Find fault with Joe Root's innings? (5)

I believe the answer is:
knock
This clue might be a double definition.
'find fault with' is the first definition.
(I've seen this in another clue)
'innings?' is the second definition.
(I've seen this in other clues)
'joe root's' is the link.
I am not very happy about this link. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for knock that I've seen before include "Sharp blow, perhaps on door" , "Bang" , "Find fault with" , "Strike; setback" , "Fail to hit" .)
