The U.S. had been doing a good job of keeping with China lately and it seemed like after they took home four medals in track and field events that Team America would be in good shape to take the lead.
Unfortunately, the Chinese machine also took home big wins in women's team table tennis, and men's and women's gymnastics, and six other medals to stretch their medal lead to three.
The host country moved into third place (albeit with a tie in total medals, but they are ahead because apparently Russia doesn't believe in gold), but still a ways back on the U.S.A.
The big American win came in the 1,500-meter where Leo Manzano took a silver - the first time any American has medaled in this event in 44 years. Dawn Harper and Kellie Wells took home the silver and bronze, respectively, for the women's 100-meter hurdles, and Erik Kynard brought back silver for the men's high jump.
