We all know the key to top quality spin bowling is to bowl a consistent line and length. But what does that actually mean?
First we need to figure out where is the best length to bowl.
We want a length that is full enough that the batsman is forced to come forward, but not so full that he is able to reach the ball on the half volley without mis-hitting it.
Consider that the average spin bowler delivers the ball at approximately 50mph, and that after bouncing the speed of the ball is reduced by about 50%. This translates to a speed of about 10 metres a second. The average reaction time of a human is 0.2s. If we pitch the ball within 2 metres of the batsman, then he will be unable to play back as he would simply not have time to react to any movement off the pitch.
Therefore the maximum distance away from the batsman's stumps that we should land the ball, given that he will move back one foot when playing back, is approximately 11 foot. Anything shorter than 11 foot and the batsman will be able to play comfortably off the back foot.
How about minimum distance?
A batsman playing on the front foot normally plays the ball about 3 feet in front of his crease. The ideal location to pitch the ball is the one at which the ball has just turned enough to hit or just miss the edge of the bat. On a normal pitch, we will find the ball turning something in the order of 5 degrees, which translates to about 1 inch sideways for each foot after bouncing.
Therefore we need to pitch the ball between 2 and 4 foot in front of the bat (8 to 10 foot from the stumps) in order to take the edge.
On a turning track, a ball pitching only a foot in front of the bat would be sufficient to threaten the edge.
The best length on this pitch would therefore be between 7 and 9 foot from the batsman's stumps. So the spin bowler has an area of about 4 feet, or just over a metre, in which to aim: anything inside this will pose the batsman problems.
No matter the pitch, the ball will not always turn a consistent amount. This variability of turn is major positive factor for the spinner. If he can't predict what will happen, how can the batsman be expected to?
A competent batsman will most likely play the percentages and play for a small amount of turn when defending off the front foot, reducing the likelihood of a ball that turns just 1 or 2 inches catching the edge. However, the inadvertent result of this is that now both the big turning delivery and the straight ball are the potential wicket taking deliveries. The spinner must always take advantage of this by ensuring that every time the ball beats the bat, whether the inside edge or outside edge, then there is a decent probability that the batsman will be dismissed.
Batsmen are able to play more assertively when they feel comfortable that they are able to use their pad as a second line of defence without the risk of being dismissed lbw. This is why it’s important for a spin bowler to constantly attack the stumps with either the big spinning delivery, the straight ball, or both.
We therefore want to keep as many deliveries as possible ending up in the danger zone: either on the stumps for a chance of bowled or lbw or within 6 inches of off stump for a likely caught behind chance.
On a spinning pitch, then 10 degrees of turn will translate to a difference of about 15 inches between the straight ball and the big turning delivery. So we need to take this into consideration when planning our line of attack.
If the ball is turning away from the batsman, the ideal stock line is to pitch the ball on middle and leg, with the straight delivery angled in towards leg stump. Spin the ball hard enough for the spinning delivery to hit or go past the top of off stump.
The batsman will then be forced to play down a middle stump line to defend against the spin, and this will mean that both the straight delivery and the big spinner will have a good chance of dismissing him.
The off spinner should ensure that his big spinning delivery is not wasted by constantly turning down the leg side. This means that he needs to pitch the ball just outside off stump. A sensible batsman will then play down the line of off stump to defend against the spin, leaving both the big spinner and the straight ball as wicket-taking options.
Isolated to its most fundamental point, cricket could be described as
the duel between a bowler tempting a batsman to drive and a batsman
trying to ignore that temptation.
Knowing when to attack and when to defend is crucial to the success of good spinners, and that comes only with experience. Terry Jenner talks to Nagraj Gollapudi

Terry Jenner played nine Tests for Australia in the 1970s but it is as a coach, and specifically as Shane Warne's mentor and the man Warne turned to in a crisis, that he is better known. Jenner said that his CV wouldn't be complete without a trip to India, the spiritual home of spin bowling, and this September he finally made it when he was invited by the MAC Spin Foundation to train youngsters in Chennai. Jenner spoke at length to Cricinfo on the art and craft of spin bowling in general and legspin in particular. What follows is the first in a two-part interview.
