Finished small batches of deliveries (5)
I believe the answer is:
overs
'batches of deliveries' is the definition.
'overs' can be an answer for 'deliveries' (cricket term). I am not certain of the 'batches of' bit.
'finished small' is the wordplay.
'finished' becomes 'over' (similar in meaning).
'small' becomes 's' (abbreviation - e.g. clothes size).
'over'+'s'='OVERS'
Can you help me to learn more?
(Other definitions for overs that I've seen before include "Periods of play" , "Lots of deliveries" , "Rounds of six bowls in cricket" , "Sets of six balls bowled" , "Divisions of a cricket match" .)
