Famous cricketer, wicked guy bagging runs (7)
I believe the answer is:
bradman
'famous cricketer' is the definition.
(Don Bradman, 1908-2001)
'wicked guy bagging runs' is the wordplay.
'wicked' becomes 'bad' (similar in meaning).
'guy' becomes 'man' (guy can informally mean a man).
'bagging' means one lot of letters goes inside another (I've seen this in other clues).
'runs' becomes 'r' (cricket abbreviation).
'bad'+'man'='badman'
'badman' enclosing 'r' is 'BRADMAN'.
(Other definitions for bradman that I've seen before include "Sir Donald -, Australian test cricketer" , "Don -, Aus. Test cricketer" , "Don -, Austr. cricketer" , "Batsman" , "Sporting legend" .)
