Mexico’s Paola Espinosa fell out of medal contention with her final dive here Thursday in the women’s 10-meter platform event at the 2012 London Olympics, finishing sixth.

Ruolin Chen of China took gold with a score of 422.30 points, followed by Australian Brittany Broben and Malaysia’s Pandelela Rinong Pamg.

After struggling in the qualifiers and the semifinals, the 26-year-old Mexican was much improved on Thursday and had the bronze medal in sight as she prepared for her fourth dive, but delivered a flawed performance.

Espinosa, a 2011 world champion who won the silver medal in women’s 10-meter synchronized diving with compatriot Alejandra Orozco on the fourth day of competition in London, is still looking for her first individual Olympic medal.