"Most of the time the art of the spin bowler is to get the batsman to look to drive you. That's where your wickets come"
How has the role of spin changed over the decades you've watched cricket?
The limited-overs game has made the major change to spin bowling. When I started playing, for example, you used to break partnerships in the first couple of the days of the match and then on the last couple of days you were expected to play more of a major role. But in recent years, with the entry of Shane Warne, who came on on the first day of the Test and completely dominated on good pitches, it has sort of changed the specs that way.
But the difficulty I'm reading at the moment is that captains and coaches seem to be of the opinion that spin bowlers are there either to rest the pace bowlers or to just keep it tight; they are not allowed to risk runs to gain rewards. That's the biggest change.
In the 1960s, when I first started, you were allowed to get hit around the park a bit, as long as you managed to get wickets - it was based more on your strike-rate than how many runs you went for. So limited-overs cricket has influenced bowlers to bowl a negative line and not the attacking line, and I don't know with the advent of Twenty20 how we'll advance. We will never go back, unfortunately, to the likes of Warne and the wrist-spinners before him who went for runs but the quality was more.
What are the challenges of being a spinner in modern cricket?
The huge challenge is just getting to bowl at club level through to first-class level. When you get to the first-class level they tend to you allow you to bowl, but once you get to bowl, instead of allowing you to be a free spirit, you are restricted to men around the bat - push it through, don't let the batsman play the stroke, don't free their arms up ... all those modern thoughts on how the spinner should bowl.
Do spinners spin the ball less these days?
The capacity to spin is still there, but to spin it you actually have to flight it up, and if you flight it up there's always that risk of over-pitching and the batsman getting you on the full, and therefore the risk of runs being scored. So if you consider the general mentality of a spinner trying to bowl dot balls and bowl defensive lines, then you can't spin it.
I'll give you an example of an offspin bowler bowling at middle and leg. How far does he want to spin it? If he needs to spin it, he needs to bowl a foot outside the off stump and spin it back, but if he has to bowl a defensive line then he sacrifices the spin, otherwise he'll be just bowling down the leg side.
It's impossible for you to try and take a wicket every ball, but when you're really young that's what you do - you just try and spin it as hard as you can and take the consequences, and that usually means you don't get to bowl many overs. The art of improving is when you learn how to get into your overs, get out of your overs, and use the middle deliveries to attack
Legspinners bowling at leg stump or just outside - there's been so few over the years capable of spinning the ball from just outside leg past off, yet that's the line they tend to bowl. So I don't think they spin it any less; the capacity to spin is still wonderful. I still see little kids spinning the ball a long way. I take the little kids over to watch the big kids bowl and I say, "Have a look: the big kids are all running in off big, long runs, jumping high in the air and firing it down there, and more importantly going straight." And I say to the little kids, "They once were like you. And one of you who hangs on to the spin all the way through is the one that's gonna go forward."
Great spinners have always bowled at the batsman and not to the batsman. But the trend these days is that spinners are becoming increasingly defensive.
First of all they play him [the young spinner] out of his age group. Earlier the idea of finding a good, young talent, when people identified one, was that they didn't move him up and play him in the higher grade or in the higher age group. There was no different age-group cricket around back then, and if you were a youngster you went into the seniors and you played in the bottom grade and then you played there for a few years while you learned the craft and then they moved you to the next grade. So you kept going till you came out the other end and that could've been anywhere around age 19, 20, 21 or whatever. Now the expectation is that by the time you are 16 or 17 you are supposed to be mastering this craft.
