Whizz and spin round (3)
I believe the answer is:
pro
'whizz' is the definition.
(both can mean someone skilled at something)
'spin round' is the wordplay.
'spin' becomes 'PR' (short for public relations - media spin).
'round' becomes 'o' (round can mean a round object).
'pr'+'o'='PRO'
'and' acts as a link.
(Other definitions for pro that I've seen before include "With qualifications" , "For; non-amateur" , "Golfer" , "Of argument, say, in favour of" , "Paid worker" .)
