What is reverse swing and how do I bowl it?

Reverse swing is one of cricket’s great old-ball weapons. It is fast, late, deceptive and, when executed well, extremely difficult for a batter to line up. In simple terms, reverse swing is when the ball swings in the opposite direction to the way the seam is pointing. Conventional swing usually follows the seam angle; reverse swing goes the other way. A 2024 Cambridge review of cricket-ball aerodynamics defines reverse swing as the ball deviating away from the direction the seam is pointing. 

At Gray-Nicolls, we think of reverse swing as a skill that sits at the intersection of craft, patience and discipline. It is not simply about grabbing an old ball and hoping it moves. It comes from legal ball care, repeatable wrist position, control of line and length, and the ability to disguise what is coming.

James Anderson, England’s greatest swing bowler and the most successful fast bowler in Test history with 704 wickets, is one of the best modern examples of that craft. He was never just a “new-ball” bowler. As his career developed, he became a master of changing method: conventional swing, wobble seam, cutters, dry spells, and reverse swing when conditions demanded it.

What is reverse swing?

Reverse swing happens when an older ball moves through the air in the opposite direction to its seam angle. With conventional swing, a right-arm bowler angling the seam towards the slips would usually expect the ball to move away from a right-handed batter. With reverse swing, that same seam angle can make the ball tail back in towards the pads and stumps.

That is why reverse swing feels so dangerous. The batter may read the seam, shape for one movement, and then find the ball moving late the other way.

In one sentence: reverse swing is old-ball swing where the ball moves opposite to the seam direction, often late in its flight.

Why does the ball reverse?

Reverse swing depends on the condition of the ball and the way air moves around it. As the ball gets older, one side can become rougher while the other side is kept smoother and shinier. That contrast changes the airflow around the two sides of the ball.

The Cambridge review explains that different magnitudes of reverse swing depend on the condition of both sides of the ball. It also notes that reverse swing is maximised when one side is rougher while the other remains smooth; if both sides become too rough, the amount of reverse swing can reduce. 

From a coaching point of view, that means three things matter most:

• The ball must be old enough, dry enough and worn enough.
• One side must be legally maintained better than the other.
• The bowler must deliver the ball with a strong wrist and stable seam.

Reverse swing is not magic. It is repeatable, but only when the ball, bowler and conditions line up.

Is reverse swing legal?

Yes. Reverse swing is completely legal. Illegally changing the condition of the ball is not.

This distinction matters. MCC Law 41.3 allows fielders to polish the ball on clothing provided no artificial substance is used, the only natural substance used is sweat, and no time is wasted. The same Law also allows mud to be removed under umpire supervision and a wet ball to be dried on an approved cloth. Any other action that changes the condition of the ball can be treated as unfair. 

So the rule for bowlers is simple: look after the ball, but do it properly. Keep one side dry and polished within the Laws. Do not pick the seam. Do not scratch the surface.

Reverse swing should be earned, not manufactured.

Reverse swing vs conventional swing

A useful coaching cue is this: with a genuinely reversing ball, expect the ball to move towards the smoother/shinier side and away from the seam angle. Sachin Tendulkar, in his analysis of Anderson’s rare “reverse swing reverse” variation, described reverse swing as moving in the direction of the shiny side, while highlighting how Anderson used wrist position to make the batter misread the movement. 

What James Anderson teaches us about reverse swing

James Anderson’s career is a case study in how elite bowlers keep learning. In a long technical interview with The Cricket Monthly, Anderson discussed outswing, inswing, wobble seam and reverse swing, explaining that he spent years refining grip, seam position and release. He also said reverse swing required a different feel from conventional swing, and recalled using it effectively in tough overseas conditions such as Galle and India. 

Anderson has also spoken about learning from Zaheer Khan, especially how Zaheer used reverse swing and disguised the ball in his run-up. That is an important lesson: reverse swing is not only about physics. It is also about what the batter sees, when they see it, and whether your action gives the delivery away. 