It's a long apprenticeship. If you find a good 10- or 11-year-old, he needs to have a ten-year apprenticeship at least. There's a rule of thumb here that says that if the best there's ever been, which is Shane Warne - and there is every reason to believe he is - sort of started to strike his best at 23-24, what makes you think we can find 18- or 19-year-olds to do it today? I mean, he [Warne] has only been out of the game for half an hour and yet we're already expecting kids to step up to the plate much, much before they are ready.
It's a game of patience with spin bowlers and developing them. It's so important that we are patient in helping them, understanding their need for patience, at the same time understanding from outside the fence - as coach, captain etc. We need to understand them and allow them to be scored off, allow them to learn how to defend themselves, allow them to understand that there are times when you do need to defend. But most of the time the art of the spin bowler is to get the batsman to look to drive you. That's where your wickets come, that's where you spin it most.
Warne said you never imposed yourself as a coach.
With Warne, when I first met him he bowled me a legbreak which spun nearly two feet-plus, and I was just in awe. All I wanted to do was try and help that young man become the best he could be, just to help him understand his gift, understand what he had, and to that end I never tried to change him. That's what he meant by me never imposing myself. We established a good relationship based on the basics of bowling and his basics were always pretty good. Over the years whenever he wandered away from them, we worked it back to them. There were lot of times over his career where, having a bowled a lot of overs, some bad habits had come in. It was not a case of standing over him. I was just making him aware of where he was at the moment and how he could be back to where he was when he was spinning them and curving them. His trust was the most important gift that he gave me, and it's an important thing for a coach to understand not to breach that trust. That trust isn't about secrets, it's about the trust of the information you give him, that it won't harm him, and that was our relationship.
I don't think of myself as an authority on spin bowling. I see myself as a coach who's developed a solid learning by watching and working with the best that's been, and a lot of other developing spinners. So I'm in a terrific business-class seat because I get to see a lot of this stuff and learn from it, and of course I've spoken to Richie Benaud quite a lot over the years.
Shane would speak to Abdul Qadir and he would feed back to me what Abdul Qadir said. Most people relate your knowledge to how many wickets you took and I don't think that's relevant. I think it's your capacity to learn and deliver, to communicate that what you've learned back to people.
From the outside it seems like there is a problem of over-coaching these days.
There are so many coaches now. We have specialist coaches, general coaches, we've got sports science and psychology. Coaching has changed.
Shane, in his retirement speech, referred to me as his technical coach (by which he meant technique), as Dr Phil [the psychologist on the Oprah Winfrey Show]. That means when he wanted someone to talk to, I was the bouncing board. He said the most uplifting thing ever said about me: that whenever he rang me, when he hung the phone up he always felt better for having made the call.
"Think high, spin up" was the first mantra you shared with Warne. What does it mean?
When I first met Shane his arm was quite low, and back then, given I had no genuine experience of coaching spin, I asked Richie Benaud and made him aware of this young Shane Warne fellow and asked him about the shoulder being low. Richie said, "As long as he spins it up from the hand, it'll be fine." But later, when we tried to introduce variations, we talked about the topspinner and I said to Shane, "You're gonna have to get your shoulder up to get that topspinner to spin over the top, otherwise it spins down low and it won't produce any shape." So when he got back to his mark the trigger in his mind was "think high, spin up", and when he did that he spun up over the ball and developed the topspinner. Quite often even in the case of the legbreak it was "think high, spin up" because his arm tended to get low, especially after his shoulder operation.
Can you explain the risk-for-reward theory that you teach youngsters about?
This is part of learning the art and craft. It's impossible for you to try and take a wicket every ball, but when you're really young that's what you do - you just try and spin it as hard as you can and take the consequences, and that usually means you don't get to bowl many overs. The art of improving is when you learn how to get into your overs, get out of your overs, and use the middle deliveries in an over to attack. I called them the risk and reward balls in an over. In other words, you do risk runs off those deliveries but you can also gain rewards.
