Squeeze in a game (6)
I believe the answer is:
squash
I believe this clue is a double definition.
'squeeze' is the first definition.
(synonyms)
'game' is the second definition.
(I know that squash is a type of court game)
'in a' acts as a link.
(Other definitions for squash that I've seen before include "Vegetable, drink and ball game" , "Crush, squelch" , "Game; crush, squeeze" , "Racquet sport" , "Fruit eaten as a vegetable" .)
