Runs in to adore stirring bullfighter (8)
I believe the answer is:
toreador
'bullfighter' is the definition.
(I know that bullfighter is a type of bullfighter)
'runs in to adore stirring' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'in' means one lot of letters goes inside another.
'stirring' is an anagram indicator.
'to'+'adore'='toadore'
'toadore' is an anagram of 'toeador'.
'r' inserted inside 'toeador' is 'TOREADOR'.
(Other definitions for toreador that I've seen before include "Man honoured to be given an ear" , "Bullfighter in Carmen" , "One who fights bulls" , "Mounted bullfighter" , "killer on mount" .)
