Final dance in game (7)
I believe the answer is:
netball
'game' is the definition.
(netball is a kind of game)
'final dance' is the wordplay.
'final' becomes 'net' (synonyms).
'dance' becomes 'ball' (ball is a kind of dance).
'net'+'ball'='NETBALL'
'in' acts as a link.
(Other definitions for netball that I've seen before include "Seven-a-side team game -- all bent (anag)" , "Sport whose players wear bibs" , "Team sport" , "Team game for tall Ben" , "After this, you get to serve again" .)
