Bend down, getting no runs (4)
I believe the answer is:
duck
I believe this clue is a double definition.
'bend down' is the first definition.
'no runs' is the second definition.
(I've seen this before)
'getting' acts as a link.
(Other definitions for duck that I've seen before include "See 16" , "nothing" , "strong cloth" , "sails material" , "What represents zero score" .)
