Pod of Wimbledon favourite (4)
I believe the answer is:
seed
'wimbledon favourite' is the definition.
(tennis players are seeded)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for seed that I've seen before include "Plant reproducer" , "Pip; origin, beginning" , "Pip - source - children" , "- Pearl; - capital" , "who is ranked highly" .)
