The United States has finally overtaken China in both total medals and gold medals, following a very winning Friday of competition that included one last gold medal win for Michael Phelps, who now has 17 all-time. In the total medal count, the U.S. now has 43 against China's 42. On the gold medal front, America now has 21 gold medals, while China is sitting at 20.

The two countries are far outpacing the rest of the field, as the next closest country is Russia, with 23 total medals, although just three gold. Making significant strides over the last few days are host country Great Britain, who are in third place with 22 medals.

Here are the top five countries heading into Saturday:

1. United States - 43 (21, 10, 12)
2. China - 42 (20, 13, 9)
3. Russia - 23 (3, 12, 8)
4. Great Britain - 22 (8, 6, 8)
