Caught balls in lid (5)
I believe the answer is:
cover
'lid' is the definition.
(I've seen this before)
'caught balls' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'balls' becomes 'over' (I've seen this in other clues).
'c'+'over'='COVER'
'in' acts as a link.
(Other definitions for cover that I've seen before include "Sit on - suffice for" , "Conceal a thing or fact - . . . . . up" , "Disguise" , "(Put) lid (on) - fielding position - insurance" , "Lid, travel (distance)" .)
