Prize money not starting as long as the batting lasts (7)
I believe the answer is:
innings
'long as the batting lasts' is the definition.
I can't judge whether this definition defines the answer.
'prize money not starting' is the wordplay.
'prize money' becomes 'winnings' (money won).
'not starting' means to remove the first letter.
'winnings' with its initial letter taken off is 'INNINGS'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for innings that I've seen before include "Period of batting in cricket" , "Time at the wicket" , "Time at the crease - a good one's a long life" , "Time spent batting" , "(At cricket) a turn to bat" .)
