Overcome stout docker? Not entirely (5)

I believe the answer is:

outdo

'overcome' is the definition.
(outdoing is a kind of overcoming)

'stout docker? not entirely' is the wordplay.
'not entirely' indicates the answer is hidden within the clue.
'OUTDO' can be found hidden inside 'stout docker'.

(Other definitions for outdo that I've seen before include "going to top?" , "Beat" , "Go one beter than, surpass" , "Overtake" , "Surpass - overshadow - excel" .)

I've seen this clue in The Telegraph.
