Superiors' bowling on the cricket ground (9)
I believe the answer is:
overlords
'superiors'' is the definition.
(I've seen this before)
'bowling on the cricket ground' is the wordplay.
'bowling' becomes 'over' (cricket term).
'on' means one lot of letters go next to another (in a down clue, letters appear on others).
'the cricket ground' becomes 'lords' (English cricket ground).
'over'+'lords'='OVERLORDS'
(Other definitions for overlords that I've seen before include "Most superior fellows" , "Superiors" .)
