Score with Ulster thrashed (6)
I believe the answer is:
result
'score' is the definition.
(I've seen this before)
'ulster thrashed' is the wordplay.
'ulster' can be anagrammed to 'RESULT'.
Though, I'm not clear how the anagram is indicated.
'with' is the link.
Can you help me to learn more?
(Other definitions for result that I've seen before include "End - issue" , "'Outcome, consequence (6)'" , "'Outcome, upshot (6)'" , "Final outcome" , "Effect - outcome" .)
