I believe the answer is:

establish

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

'put in place' is the definition.
'establish' can be an answer for 'place' (thesaurus). I am unsure of the 'put in' bit.

'this blase sort' is the wordplay.
'sort' indicates an anagram.
'this'+'blase'='thisblase'
'thisblase' is an anagram of 'ESTABLISH'.

Can you help me to learn more?

(Other definitions for establish that I've seen before include "Show to be true in his stable" , "Set up on permanent basis, or show to be true" , "Set up a business or prove to be true" , "Create - lodge" , "Found or authenticate" .)

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