Keep going to be the tenth man dismissed (4,3)
I believe the answer is:
last out
'keep going' is the definition.
(I've seen this before)
'the tenth man dismissed' is the wordplay.
'the tenth man' becomes 'last' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'dismissed' becomes 'out' (dismissed in cricket).
'last'+'out'='LAST OUT'
'to be' acts as a link.
Can you help me to learn more?
(Other definitions for last out that I've seen before include "Manage to survive" , "Survive for as long as is required" , "Keep on going" , "Endure" , "one leaving after everyone else" .)
