mixed doubles

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

'pairs game coming as' is the definition.
I can't tell whether this defines the answer.

'result of unusually bold use?' is the wordplay.
'result of' becomes 'mixed' (I can't justify this - if you can you should give a lot more credence to this answer).
'unusually' is an anagram indicator.
'bold'+'use'='bolduse'
'bolduse' with letters rearranged gives 'doubles'.
'mixed'+'doubles'='MIXED DOUBLES'

Can you help me to learn more?

(Other definitions for mixed doubles that I've seen before include "Tennis for ladies and gents" , "Woman/man v woman/man at tennis" , "Tennis competition" , "His 'n' hers tennis" , "shorts?" .)

I've seen this clue in The Telegraph.
