Rafael Nadal is like the tennis version of Christopher Walken: Everybody has a good impression of him. (And he really cares about his watch.)
Andy Roddick, in particular, does a great Nadal, as he showed off Monday night during a New York exhibition against Roger Federer. The rolled-up sleeves, the grunting, the frenetic footwork, the upswinging groundstrokes behind the baseline; it was spot-on. The only negative: He didn't play left-handed.