The Anderson model gives us four coaching lessons:

1. Practise both directions. Anderson did not become a swing bowler by accident. He repeated the skill until he trusted it.
2. Hide the clue, not the crime. Disguising the shiny side in the run-up is tactical. Illegally altering the ball is not.
3. Keep your wrist strong. Reverse swing becomes dangerous when the release looks the same until very late.
4. Have a plan. Anderson’s old-ball success came from knowing when to attack, when to bowl dry, and when to use the crease.

Key coaching points for bowling reverse swing

• Use an old, legal ball. Reverse swing is more likely once the ball has natural wear and one side is smoother than the other.
• Protect one side properly. Polish on clothing using sweat only, keep it dry, and never use artificial substances or deliberate damage. 
• Grip the ball like a fast bowler first. A basic coaching-manual grip starts with the thumb underneath and the first two fingers on top, with the seam upright. 
• Keep the seam stable. If the seam wobbles too much, the ball may not swing consistently.
• Keep the wrist firm and behind the ball. A collapsed wrist kills control.
• Aim fuller than you think. Reverse swing is most dangerous when the batter has to play.
• Target the stumps. Bowled and LBW are the classic reverse-swing dismissals.
• Do not chase magic every ball. Bowl a repeatable stock delivery first, then use the reverse-swing ball as a wicket-taking weapon.
• Use disguise. Do not show the smooth side too early in the run-up.
• Do not sacrifice your action. Young bowlers should not twist, sling or force their body shape just to make the ball reverse.

How do I bowl reverse swing?

Step 1: Start with the right ball

You need a ball that has aged naturally. In club cricket, that might mean waiting until the ball is 25, 35 or 45 overs old. Sometimes it will not reverse at all. A damp outfield, soft square or wet ball can make reverse swing very difficult. Anderson has spoken about moisture ruining the work put into preparing a ball for reverse swing. 

The ball should have:

• One side that is smoother and shinier.
• One side that is rougher through natural wear.
• A seam that is still prominent enough to grip and present.
• A dry surface.

Step 2: Use a simple fast-bowling grip

Start with your normal seam-bowling grip. First two fingers either side of the seam. Thumb underneath. Ball held firmly but not squeezed.

Coaching resources consistently emphasise a vertical seam, fingers either side of the seam and the hand staying behind the ball for clean release. 

Step 3: Choose the delivery

For most right-arm bowlers to a right-handed batter, the best starting point is the reverse inswinger.

That usually means:

• Seam angled slightly towards the slips.
• Smooth/shiny side towards leg side.
• Target line around off stump or middle-and-off.
• Full length, bringing bowled and LBW into play.

If the ball reverses, it should tail back in late. If it does not reverse, it may behave like a conventional outswinger. That is why practice matters: you must learn what the ball is doing on that day.

Step 4: Keep your action repeatable

Do not announce the reverse-swing ball with a completely different run-up or release. Your run-up, gather and arm speed should look as close to your stock ball as possible.

Anderson’s career is a reminder that the best swing bowlers are not guessing. They are reading conditions, repeating an action and making subtle adjustments. In his interview, he talked about experimenting with seam position and using trial and error to understand what worked on a given day. 

Step 5: Bowl fuller and make the batter play

Reverse swing loses value if the batter can leave it. A coaching article from Century Cricket Coaching makes this point for swing bowling generally: when the ball is moving, bowl straighter and fuller enough to make the batter play. 

The same principle applies to reverse swing. Your best attacking lengths are:

• Full top-of-off length.
• Full middle-and-off length.
• Yorker length.
• Full wide line only as a variation, not the stock ball.

The old-ball dream dismissal is simple: start the ball outside off stump, make the batter commit, then hit pad or stump as it tails in.

Common reverse-swing mistakes

1. Trying to bowl it too early

Not every old ball reverses, and almost no new ball will reverse in the way bowlers imagine. Let the ball age. Read the conditions. Do not force it.

