Simone Biles Soars to Fourth Gold Medal

For anyone who doubted her after a subpar performance on the balance beam, Simone Biles sent an emphatic message on Tuesday: She is unbeatable in the floor exercise.

Biles bounced back from a bronze medal performance on the beam to dominate the floor, completing her Rio Olympics with four gold medals and the bronze. She is the fourth American female gymnast to win five medals in a single Olympics, joining Mary Lou Retton (1984), Shannon Miller (1992) and Nastia Liukin (2008). Biles scored a 15.966 in the floor, considered her best event.

Her signature floor move is the Biles, a double layout with a half-twist and a blind landing. She performed the move nearly perfectly, adding a stag leap, which she had left out of her performance in the team event but included in the individual all-around.

Her score dwarfed those of her competitors. Her teammate Aly Raisman won the silver medal with a routine slightly less difficult than Biles’s, sticking every landing on every tumbling pass. The bronze medal went to Amy Tinkler, the first female gymnast from Britain to compete in a floor final.

Raisman earned her sixth Olympic medal and her third at these Games. She won the team gold and the silver in the individual all-around, behind Biles, who also won the vault.

Tuesday’s victory put Biles in an exclusive club. Just three female gymnasts before her — Ecaterina Szabo of Romania (1984), Vera Caslavska of Czechoslovakia (1968) and Larisa Latynina of the Soviet Union (1956) — had also won four gold medals in one Olympics.

Also Tuesday, the American Danell Leyva won silver medals in the parallel bars and the horizontal bar. Leyva, 24, was the bronze medalist in the all-around at the 2012 London Games, but was not initially selected for the United States team. An alternate, Leyva was added to the team when John Orozco tore the anterior cruciate ligament in his left knee during Olympic training in July.
