Rope's end pulled back arresting a run (6)
I believe the answer is:
lariat
'rope's' is the definition.
(lariat is a kind of rope)
'end pulled back arresting a run' is the wordplay.
'end' becomes 'tail' (tail is a kind of end).
'pulled back' is a reversal indicator.
'arresting' is an insertion indicator.
'run' becomes 'r' (cricket abbreviation).
'tail' written backwards gives 'liat'.
'a'+'r'='ar'
'liat' enclosing 'ar' is 'LARIAT'.
(Other definitions for lariat that I've seen before include "Rope for the cowboy" , "A cowboy's rope with noose" , "Long noosed rope for catching animals" , "A cowboy's working rope" , "Rope to lasso or tether" .)
