Home run, in sports slang (5)
I believe the answer is:
tater
'home run in sports slang' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tater that I've seen before include "King Edward, for example" , "Champ is mostly" , "Potato (informal)" , "Murphy" , "Charlotte, for example" .)
