Six deliveries bud and go too far (9)
I believe the answer is:
overshoot
'go too far' is the definition.
(I've seen this before)
'six deliveries bud' is the wordplay.
'six deliveries' becomes 'over' (cricket term).
'bud' becomes 'shoot' (I am not sure about this - if you are sure you should believe this answer much more).
'over'+'shoot'='OVERSHOOT'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for overshoot that I've seen before include "fail to stop where intended" , "Go past the mark" , "Go beyond the mark" , "Go too far" , "Go beyond the intended target" .)
