LONDON -- Ranomi Kromowidjojo of the Netherlands set an Olympic record to lead the women's 100-meter freestyle semifinals Wednesday, while defending champion Britta Steffen of Germany failed to advance.
Kromowidjojo was timed in 53.05 seconds, 0.07 faster than Steffen's swim at the 2008 Beijing Games in a now-banned bodysuit.
Melanie Schlanger of Australia qualified second in 53.38 and American teenager Missy Franklin was third in 53.59.
Steffen was only 12th.
The top eight finishers qualified for Thursday's final in swimming's signature event.
