Run every single stretch (5)
I believe the answer is:
reach
'stretch' is the definition.
(I know that stretch can be written as reach)
'run every single' is the wordplay.
'run' becomes 'r' (cricket abbreviation).
'every single' becomes 'each' (I've seen this before).
'r'+'each'='REACH'
(Other definitions for reach that I've seen before include "Arrive at - stretch of river" , "Arrive at a point" , "Succeed in getting to" , "Arrive at, attain" , "Extent of influence" .)
