to be made aware. ==Types of delivery== Deliveries can be made by fast bowlers or by spin bowlers. Fast bowlers tend to make the ball either move off the pitch ("seam") or move through the air ("swing"), while spinners make the ball "turn" either toward a right-handed batsman (as in the case of off spin and left-arm unorthodox spin) or away from him (as in the case of leg spin and left-arm orthodox spin). The ball can bounce at different distances from the batsman, this is called the ''length'' of the delivery. It can range from a bouncer (often bouncing as high as the batsman's head) to a yorker (landing at his feet). There are many different types of delivery that a bowler can bowl. These deliveries vary by: technique, the hand the bowler bowls with, use of the fingers, use of the seam, how the ball is positioned in the hand, where the ball is pitched on the wicket, the speed of the ball, and the tactical intent of the bowler. *Leg spin deliveries and mirror equivalents for left arm unorthodox spin: * * Leg break * * Googly * * Topspinner * * Flipper * * Slider * * Flicker ball * Off spin deliveries and mirror equivalents for left arm orthodox spin: * * Off break * * Doosra * * Arm ball * * Topspinner * * Carrom ball * * Teesra * Fast bowling deliveries: * * Bouncer * * Inswinger * * Reverse swing * * Leg cutter * * Off cutter * * Outswinger * * Yorker * * Beamer (illegal) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Delivery (cricket)」の詳細全文を読む スポンサード リンク
