In cricket, a one-Test wonder is usually a cricketer who is only selected for one Test match during his career and never represents his country again. This is not necessarily due to a poor performance and can be for numerous reasons, such as injury or strong competition from other players.[1][2][3] The term is also used in rugby.[4]
More rarely, the term may refer to a player who has played in more than one Test, but was very successful only once. Examples include the bowlers Narendra Hirwani of India[5] and Bob Massie of Australia,[6] both of whom took eight wickets in each innings of their debut matches, but then failed to live up to their early promise. Spin bowler Ashton Agar of Australia played just 5 tests, taking 9 wickets, but his most notable contribution was in his first test and with the bat as he scored 98 on debut as the final Australian batsman, breaking multiple records including being the first test player to score a half-century as a number eleven batsman on debut and the highest score by any number eleven batsman.[7][8]
