Ours includes a cricket club, as it happens (6)
I believe the answer is:
occurs
'happens' is the definition.
('occur' can be a synonym of 'happen')
'ours includes a cricket club' is the wordplay.
'includes' is an insertion indicator.
'a cricket club' becomes 'cc' (cricketing abbreviation).
'ours' placed around 'cc' is 'OCCURS'.
'as it' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for occurs that I've seen before include "Crocus (anag)" , "Happens, takes place" , "Happens or comes to mind" , "Comes to pass" .)
