Bowls and fields around mid-morning? (6)
I believe the answer is:
arenas
'bowls' is the definition.
(bowl can mean a sports stadium)
'fields around mid-morning?' is the wordplay.
'fields' becomes 'areas' ('area' can be a synonym of 'field').
'around' indicates putting letters inside.
'mid' indicates the central letters.
The central letter of 'morning' is 'n'.
'areas' enclosing 'n' is 'ARENAS'.
'and' is the link.
(Other definitions for arenas that I've seen before include "Structures for open-air events" , "Central areas of, say, sports stadiums" , "Places of sports contests" , "Level areas in centres of sport stadiums" , "Areas in centre of amphitheatres" .)
