Lead shot originally found on pitch (4)
I believe the answer is:
star
'lead' is the definition.
(I know that lead can be written as star)
'shot originally found on pitch' is the wordplay.
'originally' says to take the initial letters.
'found on' means one lot of letters go next to another.
'pitch' becomes 'tar' (synonyms).
The initial letter of 'shot' is 's'.
's'+'tar'='STAR'
(Other definitions for star that I've seen before include "Leading actor in a show" , "Celebrity in the world of entertainment" , "White blaze on a horse's forehead" , "Famous player" , "Celestial point of light" .)
