Matt Grevers turned in the second-best time in history in the 100m backstroke, as he and Nick Thoman qualified for the American team in London.

The world record is held by Aaron Peirsol, who took gold in 2008 while Grevers took second. With Peirsol retired from competition, there were two slots open for the U.S. contingent in the event. Grevers was clearly setting quite a pace through the first 50 meters, hitting the turn just .02 seconds behind the world-record split. He kept up the dominant pace and was half a body length clear of the field at the touch.

The race for second was more intriguing, as a number of swimmers were in a pack heading towards the final wall. A strong push down the end from Thoman allowed him to touch second and book a spot in London.

Here are the full results from the event:

1. Matt Grevers: 52.08
   
2. Nick Thoman: 52.86
   
3. David Plummer: 52.98
