Nadull is playing better tennis in this 2nd set than he did during most of his career.
Nah, Rafa isn't actually very sharp today, leaking quite a lot cheap UEs that he usually wouldn't. Del Bonis just can't put him under any pressure. Looking at the draw, the only potentially interesting match Nadal could have here is vs Chardy. When 'on, Chardy's forehand is one of the biggest weapons in tennis, even if not at his best he would still test Rafa's movement and sharpness far more than anyone else in the draw.
