A quick run-through of Michael Phelps’ day at the Rio Games from a statistical perspective:

Phelps’ two gold medals Tuesday gave him 21 golds overall including nine relay golds, both of which are Olympic records. His 14 individual medals -- 12 of which are gold -- tie Larisa Latynina, a gymnast from the Soviet Union, for the most all time.

At age 31, he’s the oldest individual gold medalist in Olympic swimming history.

His gold in the 200-meter butterfly was his third in the event. He previously won the 200 fly in 2004 and 2008. He’s the only male swimmer to win an individual Olympic event three times. He’s done so in the 100 butterfly, 200 butterfly and the 200 individual medley.

Phelps won the 200 butterfly Tuesday by 0.04 seconds over Masato Sakai of Japan, the closest margin in event history.

The win in the 200-meter freestyle relay was the United States’ fourth straight gold in the race. Phelps and Ryan Lochte became the first two swimmers to win four gold medals in the event.

Lochte passed Mark Spitz and Matt Biondi with his 12th Olympic medal, making him the second-most decorated male swimmer behind Phelps.

Phelps' 21 gold medals are 12 more than anyone else in Olympic history. Carl Lewis, Paavo Nurmi (a distance runner from Finland), Spitz and Latynina have nine each.
