Recreation managed by doctor (1,3,1)

Ross

I believe the answer is:

r and r

I'm a little stuck... Click here to teach me more about this clue!

'recreation' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see an association between them that I don't see?

'managed by doctor' is the wordplay.
'managed' becomes 'ran' (I've seen this before).
'by' is a charade indicator (letters next to each other).
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor').
'ran'+'dr'='R AND R'

Can you help me to learn more?

(Other definitions for r and r that I've seen before include "relaxation" , "A break from continuous service" .)
