Crossword Genius

Outer sort of course (5)

Ross

I believe the answer is:

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

'outer sort' is the wordplay.
'sort' indicates an anagram.
'outer' is an anagram of 'ROUTE'.

'of' acts as a link.

(Other definitions for route that I've seen before include "Course taken", "The way to get somewhere", "Send a particular way", "Course followed", "Way, course".)

I've seen this clue in Mirror.
