Greater rod debacle going back (10)

I believe the answer is:

retrograde

I'm a little stuck... Click here to teach me more about this clue!

'going back' is the definition.
(I've seen this before)

'greater rod debacle' is the wordplay.
'greater rod' anagrams to 'RETROGRADE'.
Though, I am not sure how the anagram is indicated.

Can you help me to learn more?

(Other definitions for retrograde that I've seen before include "inverse" , "Backward" , "Declining" , "Reverse" , "Going back" .)

I've seen this clue in the Sydney Morning Herald.
