Further Away win (5)
I believe the answer is:
again
'further' is the definition.
(thesaurus)
'away win' is the wordplay.
'away' becomes 'a' (abbreviation as used in sports fixtures).
'win' becomes 'gain' ('gain' can be a synonym of 'win'**).
'a'+'gain'='AGAIN'
(Other definitions for again that I've seen before include "Anew" , "Here we go ___" , "repeat order" , "On the other hand" , "'Another time, once more (5)'" .)
