Crossword Genius

Does try badly to ruin (7)

Ross

I believe the answer is:

destroy

'ruin' is the definition.
('destroy' can be a synonym of 'ruin')

'does try badly' is the wordplay.
'badly' is an anagram indicator.
'does'+'try'='doestry'
'doestry' anagrammed gives 'DESTROY'.

'to' acts as a link.

(Other definitions for destroy that I've seen before include "put to death", "Annihilate", "Get rid of", "Flatten", "Demolish; pull down".)

I've seen this clue in Mirror.
