After a particularly brutal day at the U.S. Open on Saturday, 10 American men and women still remain in the Round of 16. That is the most at any major since 11 (four men, seven women) at the 2002 U.S.
After another wildly unpredictable start to a major, the second week of the US Open is upon us. And there are 10 Americans left in the draw.
