OMAHA, Neb. (AP) - Brendan Hansen was done with swimming after two doses of Olympic heartache.

He's feeling a lot better now.

Next stop: London.

Hansen, who retired from the sport after the Beijing Games but couldn't stay away, made his comeback worthwhile by winning the 100-meter breaststroke at the U.S. Olympic trials Tuesday night.

He celebrated during the victory ceremony by kneeling down like a pro wrestler and giving the "hook 'em horns" sign - a nod to his Texas home and training base - as the podium slowly lifted him from beneath the pool deck into full view of more than 12,000 fans.

"No one would ever expect me to do something like that," Hansen said. "I'm not a flashy guy. I don't have grillz in my mouth (like Ryan Lochte). I don't have eight gold medals (like Michael Phelps)."

Dana Vollmer, a gold medalist as a teenager in 2004, missed out on the team four years ago while battling injuries and health problems. It's all good now. She got off to a blistering start and soared through the water to easily win the 100 butterfly.

And, oh yeah, there was another memorable race between Lochte and Phelps, but there's a bigger showdown to come. One night after Lochte beat Phelps in the 400 individual medley, Lochte edged him out again in the semifinals of the 200 freestyle.

That's just a tuneup for tonight's final, which figures to be another classic between the world's two greatest swimmers.

"Oh, that was the semifinals. It doesn't really matter," Lochte said. "It doesn't matter until the finals. We're great racers, we just want to win. We definitely kicked it in gear the last 50, me and him. We know tomorrow night is going to be a lot faster."

Natalie Coughlin, who won gold in the 100 back at the past two Olympics, had a rough night. After coming up short in the 100 fly, she barely qualified for the final of her signature event with the seventh-fastest time (1:00.63). She's looking to get to London so she can take a shot at Jenny Thompson's record for most decorated American female swimmer, having won 11 medals at the past two Olympics.
