Seen in spring, a memorable match (4)
I believe the answer is:
game
'match' is the definition.
(thesaurus)
'seen in spring a memorable' is the wordplay.
'seen in' says the answer is hidden in the clue.
'GAME' is hidden in the letters of 'spring a memorable'.
(Other definitions for game that I've seen before include "Creatures hunted for sport" , "Final declaration of tennis result - . . . ., set and match" , "bet" , "eg Badminton" , "meat from hunting" .)
