Mark Wood supporting principle of Duckworth-Lewis (4)
I believe the answer is:
dash
'mark' is the definition.
(dash is a kind of mark)
'wood supporting principle of duckworth-lewis' is the wordplay.
I cannot really understand how this works, but
'wood' could be 'ash' (wood from an ash tree) and 'ash' is located in the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dash that I've seen before include "hasty journey" , "Fly" , "Destroy (hopes); run" , "Hurl; rush" , "Discourage - suggestion - hurry" .)
