Rogue had to prepare a pitch (6)
I believe the answer is:
curate
'prepare a pitch' is the definition.
I can't judge whether this defines the answer.
'rogue had' is the wordplay.
'rogue' becomes 'cur' (both can mean a despicable person).
'had' becomes 'ate' (e.g. I had an ice cream).
'cur'+'ate'='CURATE'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for curate that I've seen before include "A truce for the church minister" , "Clergyman assisting a vicar" , "Assistant cleric" , "He didn't really want an egg" , "assistant rector" .)
