Small number of shots in fight (4)
I believe the answer is:
spar
'fight' is the definition.
(sparring is a kind of fighting)
'small number of shots' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'number of shots' becomes 'par' (golf).
's'+'par'='SPAR'
'in' is the link.
(Other definitions for spar that I've seen before include "Length of wood" , "Raps with wooden beam" , "Close friend" , "Round pole to support sail" , "Mast - boom - gaff" .)
