Put away some headers to win (4)
I believe the answer is:
stow
'put away' is the definition.
(thesaurus)
'some headers to win' is the wordplay.
'headers' says to take the initial letters (I've seen 'header' mean this (in a down clue, the letter at the top of the word)).
'win' becomes 'w' (abbreviation in sport).
The initial letter of 'some' is 's'.
's'+'to'+'w'='STOW'
(Other definitions for stow that I've seen before include "Pack tightly" , "Fill by packing tightly" , "Pack or store carefully, luggage perhaps" , "Lay up, pack away" , "Deposit" .)
