Fourth in Nicolas Cage’s golf tournament (4)
I believe the answer is:
open
'golf tournament' is the definition.
(the Open is a golf tournament)
'fourth in nicolas cage's' is the wordplay.
'fourth in nicolas' becomes 'o' (4th letter of 'nicolas').
'cage' becomes 'pen' (both can mean an enclosure).
'o'+'pen'='OPEN'
(Other definitions for open that I've seen before include "Freely accessible" , "unsealed" , "Allowing access" , "Not shut or secret" , "Agape" .)
