Cricketer takes that cap off and gets a derby (6,3)
I believe the answer is:
bowler hat
'a derby' is the definition.
(synonyms)
'cricketer takes that cap off' is the wordplay.
I cannot really see how this works, but
'cricketer' could be 'bowler' (bowler is a kind of cricketer) and 'bowler' is present in the answer.
'cap' could be 'hat' (cap can mean a hat) and 'hat' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and gets' is the link.
Can you help me to learn more?
(Other definitions for bowler hat that I've seen before include "Derby" , "Headgear of stiff felt" , "lid" , "One may have felt" , "traditional topping" .)
