Easy chance (6)
I believe the answer is:
sitter
'easy chance' is the definition.
(as in a sitter in sport)
This is all the clue.
(Other definitions for sitter that I've seen before include "Artist's model or child's minder" , "Child-minder of sedentary disposition" , "Dolly" , "broody type" , "Sedentary baby minder?" .)
