Kept a record that's scratched (6)
I believe the answer is:
scored
'scratched' is the definition.
(I've seen this in another clue)
'kept a record' is the wordplay.
I cannot really see how this works, but
'record' could be 'score' (scoring is a kind of recording) and 'score' is located in the answer.
A single letter 'd' 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).
'that's' is the link.
Can you help me to learn more?
(Other definitions for scored that I've seen before include "Made runs" , "Got a goal" , "Coders (anag)" , "graded" , "Cut" .)
