Speak over judge (5)
I believe the answer is:
orate
'speak' is the definition.
(I know that orate is a more specific form of the action speak)
'over judge' is the wordplay.
'over' becomes 'o' (cricket abbreviation).
'judge' becomes 'rate' (rating is a kind of judging).
'o'+'rate'='ORATE'
(Other definitions for orate that I've seen before include "Talk pompously" , "Speak in florid style" , "Lecture" , "Make a pompous speech" , "Speaker may" .)
