I like Rafa, but something caught my attention during the USO that made me wonder a bit. In the Medvedev match it seemed that when hitting the ball his grunts were prolonged to the point that he was still making noise as Medvedev was about to hit the ball. However, when he played his friend and practice buddy Schwartzman, his grunts were shorter and thus less of a potential hindrance to his opponent. DId this happen, and could it have been conscious or unconscious gamesmanship? Was it just too much Asahi Dry Black?
