Level in cup match, right? (4)
I believe the answer is:
tier
'level' is the definition.
(synonyms)
'cup match right?' is the wordplay.
'cup match' becomes 'tie'.
'right?' becomes 'R' (common abbreviation).
'tie'+'r'='TIER'
'in' acts as a link.
(Other definitions for tier that I've seen before include "One who secures" , "Rank - order" , "Level - layer" , "Row, level" , "'Level, grade (4)'" .)
