Second-place finisher (6-2)
I believe the answer is:
runner-up
'second-place finisher' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for runner-up that I've seen before include "One nearly winning" , "One who is second in a race" , "One coming second" , "Silver medallist" , "Competitor who finishes second" .)
