Rob ended career (10)
I believe the answer is:
overcharge
'rob' is the definition.
(synonyms)
'ended career' is the wordplay.
'ended' becomes 'over' (synonyms).
'career' becomes 'charge' (both can mean to rush or run).
'over'+'charge'='OVERCHARGE'
(Other definitions for overcharge that I've seen before include "rook" , "Rip off" , "Ask too high a price" , "leave phone plugged in unduly long!" , "Demand too much money" .)
