Roll pitch in the middle of batter's block (4)
I believe the answer is:
bunt
'roll' is the definition.
(thesaurus)
'pitch in the middle of batter's block' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
The remaining letters 'bun' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bunt that I've seen before include "Shot in baseball" , "hit with head" .)
