Legendary bowler - one might fall for a duck (5)
I believe the answer is:
drake
'legendary bowler' is the definition.
'drake' can be an answer for 'bowler' (I've seen this before). I'm not sure about the 'legendary' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for drake that I've seen before include "Elizabethan sailor" , "English circumnavigator, d. 1596" , "Nick" , "Sir Francis - -" , "Male bird" .)
