Jenny Thompson broke her own American record to win the 100 free final in 54.07. The second best time in the world this year, it broke her 54.27 mark set in July.
Dara Torres, who was also second to Thompson in the 100 fly, qualified for another Olympic event with a 54.62 second place. Torres, 33, will be the first woman to swim in four Olympic games.
Torres, who broke Thompson's American record in the prelims of the 100 fly, was out first at the 50 in 25.99, slightly ahead of Thompson's 26.03.
Ashley Tappin, 25 and swimming for Team Tyr, was third in 55.28.
Amy Van Dyken, who took four golds at the 1996 Olympics, was fourth in 55.30.
Courtney Shealy was fifth in 55.52, and Erin Phenix was sixth in 55.61.
15-year-old Christina Swindle was seventh in 55.77, and Liesl Kolbisen was eighth in 56.05.
The top six qualifiers make the Olympic team for the 400 free relay.
Tappin, Thompson and Torres were all teammates on the 1992 Olympic gold 400 free relay. (Thompson, 27, and Torres also both swim for Stanford.)
And Van Dyken, 27, and Thompson also won golds on the 400 free relay in 1996.
"I'm just putting it all on the line here," said Thompson. "This will probably be my last go, so I want to make sure I'm doing everything right and covering all my bases."
