Twenty years ago Nike aired an iconic ad featuring tennis greats Andre Agassi and Pete Sampras in a game of street tennis. This past week (just in time for the US Open) a few more tennis stars joined them for the twentieth anniversary of that ad for another game, and conveniently for us it happened to be right outside our office. There was Serena, Rafa, Maria, Kyrgios, Dimitrov, Madison Keys, Genie Bouchard, McEnroe (providing play-by-play and acting as chair umpire), and, of course, Protima's favorite, Federer.
