Slight wound is no handicap (7)
I believe the answer is:
scratch
I believe this is a double definition.
'slight wound' is the first definition.
(I've seen this before)
'no handicap' is the second definition.
(scratch handicap is a zero handicap in golf)
'is' acts as a link.
(Other definitions for scratch that I've seen before include "Improvised" , "Score - postpone indefinitely" , "Score, mark; cancel" , "score with > no handicap given" , "Superficial damage; withdraw" .)
