Sluggishness of shattered troop on run (6)
I believe the answer is:
torpor
'sluggishness' is the definition.
(I've seen this in another clue)
'shattered troop on run' is the wordplay.
'shattered' indicates an anagram.
'on' indicates putting letters inside (as in clothing 'on' a person).
'run' becomes 'r' (cricket abbreviation).
'troop' is an anagram of 'topor'.
'topor' enclosing 'r' is 'TORPOR'.
'of' is the link.
(Other definitions for torpor that I've seen before include "Inactivity, lassitude" , "State of dullness" , "State of lethargy or sluggishness" , "lack of energy" , "Listlessness" .)
