Slip costs Biles, Hernandez takes home silver in women's beam final in Rio

RIO DE JANEIRO[WATCH: BIG MOMENTS FOR TEAM USA]

The drive for five is over.

American Simone Biles was trying to become the first female gymnast to capture five gold medals at a single Olympics when she began the balance beam competition at the Rio Olympics on Monday. But she had to settle for bronze following a flawed performance, wobbling during the middle of her routine and landing awkwardly while completing a front somersault. Biles had to grab the beam with both hands to avoid falling down and eliminating herself from medal contention.

U.S. teammate Laurie Hernandez claimed the silver medal in an event won by Sanne Wevers of the Netherlands.

The 19-year-old Biles will be in the mix for another gold on Tuesday in the floor exercise finals.

Men's still rings

Eleftherios Petrounias of Greece has won the Olympic gold medal in men's still rings.

The reigning world champion put together a precise routine, finishing with a stuck dismount to post a score of 16.000. Arthur Zanetti of Brazil captured silver, delighting the home crowd inside Rio Olympic Arena. The crowd repeatedly shushed itself during Zanetti's set then exploded when his score of 15.766 flashed.

Denis Abliazin of Russia earned bronze

Men's vault

Se Gwang Ri of North Korea picked up his country's second gold medal in Rio, edging Denis Abliazin for gold in the men's vault final Monday.

Ri's two-vault average of 15.691 was better than Abliazin's average of 15.516. The medal for Abliazin was his second in less than an hour. He earned bronze on still rings earlier Monday afternoon.

Japan's Kenzo Shirai earned bronze in a tiebreaker over Romania's Marian Dragulescu. The two vaulters both averaged 15.449 for their two vaults, but Shirai was awarded the bronze because he had the highest score on a single vault.
