Bend down, getting no score (4)
I believe the answer is:
duck
This clue is a triple definition!
'bend down' is the first definition.
'getting' acts as a link.
'no' is the second definition.
(duck means zero in cricket)
'score' is the third definition.
(duck is a kind of score)
(Other definitions for duck that I've seen before include "Evade - bird" , "sporting failure" , "Bob" , "Swimming bird" , "poor score?" .)
