FEDERAL WAY — Troy Dumais and Kristian Ipsen took control over the last two rounds and built a 27.33-point lead in the 3-meter synchro at the U.S. Olympic diving trials on Monday night.

Dumais is trying to join Greg Louganis as the only American man to make four Olympic teams. He and Ipsen totaled 876.00 points through the preliminaries and semifinals to advance to Friday's final.

"We know how to finish the dive off," said Dumais, who was diagnosed with strep throat a week ago.

The 32-year-old Dumais has won medals at world championships, Pan American Games, World Cups and national championships, but never at the Olympics, where his highest finish was sixth.

Chris Colwill, a 2008 Olympian, and Drew Livingston were second at 849.33 after edging Dumais and Ipsen in the prelims.

"Drew and Chris looked the best I've ever seen them," Ipsen said. "We had a wake-up call in the first round."

David Bonuchi and Michael Hixon were third at 779.28.

Justin and Dwight Dumais were chasing their brother, Troy, and were in fourth.

The top eight teams advanced to the final, where only the first-place team earns an Olympic berth.
