Such a rascal can’t be a good bowler (3,3)

I believe the answer is:

bad hat

I'm a little stuck... Click here to teach me more about this clue!

'such a rascal can't' is the definition.
I can't judge whether this defines the answer.

'a good bowler' is the wordplay.
'a good' becomes 'bad' (I can't explain this - if you can you should believe this answer much more).
'bowler' becomes 'hat' (I've seen this in other clues).
'bad'+'hat'='BAD HAT'

'be' is the link.

Can you help me to learn more?

I've seen this clue in the Evening Standard.
