[1] U.S. teenage sensation Missy Franklin blistered the field with a remarkable world record in textile to strike a backstroke double for the first time, since Romania's Diana Mocanu did so in 2000.

Dominating the race from the start, she threw down a sterling time of 2:04.06 to broaden a full-body length gap over the rest of the field and to slice three-quarters of a second (0.75) off the previous record set by Zimbabwe's Kirsty Coventry in a now-banned polyurethane bodysuit from the 2009 World Championships.

[2][3] Russia's Anastasia Zuyeva cleared a 2:06-barrier to take the silver in 2:05.92, while Franklin's teammate Elizabeth Beisel snatched the bronze in 2:06.55, handing over an entire medal haul for the Americans with a one-three finish.

[4][5] Backed by a raucous home crowd, Great Britain's Elizabeth Simmonds fell short of the podium with a fourth-place time in 2:07.26.

[6] Australia's Meagan Nay finished fifth in 2:07.43, while Coventry, a two-time Olympic champion, missed a chance to produce another historic three-peat as she claimed a distant sixth spot in 2:08.18.
