Clog (old) deliberately ruined (9)

I believe the answer is:

sabotaged

'deliberately ruined' is the definition.

'clog old' is the wordplay.
'clog' becomes 'sabot' (both can mean a type of shoe).
'old' becomes 'aged' (similar in meaning).
'sabot'+'aged'='SABOTAGED'

(Other definitions for sabotaged that I've seen before include "Damaged" , "deliberately wrecked" , "crippled" , "Incapacitated" , "Deliberately destroyed (equipment, plans, etc)" .)

I've seen this clue in The Guardian.
