The match at Los Angeles is the final (6)
I believe the answer is:
latest
'the final' is the definition.
(thesaurus)
'the match at los angeles' is the wordplay.
'the match' becomes 'test' (as in a test match in cricket).
'at' is a charade indicator (letters next to each other) (I've seen this in other clues).
'los angeles' becomes 'LA' (abbreviation).
'test' put after 'la' is 'LATEST'.
'is' acts as a link.
(Other definitions for latest that I've seen before include "Most recent or most unpunctual" , "Brand new, just out" , "In vogue" , "Most recent or tardiest" , "State-of-the-art" .)
