The final day of artistic gymnastics helps pad team USA's medal count in Rio.

FOX's Chris Hoenig is covering the Olympics:

Before this summer, no American woman had ever won three gymnastics gold medals in a single Olympics...

Simone Biles has now won four. The U.S. star finishing atop the podium in the individual floor exercise finals. Aly Raisman, the silver medalist in the individual all-around behind Biles, also takes silver in the floor exercise.

Biles closing the Rio Games with four gold and one bronze, the most any American gymnast has won at one Games.

And it wasn't just the women, American Danell Leyva picking up silver in both the men's parallel bars and horizontal bar. The men's second and third gymnastics medals in Rio.