There's been no one in the time that I've been around who could theoretically bowl six wicket-taking balls an over other than SK Warne. The likes of [Anil] Kumble ... he's trying to keep the lines tight and keep you at home, keep you at home while he works on you, but he's not trying to get you out every ball, he's working a plan.
The thing about excellent or great bowlers is that they rarely go for a four or a six off the last delivery. That is the point I make to kids, explaining how a mug like me used to continually go for a four or six off the last ball of the over while trying to get a wicket so I could stay on. And when you do that, that's the last thing your captain remembers, that's the last thing your team-mates remember, it's the last thing the selectors remember. So to that end you are better off bowling a quicker ball in line with the stumps which limits the batsman's opportunities to attack. So what I'm saying is, there's always a time when you need to defend, but you've got to know how to attack and that's why you need such a long apprenticeship.
Warne said the most uplifting thing ever said about me: that whenever he rang me, when he hung the phone up he always felt better for having made the call
Richie Benaud writes in his book that his dad told him to keep it simple and concentrate on perfecting the stock ball. Benaud says that you shouldn't even think about learning the flipper before you have mastered the legbreak, top spinner and wrong'un. Do you agree?
I totally agree with what Richie said. If you don't have a stock ball, what is the variation? You know what I'm saying? There are five different deliveries a legbreak bowler can bowl, but Warne said on more than one occasion that because of natural variation you can bowl six different legbreaks in an over; what's important is the line and length that you are bowling that encourages the batsman to get out of his comfort zone or intimidates him, and that's the key to it all. Richie spun his legbreak a small amount by comparison with Warne but because of that his use of the slider and the flipper were mostly effective because he bowled middle- and middle-and-off lines, whereas Warne was leg stump, outside leg stump.
Richie's a wise man and in the days he played there were eight-ball overs here in Australia. If you went for four an over, you were considered to be a pretty handy bowler. If you go for four an over now, it's expensive - that's because it's six-ball overs. But Richie was a great example of somebody who knew his strengths and worked on whatever weaknesses he might've had. He knew he wasn't a massive spinner of the ball, therefore his line and length had to be impeccable, and he worked around that.
In fact, in his autobiography Warne writes, "What matters is not always how many deliveries you possess, but how many the batsmen thinks you have."
That's the mystery of spin, isn't it? I remember, every Test series Warnie would come out with a mystery ball or something like that, but the truth is there are only so many balls that you can really bowl - you can't look like you're bowling a legbreak and bowl an offbreak.
Sonny Ramdhin was very difficult to read as he bowled with his sleeves down back in the 1950s; he had an unique grip and unique way of releasing the ball, as does Murali [Muttiah Muralitharan]. What they do with their wrists, it's very difficult to pick between the offbreak and the legbreak. Generally a legbreak bowler has to locate his wrist in a position to enhance the spin in the direction he wants the ball to go, which means the batsman should be able to see the relocation of the wrist.
In part two of his interview on the art of spin bowling, Terry Jenner looks at the damage caused to young spinners by the curbs placed on their attacking instincts. He also surveys the current slow-bowling landscape and appraises the leading practitioners around.
"Most spin bowlers have enormous attacking instinct, which gets suppressed by various captains and coaches" Nagraj Gollapudi
Bishan Bedi once said that a lot of bowling is done in the mind. Would you say that spin bowling requires the most mental energy of all the cricketing arts?
The thing about that is Bishan Bedi - who has, what, 260-odd Test wickets? - bowled against some of the very best players ever to go around the game. He had at his fingertips the control of spin and pace. Now, when you've got that, when you've developed that ability, then it's just about when to use them, how to use them, so therefore it becomes a matter of the brain. You can't have the brain dominating your game when you haven't got the capacity to bowl a legbreak or an offbreak where you want it to land. So that's why you have to practise those stock deliveries until it becomes just natural for you - almost like you can land them where you want them to land blindfolded, and then it just becomes mind over matter. Then the brain does take over.
