Canadian Annamay Pierse is the fastest female 200-metre breaststroke swimmer in the world no longer after Rebecca Soni lowered her record by 0.12 seconds in Wednesday's Olympic semi-finals.
Soni swam a world-best time of two minutes, 20.00 seconds to advance into Thursday's medal race.
"I felt there was no pressure. I just wanted to feel it and see how it went," Soni said. "I just went for it. You'll see that records are becoming faster worldwide and it's going to be great."
Martha McCabe of Toronto, Ont., also advanced. The Canadian swimmer trains under the same coach as Pierse, and is the reigning World bronze medallist.
She finished seventh overall in the semis, completing her race in 2:24.09 seconds -- 0.72 seconds faster than her bronze-medal swim at last year's world championships. She was still not satisfied.
"I just needed to get through the final and I did that. I need to be a lot faster tomorrow night," the 23-year-old said. "I know it's in me, it's just a matter of getting it out."
