Virtuoso and master playing ball (7)
I believe the answer is:
maestro
'virtuoso' is the definition.
(thesaurus)
'master playing ball' is the wordplay.
'playing' is an anagram indicator.
'ball' becomes 'o'.
'master' with letters rearranged gives 'maestr'.
'maestr'+'o'='MAESTRO'
'and' is the link.
(Other definitions for maestro that I've seen before include "Famous conductor" , "Eminent musician" , "Outstanding performer" , "Virtuoso" , "Top player" .)
