'whitewash' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'trophy has finished' is the wordplay.
'trophy' becomes 'cup' (cup is a kind of trophy).
'has' is an insertion indicator.
'finished' becomes 'over' (over can mean finished or ended).
'cup' enclosing 'over' is 'COVERUP'.

'in' acts as a link.
