Tom in band played a racket sport (9)
I believe the answer is:
badminton
'a racket sport' is the definition.
(I've seen this before)
'tom in band played' is the wordplay.
'played' indicates an anagram (letters playing around).
'tom'+'in'+'band'='tominband'
'tominband' with letters rearranged gives 'BADMINTON'.
(Other definitions for badminton that I've seen before include "One sport" , "Game using shuttlecock" , "Game played with rackets" , "Racket game with shuttlecock" , "in which rackets are involved" .)
