Delivery of drink around morning (6)
I believe the answer is:
beamer
'delivery' is the definition.
(type of cricket delivery)
'drink around morning' is the wordplay.
'drink' becomes 'beer' (beer is a kind of drink).
'around' means one lot of letters goes inside another.
'morning' becomes 'am' (as in 12:00 AM).
'beer' going around 'am' is 'BEAMER'.
'of' acts as a link.
(Other definitions for beamer that I've seen before include "Fast, high delivery (cricket)" , "ball flying past ear?" , "ball bowled at head" , "One smiling" , "wayward delivery" .)
