Displaying authority batting against time, runs over 50 (2,7)
I believe the answer is:
in control
'displaying authority' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'batting against time runs over 50' is the wordplay.
'batting' becomes 'in' (cricket term).
'against' becomes 'con' (as in pros and cons, for and against).
'time runs over' becomes 'tro' (this might be a standard abbreviation I've not previously seen).
'50' becomes 'l' (Roman numeral).
'in'+'con'+'tro'+'l'='IN CONTROL'
Can you help me to learn more?
(Another definition for in control that I've seen is " able to direct an activity".)
