Brendan Hansen wins 100m breaststroke at US swimming trials

Hansen, 30, retired after the 2008 Beijing after failing to win an individual gold medal in two attempts in the Olympics.

But after winning in 59.68 seconds, said: "I am very proud of myself to adjust to it and work hard.

"I think I'll be very proud of me when I tell people I'm an Olympic athlete three times."

One night, after Ryan Lochte beat Michael Phelps in the 400m individual medley, who defeated his rival again in the semifinals of the 200m freestyle. The final is Wednesday.

Missy Franklin, 17, was the most important qualifier in the 100m Backstroke semifinals, recording a time of 59.06, which was less than a second behind world record Gemma Spofforth.

Natalie Coughlin, who won 11 medals in the last two Olympics, had a difficult night, but in this case. Coughlin barely qualified for the final with the seventh fastest time (1:00.63).

Matt Grevers stamped himself as a favorite in the 100 meters back to the top semifinal time of 53.10, and Olympic gold medalist Rebecca Soni led to the semifinals of the 100 breast (1:05.88).
