Does he make his mark as an arranger? (6)
I believe the answer is:
scorer
'arranger?' is the definition.
(thesaurus)
'does he make his mark' is the wordplay.
I cannot really see how this works, but
'mark' could be 'score' (synonyms) and 'score' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'as an' acts as a link.
Can you help me to learn more?
(Other definitions for scorer that I've seen before include "He scratches" , "Cricket official" , "One getting a goal" , "Keeper of the tally" , "He puts the ball in the net" .)
