FAQ
Frequently Asked Questions
It is a single, closed compound word: knuckleball.
No, by definition, a knuckleball is thrown with low velocity (typically 55-70 mph) to minimize spin. High speed creates stabilizing spin, defeating its purpose.
No. Cricket has deliveries that behave unpredictably (e.g., a googly or a 'zooter'), but the mechanics and term 'knuckleball' are specific to baseball. The closest cricket analogy in terms of unpredictable movement might be a 'flipper' or a poorly bowled leg break.
The name likely comes from the original grip, where the ball is held with the knuckles or fingernails pressed into it to prevent spin, as opposed to the fingertips. An alternative name, the 'knuckle curve', is a different pitch with spin.
