Stadium whistle-blower (3)

Ross

I believe the answer is:

ref

(Other definitions for ref that I've seen before include "One traditionally in black" , "Sports umpire" , "A diminutive umpire in soccer or boxing" , "'Game judge, in short (3)'" , "Middleman needing cards" .)

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