Court winner remains for hearing (4)
I believe the answer is:
ashe
'court winner' is the definition.
(tennis player Arthur Ashe)
'remains for hearing' is the wordplay.
'remains' becomes 'ash' (I've seen this before).
'for hearing' shows a homophone (sound like).
'ash' is a homophone of 'ASHE'.
(Other definitions for ashe that I've seen before include "US rallying champion" , "Former tennis star" , "US court star" , "Arthur, who came to court" , "tennis champ" .)
