Shot in two body parts (8)
I believe the answer is:
backhand
'shot' is the definition.
(type of shot in tennis)
'two body parts' is the wordplay.
'two body parts' can mean two replacements for 'body part'.
'body part' becomes 'back' ('back' is part of 'body').
'body part' becomes 'hand' (hand is a kind of body part).
'back'+'hand'='BACKHAND'
'in' is the link.
(Other definitions for backhand that I've seen before include "tennis side" , "Tennis stroke" , "shot, sportingly?" , "stroke, in court" , "shot from behind" .)
