Soni breaks own WR to win 200 breast

American Rebecca Soni was the first swimmer to defend their Olympic title in London, breaking her own world record in the women's 200-meter breaststroke Thursday night

Soni broke the world record she set in the semifinals Wednesday night by just .41 seconds, touching the wall in 2 minutes, 19.59 seconds.

"It means the world to me that I can be the first one under 2:20," said Soni, who won silver in the 200 breast this week.

Japan's Satomi Suzuki was second and Russia's Iuliia Efimova won bronze. American Micah Lawrence finished sixth.
