Fielder – one of daddy's six? (4,3)
I believe the answer is:
long leg
'fielder' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for long leg that I've seen before include "Cricket fielder - one of four on a giraffe?" , "cricketer's position?" , "Crane fly has more than one" , "A feature of one seen to be tall" , "who fields in the deep?" .)
