Finished some deliveries (4)
I believe the answer is:
over
This clue is a double definition.
'finished' is the first definition.
(over can mean finished or ended)
'some deliveries' is the second definition.
(a cricket over consists of six deliveries)
(Other definitions for over that I've seen before include "In the sky?" , "See 19" , "Finished like cricket period" , "Bout of six bowls in cricket" , "Exceeding - finished" .)