There's nothing better than watching a quality spin bowler of any yolk - left-hand, right-hand - working on a quality batsman who knows he needs to break the bowler's rhythm or he might lose his wicket. That contest is a battle of minds then, because the quality batsman's got the technique and the quality bowler's got the capacity to bowl the balls where he wants to, within reason. So Bishan is exactly right.
What came naturally to someone like Bedi was flight. How important is flight in spin bowling?
When I was very young someone said to me, "You never beat a batsman off the pitch unless you first beat him in the air." Some people think that's an old-fashioned way of bowling. Once, at a conference in England, at Telford, Bishan said "Spin is in the air and break is off the pitch", which supported exactly what that guy told me 40 years ago. On top of that Bedi said stumping was his favourite dismissal because you had beaten the batsman in the air and then off the pitch. You wouldn't get too many coaches out there today who would endorse that remark because they don't necessarily understand what spin really is.
When you appraised the trainees in Chennai [at the MAC Spin Foundation], you said if they can separate the one-day cricket shown on TV and the one-day cricket played at school level, then there is a chance a good spinner will come along.
What I was telling them was: when you bowl a ball that's fairly flat and short of a length and the batsman goes back and pushes it to the off side, the whole team claps because no run was scored off it. Then you come in and toss the next one up and the batsman drives it to cover and it's still no run, but no one applauds it; they breathe a sigh of relief. That's the lack of understanding we have within teams about the role of the spin bowler. You should be applauding when he has invited the batsman to drive because that's what courage is, that's where the skill is, that's where the spin is, and that's where the wickets come. Bowling short of a length, that's the role of a medium pacer, part-timer. Most spin bowlers have enormous attacking instinct which gets suppressed by various captains, coaches and ideological thoughts in clubs and teams.
You talked at the beginning of the interview about the importance of being patient with a spinner. But isn't it true that the spinner gets another chance even if he gets hit, but the batsman never does?
I don't think you can compare them that way. If the spinner gets hit, he gets taken off. If he goes for 10 or 12 off an over, they take him off. Batsmen have got lots of things in their favour.
What I mean by patience is that to develop the craft takes a lot of overs, lots of balls in the nets, lots of target bowling. And you don't always get a bowl. Even if you are doing all this week-in, week-out, you don't always get to bowl, so you need to be patient. And then one day you walk into the ground and finally they toss you the ball. It is very easy to behave in a hungry, desperate manner because you think, "At last, I've got the ball." And you forget all the good things you do and suddenly try to get a wicket every ball because it's your only hope of getting into the game and staying on. The result is, you don't actually stay on and you don't get more games. So the patience, which is what you learn as you go along, can only come about if the spinner is allowed to develop at his pace instead of us pushing him up the rung because we think we've found one at last.
How much of a role does attitude play?
Attitude is an interesting thing. Depends on how you refer to it - whether it's attitude to bowling, attitude to being hit, attitude to the game itself.
When you bowl a ball that's fairly flat and short of a length and the batsman goes back and pushes it to the off side, the whole team claps because no run was scored off it. Then you come in and toss the next one up and the batsman drives it to cover and it's still no run, but no one applauds it; they breathe a sigh of relief
When Warne was asked what a legspin bowler needs more than anything else, he said, "Love". What he meant was love and understanding. They need someone to put their arm around them and say, "Mate, its okay, tomorrow is another day." Because you get thumped, mate. When you are trying to spin the ball from the back of your hand and land it in an area that's a very small target, that takes a lot of skill, and it also requires the patience to develop that skill. That's what I mean by patience, and the patience also needs to be with the coach, the captain, and whoever else is working with this young person, and the parents, who need to understand that he is not going to develop overnight.
And pushing him up the grade before he is ready isn't necessarily a great reward for him because that puts pressure on him all the time. Any person who plays under pressure all the time, ultimately the majority of them break. That's not what you want, you want them to come through feeling sure, scoring lots of wins, feeling good about themselves, recognising their role in the team, and having their team-mates recognise their role.
