Lid of trophy turned up (3)
I believe the answer is:
top
'lid' is the definition.
(eg a bottle top)
'trophy turned up' is the wordplay.
'trophy' becomes 'pot' (type of trophy).
'turned up' is a reversal indicator.
'pot' backwards is 'TOP'.
'of' acts as a link.
(Other definitions for top that I've seen before include "Finest" , "Peak; beat" , "cap and > sweater" , "Better" , "Children's toy" .)
