One baseballer in the jug? (7)
I believe the answer is:
pitcher
'the jug?' is the definition.
(I've seen this before)
'one baseballer' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'er' (I've seen this in other clues) and 'er' is found within the answer.
The remaining letters 'pitch' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for pitcher that I've seen before include "One throwing" , "able to hold a lot of beer" , "Ewer" , "Vessel with a handle and spout" , "one getting walked all over?" .)
