Match points? (6)
I believe the answer is:
arenas
'match points?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for arenas that I've seen before include "Stadia" , "Central spaces of stadiums or amphitheatres" , "Spaces for sports events" , "Areas of endeavours" , "Level areas in centres of sport stadiums" .)
