On one side of an outfield pole

I believe the answer is:

foul

(Other definitions for foul that I've seen before include "Loathsome - tackle breaking game rules" , "Abominable - offence on football field" , "Unfair, against rules of game" , "Break the rules on the pitch" , "Having offensive smell or taste" .)

I've seen this clue in The New York Times.
