achievement of a cricketer out first ball for zero in both innings
Duck (cricket) To be dismissed for nought in both innings of the same two-innings match is to be dismissed for a pair,[18] because the two noughts together are thought to resemble a pair of spectacles; the longer form is occasionally used.[19] To be dismissed first ball in both innings (i.e., two golden ducks) is to suffer the indignity of making a king pair.[11]
