Take care of when ballboys need to give out balls? (8)
I believe the answer is:
preserve
'take care of' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for preserve that I've seen before include "Guard" , "Prevent from rotting" , "Maintain; keep safe" , "Maintain - jam" , "Keep from decay in perverse way" .)
