Brendan Hansen swims in the 200 breaststroke finals at Thursday's Olympic Trials in Omaha, Neb. Hansen placed fourth and, in a stunner, didn't qualify for the 2008 Olympic Games in the event.

Oklahoma City ? Brendan Hansen won’t be swimming one of his signature events at the Beijing Olympics.

In the first major stunner of the U.S. swimming trials, Hansen failed to make the Olympic team in the 200-meter breaststroke Thursday. The world recordholder less than a month ago was knocked out by a fourth-place showing.

Hansen’s only solace: He still has a spot in the 100 breast and, most likely, the 400 medley relay.

“I gave everything in the pool tonight. I left it all out there. It just wasn’t there. It wasn’t my day,” he said.

Scott Spann – a Hansen training partner – powered to the biggest win of his career in 2:09.97. Eric Shanteau, who also trains with Hansen, was second in 2:10.36. Scott Usher was timed in 2:11.0 and Hansen 2:11.37. Katie Hoff, who already had qualified for four individual events and one relay, failed to advance out of the semifinals of the 100 freestyle.
