Turned up to sell game (4)
I believe the answer is:
golf
'game' is the definition.
(golf is a kind of game)
'turned up to sell' is the wordplay.
'turned up' says the letters should be written backwards.
'to sell' becomes 'flog' (I've seen this before).
'flog' in reverse letter order is 'GOLF'.
(Other definitions for golf that I've seen before include "Foxtrot follower" , "a few rounds?" , "Game played at Troon" , "Rory McIlroy's game" , "Eighteen-hole game" .)
