Imitating Oscar performance provides some relief (10)

I believe the answer is:

mitigation

'some relief' is the definition.
(thesaurus)

'imitating oscar performance' is the wordplay.
'oscar' becomes 'O' (phonetic alphabet: alpha, bravo, charlie etc.).
'performance' indicates an anagram.
'imitating'+'o'='imitatingo'
'imitatingo' anagrammed gives 'MITIGATION'.

'provides' acts as a link.

(Another definition for mitigation that I've seen is " Plea for mercy".)

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