enough velocity that the effect will take hold. Sarfraz Nawaz and Imran Khan are credited as two of the earliest exponents of reverse-swing in International cricket. Waqar Younis and Wasim Akram perfected the art of reverse-swing and inspired many to learn the art. An outswinger is a type of delivery of the ball in the sport of cricket. In such a delivery the ball curves—or "swings"—out and away from the batter's body and the wicket. By contrast, an inswinger swings in toward the batter and the wicket. Richard Hadlee, Malcolm Marshall, Dominic Cork, Dale Steyn and James Anderson are some of the bowlers who had the best outswingers of their time. Other tactics Pace bowlers frequently dismiss batsmen through variation and deception. A batter who has been "softened up" by a series of bouncers, which pitch nearer the bowler than normal and reach the batsman around head height, or even hit the batsman, may tend to play the next ball on the back foot, and thus be susceptible to a full-length yorker delivery that bounces at his toes. Many bowlers also develop a "slower ball"; these are bowled with the same arm action as their normal delivery, but come slower from the hand, usually due to the bowler gripping the ball differently or cocking his wrist at the last moment. With luck, the batsman will misread the pace, and will have finished his shot before the ball arrives. Other common variations include the leg cutter and off cutter, medium pace deliveries bowled with a spinner's wrist action, which can sometimes "turn" just like deliveries from a spinner. Steve Waugh is often credited as the bowler who pioneered and popularized the back of the hand slower deliveries and change of pace in order to baffle the batsmen. Spin bowlers Spin bowlers or spinners impart rotation to the ball to get a batsman out. The spin on the ball makes its movement hard to predict, particularly when it bounces, hence spin bowlers try to deceive batsmen into making a mistake. Speed is not crucial in spin bowling, and spinners tend to bowl in the slow-medium to medium-slow range, around 45-55 mph. There are two broad categories of spin bowling: wrist spin and finger spin. Wrist spin Wrist spinners are bowlers who use their wrists to spin the ball. A right-handed wrist spinner is known as a leg spinner and his or her
