The hard courts of USTA Billie Jean King National Tennis Center in Queens, N.Y., is the setting for the next two weeks as the game's top players go at it in the year's final Grand Slam event, the U.S. Open. On the men's side, three players with 20 Slams under their belts — Roger Federer, Rafael Nadal and Novak Djokovic — will be going for career No. 21, an all-time record. On the women's side, it could be a wide-open field with defending champ Naomi Osaka's status in question and Serena Williams coming off injury.
