Some high scores ultimately bring outcome (6)
I believe the answer is:
result
'outcome' is the definition.
(I know that outcome can be written as result)
'some high scores ultimately' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'RESULT' is hidden within 'high scores ultimately'.
'bring' acts as a link.
(Other definitions for result that I've seen before include "'Outcome, consequence (6)'" , "Ulster (anag) - outcome" , "Outcome of an undertaking" , "'Outcome, upshot (6)'" , "End - issue" .)
