Wrestling team maniac hit stats analyst (13)
I believe the answer is:
mathematician
'stats analyst' is the definition.
I can't judge whether this defines the answer.
'wrestling team maniac hit' is the wordplay.
'wrestling' is an anagram indicator.
'team'+'maniac'+'hit'='teammaniachit'
'teammaniachit' anagrammed gives 'MATHEMATICIAN'.
Can you help me to learn more?
(Other definitions for mathematician that I've seen before include "Studier of organisms and their surroundings" , "Number specialist" , "Eg, Leonhard Euler" , "Dealer in numbers" , "Euclid, say" .)
