Slower Ball
Also known as: change-up, slower delivery, off-pace delivery
The slower ball is a variation delivery bowled by a pace bowler at significantly reduced speed — usually 20–30 km/h below full pace — to deceive a batter expecting the standard pace.
Pace bowlers develop slower balls to create deception without changing their action. Variations include the off-cutter, the leg-cutter, the back-of-the-hand delivery (ball held behind the hand at release), the knuckleball (ball gripped on the knuckles), and the scrambled seam. The key is that the bowling action looks identical to the full-pace delivery — the deception comes from a subtle change in finger position or wrist angle at release. If a batter commits early to the expected pace, the slower ball causes them to play through the ball too early, resulting in a top edge, a missed ball, or a catch to a deep fielder. The slower ball is a crucial weapon in death-overs bowling in limited-overs cricket.
Example
The fast bowler delivers a back-of-the-hand slower ball at 20 km/h below full pace; the batter, expecting full pace, swings early and top-edges to deep mid-wicket.
Why it matters
The slower ball is the pace bowler's most important limited-overs variation. SwingVantage's cricket analysis (in development) will detect arm speed and wrist position differences to help bowlers disguise this delivery effectively.

- Death-Overs BowlingDeath-overs bowling is the skill of bowling the final overs of a limited-overs innings — typically overs 17–20 in T20 or overs 41–50 in one-day cricket — when the batting team is trying to hit every ball for a boundary.
- Off-CutterThe off-cutter is a pace bowling variation where the ball is cut off the index finger and middle finger to spin towards the off side off the pitch, acting like a slow off-break without a full-length spin action.
- Leg-CutterThe leg-cutter is a pace bowling variation where the ball is cut off the middle and ring fingers to move towards the leg side off the pitch, acting like a slow leg-break.
- Good LengthA good-length delivery is one that pitches at the spot that forces the batter to be uncertain whether to play off the front foot or the back foot — the most dangerous line for any bowler.
