American McKayla Maroney Wins Silver In Vault, Shocked By Sandra Izbasa

The gold medal finals in the individual gymnastics disciplines are underway on Sunday at the 2012 Olympic Games in London. There was a big upset in the finals for the women's vault, as United States gymnast McKayla Maroney -- who was a favorite in the event and ahead on points with one vault left to go -- fell on her second attempt and, as a result, ceded the gold medal to Sandra Raluca Izbasa of Romania.

Maroney stumbled on her landing and sat down, resulting in a huge loss of points, dropping her behind Izbasa and into second place, where she would have to settle for silver. It was a very rare flub for Maroney, who falls on landings so infrequently that longtime observers couldn't remember the last time it had happened.

Also of note was that Oksana Chusovitina -- who was a gold medalist in team gymnastics way back at Barcelona, in 1992 -- competed in the event. She is 37 and still going strong in her sixth Olympic games -- the first female gymnast to ever do so. She finished in fifth place in Sunday's vault.

Maria Paseka of Russia took home the bronze medal in the event.
