Racquet game (6)
I believe the answer is:
tennis
'racquet game' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tennis that I've seen before include "Sport with grand slams?" , "Henman's game" , "Table -, - elbow" , "Sent in to play the game, oddly" , "Medieval, originally French, sport, codified by the British" .)
