Just one delivery, then away for a rest (3,5)
I believe the answer is:
off break
'just one delivery' is the definition.
'off break' can be an answer for 'delivery' (cricket). I am unsure of the 'just one' bit.
'away for a rest' is the wordplay.
'away' becomes 'off' (synonyms).
'for' is a charade indicator (letters next to each other).
'a rest' becomes 'break' (I've seen this before).
'off'+'break'='OFF-BREAK'
'then' is the link.
Can you help me to learn more?
(Other definitions for off break that I've seen before include "Spinner's delivery" , "One result of bowling" , "Ball" .)
