Cup match level until just before the end (3)
I believe the answer is:
tie
'cup match' is the definition.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for tie that I've seen before include "Attach, fasten" , "Finish level" , "Draw - knot" , "Secure (with string)" , "'Fasten, with string say (3)'" .)
