Small game: deer? (4)

I believe the answer is:

stag

'deer?' is the definition.
(stag is a kind of deer)

'small game' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'game' becomes 'tag' (children's playground game).
's'+'tag'='STAG'

(Other definitions for stag that I've seen before include "Male-only" , "speculator wanting quick profit" , "This party is for men only" , "Hunted animal" , "Hart" .)

I've seen this clue in The Everyman puzzle in The Observer.
