Club in Cuba trendy (3)
I believe the answer is:
bat
'club' is the definition.
(as in sporting equipment)
'in cuba trendy' is the wordplay.
'in' says the answer is hidden in the clue.
'BAT' is hidden within 'cuba trendy'.
(Other definitions for bat that I've seen before include "Night flier" , "Cricket implement or flying mammal" , "Small mammal or cricket striker" , "Small flying mammal, may be vampire" , "Night-flyer" .)