2. Damaging the ball illegally

This is the biggest red line. Reverse swing is a skill. Ball tampering is an offence. The MCC Laws are clear that players must not take action that changes the condition of the ball outside permitted methods. 

3. Bowling too short

Reverse swing is usually most threatening when full. If you bang the ball halfway down, the batter has time to adjust and the movement may be wasted.

4. Losing the wrist

A weak wrist makes the seam fall away and turns reverse swing into guesswork. Keep the wrist firm, fingers behind the ball and follow-through towards the target.

5. Starting too wide

A big hooping reverse-swing ball looks great, but if it starts too wide the batter leaves it. Start straighter. Make them play.

6. Slowing down too much

Reverse swing generally rewards pace. Anderson agreed in his technical interview that reverse swing usually needs more speed than gentle medium pace to be fully effective. Young bowlers should still prioritise safe technique and control before chasing speed.

How to set up a batter with reverse swing

The classic set-up is simple:

1. Bowl two or three balls around fourth stump.
2. Make the batter think the ball is holding its line or moving away.
3. Bring the next ball fuller and straighter.
4. Let the old ball tail into pad or stump.

For a right-arm bowler to a right-handed batter, the attacking plan is usually:

• Mid-off and mid-on straighter.
• Catcher in front of square if the batter drives early.
• Fine leg and deep square adjusted for the inswinger.
• Slip or catching cover depending on whether the ball is also going away.

Reverse swing works best when field, line and length all tell the same story. Do not bowl an LBW ball with a field set for wide outswing. Do not bowl a fourth-stump ball with everyone waiting for the straight one.

Can junior and club bowlers learn reverse swing?

Yes, but with realistic expectations. Younger players should first learn:

• Safe action.
• Straight arm.
• Balanced run-up.
• Upright seam.
• Target control.
• Bowling a consistent length.

A coaching-manual approach to bowling starts with the basics: side-on alignment, non-bowling arm up, bowling arm coming over straight, and follow-through towards the target. Those fundamentals matter more than any advanced variation.

Once a bowler can repeat those basics, reverse swing becomes an extension of their skillset rather than a trick.

Final word from Gray-Nicolls

Reverse swing is one of cricket’s most exciting skills because it rewards patience. You cannot demand it from the ball. You have to prepare legally, bowl with control, and recognise the moment when the old ball is ready to move.

The best lesson from James Anderson is not simply that he could swing the ball both ways. It is that he kept adding layers to his game. He practised, experimented, learned from other great bowlers and adapted to different conditions. That is what young bowlers should take from reverse swing.

Master the basics first. Look after the ball properly. Keep the wrist strong. Bowl full. Make the batter play.

When the ball starts to tail late, cricket becomes a very different game.

FAQs

What is reverse swing in cricket?

Reverse swing is when an older cricket ball swings in the opposite direction to the way the seam is pointing. It is most commonly associated with fast bowlers using an old, dry ball.

How do you bowl reverse swing?

Use an old ball with one side smoother than the other, keep the seam upright, maintain a strong wrist, angle the seam, and bowl full enough to make the batter play. The movement should go opposite to the seam angle.

Is reverse swing legal?

Yes. Reverse swing is legal. Illegally changing the condition of the ball is not. Players may polish the ball on clothing using sweat only, remove mud under umpire supervision and dry a wet ball on an approved cloth. 

Do you need to bowl fast to reverse swing the ball?

Pace helps. At elite level, reverse swing is usually more effective at higher speeds. Club bowlers should focus first on wrist position, seam control and accuracy rather than forcing extra pace.

What length should I bowl for reverse swing?

Fuller lengths are best. Aim at top of off stump, middle-and-off, or yorker length. Reverse swing is most dangerous when the batter has to play.

Who is a good bowler to watch for reverse swing?

James Anderson is a superb modern example, especially because he combined conventional swing, reverse swing, wobble seam and tactical control. He has also spoken about learning reverse-swing skills from Zaheer Khan.