I don't think people - coaches, selectors - let the spin bowler know what his role actually is. He gets in the team and suddenly he gets to bowl and is told, "Here's the field, bowl to this", and in his mind he can't bowl.
Could you talk about contemporary spinners - Anil Kumble, Harbhajan Singh, Daniel Vettori, Monty Panesar, and Muttiah Muralitharan of course?
Of all the spinners today, the one I admire most of all is Vettori. He has come to Australia on two or three occasions and on each occasion he has troubled the Australian batsmen. He is a man who doesn't spin it a lot but he has an amazing ability to change the pace, to force the batsman into thinking he can drive it, but suddenly they have to check their stroke. And that's skill. If you haven't got lots of spin, then you've got to have the subtlety of change of pace.
And, of course, there is Kumble. I always marvel at the fact that he has worked his career around mainly containment and at the same time bowled enough wicket-taking balls to get to 566 wickets. That's a skill in itself. He is such a humble person as well and I admire him.
I marvel a little bit at Murali's wrist because it is very clever what he does with that, but to the naked eye I can't tell what is 15 degrees and what's not. I've just got to accept the word above us. All I know is that it would be very difficult to coach someone else to bowl like Murali. So we've got to put him in a significant list of one-offs - I hate to use the word "freak" - that probably won't be repeated.
I don't see enough of Harbhajan Singh - he is in and out of the Indian side. What I will say is that when I do see him bowl, I love the position of the seam. He has a beautiful seam position.
I love the way Stuart MacGill spins the ball. He is quite fearless in his capacity to spin the ball.
I love the energy that young [Piyush] Chawla displays in his bowling. The enthusiasm and the rawness, if you like. This is what I mean when I talk about pushing the boundaries. He is 18, playing limited-overs cricket, and at the moment he is bowling leggies and wrong'uns and I think that's terrific. But I hope the time doesn't come when he no longer has to spin the ball. When he tries to hold his place against Harbhajan Singh, for example. To do that he has to fire them in much quicker. He is already around the 80kph mark, which is quite healthy for a 18-year-old boy, but he still spins it at that pace, so it's fine. But ultimately if he is encouraged to bowl at a speed at which he doesn't spin the ball, that would be the sad part.
That's why I say this, there are lots of spinners around but it's the young, developing spinners who are probably suffering from all the stuff from television that encourages defence as a means to being successful as a spinner.
Monty is an outstanding prospect. You've got to look at how a guy can improve. He has done very, very well but how can he improve? He has got to have a change-up, a change of pace. At the moment, if you look at the speed gun in any given over from Monty, it's 56.2mph on average every ball. So he bowls the same ball; his line, his length, everything is impeccable, but then when it's time to knock over a tail, a couple of times he has been caught short because he has not been able to vary his pace. I think Monty is such an intelligent bowler and person that he will be in the nets working on that to try and make sure he can invite the lower order to have a go at him and not just try and bowl them out. That probably is his area of concern; the rest of it is outstanding.
What would you say are the attributes of a good spinner? Courage, skill, patience, unpredictability, and spin. You get bits and pieces of all those, but if you have got spin then there is always a chance you can develop the other areas. For all the brilliant things that people saw Warne do, his greatest strength was the size of the heart, and that you couldn't see.
Being an aggressive spinner is not about bowling flat and fast. Quite the opposite, and you only have to look at veteran bowlers operate in Twenty20 to see that
Aakash Chopra
April 14, 2011
Grounds are getting smaller, wickets flatter, bats thicker. And just to make it tougher for bowlers, the format of the game has got shorter. As if the rule book doesn't already favour batsmen, these "innovations" have stacked the odds against bowlers higher still. But while it has ostensibly become tougher for bowlers to succeed, good ones will always have their say.
