Was responsible for six deliveries - was wrong (7)
I believe the answer is:
oversaw
'was responsible' is the definition.
I can't tell whether this defines the answer.
'six deliveries was wrong' is the wordplay.
'six deliveries' becomes 'over' (a cricket over consists of six deliveries).
'wrong' is an anagram indicator.
'was' with letters rearranged gives 'saw'.
'over'+'saw'='OVERSAW'
'for' is the link.
Can you help me to learn more?
(Other definitions for oversaw that I've seen before include "watcher" , "Managed" , "What supervisor did" , "Supervised" .)
