To push for an outcome (6)

I believe the answer is:

upshot

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

'an outcome' is the definition.
(synonyms)

'to push' is the wordplay.
'to push' anagrams to 'UPSHOT'.
But, I am not clear how the anagram is indicated.

'for' is the link.

Can you help me to learn more?

(Other definitions for upshot that I've seen before include "anti-aircraft fire?" , "skier" , "One killed the albatross" , "increased exposure" , "Outcome, final result" .)

I've seen this clue in the Evening Standard.
