The United States continues their dominance in the pool at the Rio Games.

FOX's Chris Hoenig has more from Olympic Park:

Michael Phelps broke out in a wide smile when he heard his Maryland friends at the Olympic Aquatics Stadium shout the "Oh" during the Star Spangled Banner, a tradition at Orioles games.

Of course, he had plenty of reason to smile after picking up two more Gold medals in Men's 200-meter Butterfly, where he avenged his loss four years ago in London, as well as the 4-by-200 Freestyle Relay. That gives him 21 career Gold medals, 24 overall Olympic medals.

Katie Ledecky also picked up her second Gold of the Games, the Women's 200-meter Freestyle. She's 2/3's of the way to becoming the first woman to sweep the 200-, 400- and 800-meter Freestyles since 1968.

Team USA also adding a Bronze medal. Maya DiRado getting that in the Women's 200-meter Individual Medley...
