An arm ball is a type of delivery in cricket. It is a variation delivery bowled by an off spin bowler or slow left-arm orthodox bowler. It is the finger spin equivalent of a wrist spinner's slider or zooter.
In contrast to the stock delivery, an arm ball is delivered with rolling the fingers down the back of the ball on release. This means the ball has backspin on it, and it does not turn appreciably off the pitch. Instead, it travels straight on in the direction of the arm, from which it derives its name. However, by keeping the seam upright, the bowler can also hope to obtain some outswing away from the right-handed batsman, thereby confusing the batsman who expects the ball to turn.
The arm ball is often used as a surprise variation by an off spinner who is turning the ball considerably. A complacent or poorly skilled batsman playing for the expected spin can be taken by surprise and get out bowled or lbw, or edge the ball with the outside edge of the bat to offer a catch to the wicket-keeper or slip fielders. Offspinners Harbhajan Singh, Graeme Swann, Shakib Al Hasan, Imad Wasim , Ravindra Jadeja and more recently Axar Patel are some spinners who have excelled in bowling arm balls.
The arm ball has also been employed with a great deal of success over the years by left-arm orthodox bowlers. In this case, the stock ball will turn away from the right-handed batsman and the arm-ball would swing in, allowing the bowler to beat the inside edge of the bat and attack the stumps. Hedley Verity in particular was well known for his fast inswinging arm-ball, often bowled at yorker length. Ravindra Jadeja provided an amazing display of arm balls against England and Australia during India's 2016–17 home season. His arm balls were hugely effective on some of the flat pitches where there was little turn, and while playing for that little turn, batsmen were deceived and edged it. On spinning pitches he utilised the rough for his spinning deliveries, occasionally getting an arm ball in to disturb the batsman.
Daniel Vettori and Derek Underwood are other examples of left-arm orthodox bowlers renowned for use of an inswinging arm ball to good effect. Vettori famously bowled Darren Maddy with a perfect arm ball at the Oval Test Match of 1999. Having set up Maddy with two balls breaking away from him, Vettori then bowled a perfectly disguised arm ball. Thinking the ball was another stock delivery, Maddy left the ball, only to see it swing in and crash into his off-stump
Leg spin is a type of spin bowling in cricket. A leg spinner bowls right-arm with a wrist spin action. The leg spinner's normal delivery causes the ball to spin from right to left in the cricket pitch when the ball bounces. For a right-handed batsman, that is away from the leg side, and this is where it gets the name leg break, meaning it breaks away from the leg. The turn is mostly when the ball pitches.
Left-arm orthodox spin, Left-arm off spin also known as slow left-arm orthodox spin bowling, is a type of left-arm finger spin bowling in the sport of cricket. Left-arm orthodox spin is bowled by a left-arm bowler using the fingers to spin the ball from right to left of the cricket pitch.
Left-arm unorthodox spin, also known as slow left-arm wrist-spin, is a type of spin bowling in the sport of cricket. Left-arm unorthodox spin bowlers use wrist spin to spin the ball, and make it deviate, or 'turn' from left to right after pitching. The direction of turn is the same as that of a traditional right-handed off spin bowler, although the ball will usually turn more sharply due to the spin being imparted predominantly by the wrist. The delivery was sometimes historically called a chinaman.
The flipper is the name of a particular bowling delivery used in cricket, generally by a leg spin bowler. In essence it is a back spin ball. Squeezed out of the front of the hand with the thumb and first and second fingers, it keeps deceptively low after pitching and can accordingly be very difficult to play. The flipper is comparable to a riseball in fast-pitch softball.
Off spin is a type of finger spin bowling in cricket. A bowler who uses this technique is called an off spinner. Off spinners are right-handed spin bowlers who use their fingers to spin the ball. Their normal delivery is an off break, which spins from left to right when the ball bounces on the pitch. For a right-handed batsman, this is from his off side to the leg side. The ball breaks away from the off side, hence the name 'off break'.
In the game of cricket, a googly refers to a type of delivery bowled by a right-arm leg spin bowler. The googly is a variation of the typical leg spin type of delivery, in that the cricket ball is presented from the bowler's hand in such a way that once the ball pitches, it deviates in the opposite direction of a leg spinning type of delivery. It has also been colloquially and affectionately referred to as the wrong'un, Bosie or Bosey, with those latter two eponyms referring to Bernard Bosanquet, the bowler who initially discovered and began using the googly.
A topspinner is a type of delivery bowled by a cricketer bowling either wrist spin or finger spin. In either case, the bowler imparts the ball with top spin by twisting it with his or her fingers prior to delivery. In both cases, the topspinner is the halfway house between the stock delivery and the wrong'un - in the wrist spinner's case his googly, and in the finger spinner's case his doosra.
This is a general glossary of the terminology used in the sport of cricket. Where words in a sentence are also defined elsewhere in this article, they appear in italics. Certain aspects of cricket terminology are explained in more detail in cricket statistics and the naming of fielding positions is explained at fielding (cricket).
A doosra is a particular type of delivery by an off-spin bowler in the sport of cricket. The doosra spins in the opposite direction to an off break, and aims to confuse the batsman into playing an unavoidable shot.
Pace bowling is one of two main approaches to bowling in the sport of cricket, the other being spin bowling. Practitioners of pace bowling are usually known as fast bowlers, quicks, or pacemen. They can also be referred to as a seam bowler, a swing bowler or a fast bowler who can swing it to reflect the predominant characteristic of their deliveries. Strictly speaking, a pure swing bowler does not need to have a high degree of pace, though dedicated medium-pace swing bowlers are rarely seen at Test level these days.
Spin bowling is a bowling technique in cricket, in which the ball is delivered slowly but with the potential to deviate sharply after bouncing, and the bowler is referred to as a spinner.
An outswinger is a type of delivery in the sport of cricket. It is bowled by swing bowlers.
An inswinger is a type of delivery in the sport of cricket. It is bowled by swing bowlers.
A leg cutter is a type of delivery in the sport of cricket. It is bowled by fast bowlers.
An off cutter is a type of delivery in the game of cricket. It is bowled by fast bowlers.
In the sport of cricket there are two broad categories of bowlers: pace and spin. Pace bowlers rely mostly on the speed of the ball to dismiss batsmen, whereas spin bowlers rely on the rotation of the ball.
In the sport of cricket, a slower ball is a slower-than-usual delivery from a fast bowler. The bowler's intention is to deceive the batsman into playing too early so that he either misses the ball completely or hits it high up in the air to offer an easy catch. It is analogous to a changeup in baseball.
A delivery or ball in cricket is a single action of bowling a cricket ball toward the batsman. These terms can also refer to the events that occur after the ball is bowled while the ball is not dead.
Wrist spin is a type of bowling in the sport of cricket. It refers to the cricket technique and specific hand movements associated with imparting a particular direction of spin to the cricket ball. The other spinning technique, usually used to spin the ball in the opposite direction, is finger spin. Wrist spin is bowled by releasing the ball from the back of the hand, so that it passes over the little finger. Done by a right-handed bowler, this imparts an anticlockwise rotation to the ball, as seen from the bowler's perspective; a left-handed wrist spinner rotates the ball clockwise.
Finger spin is a type of bowling in the sport of cricket. It refers to the cricket technique and specific hand movements associated with imparting a particular direction of spin to the cricket ball. The other spinning technique, generally used to spin the ball in the opposite direction, is wrist spin. Although there are exceptions, finger spinners generally turn the ball less than wrist spinners. However, because the technique is simpler and easier to master, finger spinners tend to be more accurate.