Who are these "good bowlers", though? In the pre-Twenty20 era these were men who could simply bowl quick, for a batsman needed special skills to get on top of someone bowling at 145kph. It was widely believed that the shorter the format, the smaller the role of a spinner. In fact, the only way for a spinner to survive in Twenty20 was to bowl quick and flat, or so it was believed for the longest time.
But a look at the spinners in action in the current IPL is enough to tell you an entirely different story. Spinners who're bowling slower in the air are ruling the roost.
Is it only about bowling slow or it there more to it? Let's take a look at what's making these bowlers ever so successful.
A big heart
While fast bowlers are the stingy kind, who hate runs being scored off them, spinners are more often than not advised to be generous and to always be prepared to get hit. Bishan Bedi would tell his wards that a straight six is always hit off a good ball and one should never feel bad about it. Having a big heart doesn't mean that you should stop caring about getting hit; rather that you shouldn't chicken out and start bowling flatter.
Suraj Randiv could easily have bowled flatter when he was hit for two consecutive sixes by Manoj Tiwary in the first match, but he showed the heart to flight another delivery, and got the better of his opponent. You rarely see Daniel Vettori or Shane Warne take a step back whenever they come under the hammer. Instead of thinking of ways to restrict damage, they try to plot a dismissal.
Slow down the pace
Most young spinners don't realise that the quicker one bowls, the easier it gets for the batsman, who doesn't have to move his feet to get to the pitch of the ball and smother the spin. You can do fairly well while staying inside the crease, and small errors of judgement aren't fatal either, as long as you're playing straight.
The slower the delivery, the tougher it is to generate power to clear the fence, but there are no such issues if the bowler is sending down darts. In fact, even rotating the strike is a lot easier if the bowler is bowling quicker, for you need great hands to manoeuvre the slower delivery.
Yes, it is perhaps easier to find the blockhole if you're bowling quick, but you're not really going to get under the bat and bowl the batsman, since you don't have that sort of pace.
Also, if you bowl quick, the chances of getting turn off the surface (unless it is really abrasive) are minimal. You must flight the ball and bowl slow to allow the ball to grip the pitch and get purchase.
Attack the batsman
Mushtaq Ahmed tells young spinners that they need to have the attitude of fast bowlers to attack batsmen.
Attacking the batsman is often misinterpreted as bowling quick. That's what the fast men do; you hit them for a six and you're almost guaranteed a bouncer next ball. For a spinner, attacking has a different meaning - going slower and enticing the batsman.
Bowling slow must not be confused with giving the ball more air. The trajectory can still remain flat while bowling slow. Some batsmen are quick to put on their dancing shoes the moment the ball goes above eye level while standing in the stance, so it's important to keep the ball below their eye level and yet not bowl quick. Vettori does it with consummate ease and reaps rewards. He rarely bowls quick; he relies on changing the pace and length to deceive the batsman. And if the batsman is rooted to the crease and is reluctant to use his feet, you can flight the ball.
Add variety
The best way to not just survive but thrive as a spinner is to keep evolving.
Anil Kumble not only slowed down his pace but also added a googly to his armoury in the latter half of his career. Muttiah Muralitharan added another dimension to his bowling when he started bowling the doosra. Suraj Randiv stands tall at the crease and extracts a bit of extra bounce. Ravi Ashwin has mastered the carrom ball.
Instead of learning to undercut the ball (which is obviously a lot easier to develop), it's worth developing a doosra, a carrom ball or some other variety.
Young kids must understand that when you bowl flatter-faster deliveries, the ball behaves somewhat like a hard ball does on a concrete surface, skidding off the pitch. Slower balls, on the other hand, act like tennis balls, with far more bounce.
Up and coming spinners need to set their priorities right. They can either bend the front knee to reduce height while taking the arm away from the ear to bowl darts, or learn from the likes of Warne, Vettori, Murali and the like to succeed in all formats, provided the basics are right.
