Avoids low scores (5)
I believe the answer is:
ducks
This might be a double definition.
'avoids' is the first definition.
(duck can mean to avoid)
'low scores' is the second definition.
'ducks' can be an answer for 'scores' (duck is a kind of score). I am not certain of the 'low' bit.
Can you help me to learn more?
(Other definitions for ducks that I've seen before include "A bat skilfully avoids" , "Birds with webbed feet" , "Birds - term of endearment (informal)" , "My pet" , "Evades" .)
