A female's sporting trophy? (5)

I believe the answer is:

ashes

'sporting trophy?' is the definition.
(I've seen this before)

'a female's' is the wordplay.
'female's' becomes 'she's' ('she' refers to a woman).
'a'+'shes'='ASHES'

(Other definitions for ashes that I've seen before include "Powders remaining after fire" , "Burnt residue" , "Remains of the Yule logs?" , "Residue from fire" , "sporting trophy" .)

I've seen this clue in the Evening Standard.
