One throwing a jug (7)
I believe the answer is:
pitcher
This clue is a double definition.
'one throwing' is the first definition.
(I've seen this before)
'a jug' is the second definition.
(I've seen this before)
(Other definitions for pitcher that I've seen before include "that can hold his drink" , "Baseball bowler and container for liquid" , "Vessel with a handle and spout" , "Baseball player throws the vessel" , "Baseball player - bowl" .)
