Biles wins 4th Rio Games gold in floor exercise

American Simone Biles competes in the balance beam at the Rio Summer Olympics.

RIO DE JANEIRO (AP) Simone Biles put the finishing touches on one of the greatest Olympics by a gymnast ever, capturing her fourth gold of the games with a showstopping performance in the floor exercise.

The 19-year-old American on Tuesday completed an extraordinary stretch that included a team gold for the "Final Five" as well as individual golds in the all-around and vault and bronze on balance beam.

Her five medals tie the most for an American woman in a single Olympics and her four golds tie an Olympic record shared by three others.

Biles embraced longtime coach Aimee Boorman shortly after her routine, which includes a tumbling pass named in her honor and a Brazilian-themed segment intended to play to the crowd in Rio. She beamed when her score of 15.966 was posted.

Teammate Aly Raisman followed with a 15.500 silver-medal performance to give her a third medal during Rio and six overall in her Olympic career.
