Devastating winger hit shot (9)
I believe the answer is:
withering
'devastating' is the definition.
('withering' can be a synonym of 'devastating')
'winger hit shot' is the wordplay.
'shot' indicates anagramming the letters.
'winger'+'hit'='wingerhit'
'wingerhit' anagrammed gives 'WITHERING'.
(Other definitions for withering that I've seen before include "Supercilious" , "Devastating" .)
