Way to get out member sooner (3,6)
I believe the answer is:
leg before
'way to get out' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'member sooner' is the wordplay.
'member' becomes 'leg' (member can mean a limb).
'sooner' becomes 'before' (I can't explain this - if you can you should believe this answer much more).
'leg'+'before'='LEG BEFORE'
Can you help me to learn more?
(Another definition for leg before that I've seen is " Way of being out at cricket".)
