The Slower Ball in Cricket — Disguise, Types and How to Bowl It
The slower ball is pace bowling's most deceptive weapon. Learn the different types of slower balls — off-cutter, leg-cutter, knuckle ball, palm ball — how they deceive batters, and when they are most effective.
The slower ball is a delivery bowled with the same action as a fast delivery but at significantly reduced pace — typically 15–25km/h slower. The batter, having read a fast-bowling action, commits early to a shot planned for a quicker delivery and either mistimes the ball completely or gets bowled clean through the gate.
Why the slower ball works
The human eye determines the expected speed of a delivery from the bowler's run-up and release point, not from tracking the ball through the air. A slower ball with an identical run-up and delivery action appears to be coming at full pace until it is almost at the batter — by which time the batter has already committed to an aggressive stroke. The mismatch between expectation and reality causes the dismissal.
Types of slower balls
- Off-cutter — the fingers cut across the seam on release (from off to leg). This reduces pace and creates lateral movement off the pitch. James Anderson and Stuart Broad use this extensively.
- Leg-cutter — fingers cut across the seam from leg to off. Moves away from a right-hander off the pitch. Effective on slower or dry pitches.
- Knuckle ball — the ball is held with the knuckles (not the fingertips), reducing the grip on the surface and significantly reducing pace. Made famous by Dale Steyn and now used widely in T20 death bowling.
- Palm ball — held deep in the palm rather than the fingers, drastically reducing pace. A variation less common at the highest level.
- Back-of-the-hand slower ball — the wrist rolls over so the back of the hand faces the batter at release, reducing pace and sometimes creating opposite movement. Jasprit Bumrah's slower balls use variations of this action.
When to bowl the slower ball
The slower ball is most effective in limited-overs cricket during the death overs (overs 16–20 in T20, 45–50 in ODIs), when batters are swinging hard at everything. It is also effective as a change of pace in the middle overs to disrupt a batter's rhythm. Against a batter who is 'timing' everything on a flat pitch, a well-disguised slower ball is the best way to create a mistimed shot.
Frequently asked questions
What is a slower ball in cricket?
A slower ball is a delivery bowled by a pace bowler with the same action as a fast delivery but at significantly reduced speed — typically 15–25km/h slower. The batter commits to a shot expecting pace and mistimes or misses the ball.
What is a knuckle ball in cricket?
A knuckle ball is a type of slower delivery where the bowler grips the ball with the knuckles instead of the fingertips, significantly reducing pace and making the ball float or slide through without the usual seam movement.
Which bowlers are best at the slower ball?
Jasprit Bumrah (India) is considered the best slower ball bowler in modern cricket, with multiple variations including back-of-hand and knuckle ball. Rashid Khan (Afghanistan) uses a disguised slower googly in T20 cricket. Dale Steyn (South Africa) was famous for his knuckle ball in death overs.
Why is the slower ball especially effective in T20 cricket?
In T20 death overs, batters are trying to hit boundaries against every delivery and setting up for big swings. A well-disguised slower ball hit too early in the shot results in a mishit or top-edge catch — one of the most common T20 dismissals.
