Labour's end pitch (8)
I believe the answer is:
delivery
This clue is a double definition.
'labour's end' is the first definition.
(as in delivering a baby)
'pitch' is the second definition.
(pitching a ball in cricket)
(Other definitions for delivery that I've seen before include "Act of giving birth" , "A handing over of goods" , "Process of giving birth" , "Rescue" , "Style of speaking" .)
