Team get promotion after bagging runs (5)
I believe the answer is:
group
'team' is the definition.
(I know that team is a more specific form of the action group)
'get promotion after bagging runs' is the wordplay.
'get promotion' becomes 'go up' (eg go up a league in sport).
'after bagging' indicates putting letters inside.
'runs' becomes 'r' (cricket abbreviation).
'goup' placed around 'r' is 'GROUP'.
(Other definitions for group that I've seen before include "Assemble" , "Collective unit" , "Crew" , "Set; band" , "A number of elements with something in common (50" .)
