The incomparable Michael Phelps lined up for the 200-meter butterfly final with a chance to win his 20th gold medal and if successful, become the oldest champion in individual swimming at the ripe old age of 31.

This is the first individual final of the Games for Phelps, who is competing in his fifth Olympics. The American in lane five led throughout the race with Chad le Clos on his right and Japan’s Masato Sakai close behind. Phelps touched the wall first with Sakai in second while Hungary’s Laszlo Cseh took the bronze.

And about half an hour after extending his record breaking medal total, Phelps was at it again, swimming the anchor leg of the 4 x 200-meter relay, as the Americans swam past the competition. Conor Dwyer, Townley Haas and Ryan Lochte shared this honor with the most decorated Olympian.

Chinese swimming sensation Ning Zetao had his work cut out for him in the semifinals of the men’s 100-meter freestyle. And the reigning world champion finshed in sixth place in his heat and 12th overall, which was not good enough to reach the final. Nathan Adrian of the USA had the fastest time.
