Stirred large drinks for Wimbledon match (5,7)
I believe the answer is:
mixed doubles
'wimbledon match' is the definition.
(type of tennis played at Wimbledon)
'stirred large drinks' is the wordplay.
'stirred' becomes 'mixed'.
'large drinks' becomes 'doubles' (a double is a large alcoholic drink).
'mixed'+'doubles'='MIXED DOUBLES'
'for' is the link.
(Other definitions for mixed doubles that I've seen before include "Woman/man v woman/man at tennis" , "His 'n' hers tennis" , "tennis match?" , "shorts?" , "Tennis competition" .)
