Secure draw before winning (3,2)
I believe the answer is:
tie up
'secure' is the definition.
(thesaurus)
'draw before winning' is the wordplay.
'draw' becomes 'tie' ('tie' can be a synonym of 'draw').
'before' means one lot of letters go next to another.
'winning' becomes 'up' (I've seen this in other clues).
'tie'+'up'='TIE-UP'
(Other definitions for tie up that I've seen before include "Secure" , "Finish" , "draw at college" , "Tether" , "relationship?" .)
