LONDON - Rebecca Soni lowered her own world record in winning the gold medal in the 200-meter breaststroke Thursday at the London Olympics.
She won in 2:19.59, taking .01 seconds off the record she set one night earlier.
Soni led from wire to wire, opening up a 1.13-second gap over silver medalist Satomi Suzuki of Japan. The bronze medal was won by Russia's Iuliia Efimova.
The 200 back is Soni's best and favorite event. She won it in Beijing in 2008, beating then-world champion and world record holder Liesel Jones of Australia.
Soni broke the world record during Wednesday night's semifinal, swimming the 200 back in 2:20.00, proving it's possible to go that fast even without the fast bodysuits from years past.
Soni's gold is her second medal of these Games. She won silver in the 100-meter breaststroke earlier in the week.
She is also expected to participate in the women's 4x100-meter medley relay on Saturday.
