Top cricket game in garden (6)
I believe the answer is:
hoodie
'top' is the definition.
(type of clothing top )
'cricket game in garden' is the wordplay.
'cricket game' becomes 'odi' (abbreviation for one day international).
'in' means one lot of letters goes inside another.
'garden' becomes 'hoe' (I've seen this in other clues).
'odi' put into 'hoe' is 'HOODIE'.
(Other definitions for hoodie that I've seen before include "Casual jacket" , "Sweatshirt with head-covering" , "Crow; cowled youth" , "Youth's top" , "'Uniform' often associated with ASBO offenders (variant spelling)" .)
