Get better of several deliveries with an edge, bagging 50 (9)
I believe the answer is:
overwhelm
'get better of' is the definition.
'several deliveries with an edge bagging 50' is the wordplay.
'several deliveries' becomes 'over' (set of cricket deliveries).
'with' is a charade indicator (letters next to each other).
'an edge bagging m0' becomes 'whelm' (I can't justify this - if you can you should believe this answer much more).
'over'+'whelm'='OVERWHELM'
(Other definitions for overwhelm that I've seen before include "Submerge" , "Conquer" , "Completely defeat" , "Overcome by superior force" , "Crush" .)
