A duck is a score of zero: a batter is dismissed without scoring a run. The name comes from the shape of the number on the scorecard, a zero that looks like a duck's egg.
The Types of Duck
- Golden duck: out first ball faced, the most embarrassing kind.
- Silver duck: out second ball faced.
- Diamond duck: run out without facing a single ball. The batter did nothing wrong except be at the non-striker's end.
Pair and King Pair
A pair is a duck in both innings of a Test or first-class match. A king pair is a golden duck in both: out first ball in each innings.
Does a Duck Count Against a Batter's Average?
Yes. A duck is a completed innings that adds zero runs, so it drags the batting average down. A batter who stays not out on zero has also not been dismissed, so it doesn't count as a completed innings.
Why the Egg?
The scoreboard symbol 0 looks like an egg, and "duck's egg" became "duck" in cricket slang over time. It's one of the oldest bits of cricket vocabulary still in everyday use.
