I have to agree with this. We "endured" sitting in the stands in some "good" seats at Miami one time watching both Sharapova and Azarenka in separate matches.
At least on the flat screen I can mute or turn down the volume, but I wonder if it is necessary or is an effect of learned gamesmanship? Cannot one expel air for explosive core effort without a shriek? Is it a physiological unavoidable fact for certain body types? I get an unavoidable grunt on some specific shots.
Shrieking on virtually every shot gets tiresome to me as a fan. If I had to play someone like that these days I would just walk off the court, bag my racket and go home. However, I do like laughter, praising opponents' good shots and some smack talk, probably not appropriate for pro game "focus" though
