Attack American woman on team (9)
I believe the answer is:
broadside
'attack' is the definition.
(broadside is a kind of attack)
'american woman on team' is the wordplay.
'american woman' becomes 'broad'.
'on' is a charade indicator (letters next to each other).
'team' becomes 'side' (both can mean a sports team).
'broad'+'side'='BROADSIDE'
(Other definitions for broadside that I've seen before include "Strongly critical verbal attack" , "A strong attack in words - or by old ship" , "barrage" , "Fierce verbal attack" , "Stick" .)
