Runs without running (6)
I believe the answer is:
extras
'runs' is the definition.
(cricket runs)
'without running' is the wordplay.
I cannot quite understand how this works, but
'without' could be 'ex' (Latin) and 'ex' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for extras that I've seen before include "Runs not scored from the bat" , "Crowd scene actors" , "Film actors in small non-speaking roles like crowd scenes" , "Additional items surplus to requirements, spares" , "minor players?" .)
