Capturing cricket trophy, ruffian spends big (6,3)
I believe the answer is:
lashes out
'spends big' is the definition.
(lash out can mean to spend a lot of money)
'capturing cricket trophy ruffian' is the wordplay.
'capturing' is an insertion indicator.
'cricket trophy' becomes 'ashes' (I've seen this before).
'ruffian' becomes 'lout' (I've seen this before).
'ashes' placed within 'lout' is 'LASHES OUT'.
(Other definitions for lashes out that I've seen before include "removing part of eye?" , "Hits wildly" .)
