Flattens the wicket? (5)
I believe the answer is:
rolls
'flattens' is the definition.
(rolling is a kind of flattening)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rolls that I've seen before include "Official lists" , "Small rounded breads" , "documents" , "Moves by turning" , "Baps - nice car" .)
