Cricket side succeeded, showing staying power? (4)
I believe the answer is:
legs
'staying power?' is the definition.
(if something 'has legs' it has staying power)
'cricket side succeeded' is the wordplay.
'cricket side' becomes 'leg' (I've seen this before**).
'succeeded' becomes 's' (genealogical abbreviation).
'leg'+'s'='LEGS'
'showing' acts as a link.
(Other definitions for legs that I've seen before include "Members" , "Stages of a journey" , "associated with 11 in game" , "Lower limbs" , "Sections of a journey or course" .)
