One's tossed kind of red net away (5)
I believe the answer is:
caber
'one's tossed' is the definition.
(as in caber-tossing)
'kind of red net away' is the wordplay.
'kind of red' becomes 'cabernet' (kind of red wine).
'away' indicates named letters should be taken away.
'cabernet' with 'net' removed is 'CABER'.
(Other definitions for caber that I've seen before include "Trunk tossed in the Highlands" , "requirement for Highland fling?" , "Pole tossed in Highland games" , "One Highlanders toss" , "Something tossed in the Highlands" .)
