Germany's Britta Steffen blasted a new Olympic record to claim a gold medal in the event. Coming from eighth place in the turn, she posted a time of 53.12 to edge out Australia's world record holder and top favorite Lisbeth Trickett by 0.04 of a second. Swimming in lane eight, Trickett earned a silver with an outside record time of 53.16.[2][3][4] She narrowly reached the final as the eighth seed, when China's Pang Jiaying was disqualified for a false start in the semifinals.[5] Meanwhile, U.S. swimmer Natalie Coughlin powered home with a bronze in a matching American record of 53.39 for the second consecutive Olympics. It was Coughlin's fifth medal of these Games, matching her total from Athens four years earlier.[6]

Earlier, she posted a top-seeded time of 53.60 from the sixth heat to lead the prelims.[7] She was followed in fifth place by Denmark's Jeanette Ottesen (54.06), and host nation China's Zhu Yingwen, who shared a sixth-place tie with the Netherlands' Marleen Veldhuis in 54.21.
