Game; fruit (6)
I believe the answer is:
squash
I believe this clue is a double definition.
'game' is the first definition.
(squash is a kind of game)
'fruit' is the second definition.
(I've seen this before)
(Other definitions for squash that I've seen before include "Fruit drink; a ball game" , "Court game - marrow-like plant" , "Fruit eaten as a vegetable" , "Crush the ballgame?" , "court action" .)
