Stanford grad Jason Dunford finished seventh in the 50 fly at the FINA World Championships in Shanghai, China on Monday.
Dunford, who recorded the fourth-best qualifying mark, went 23.60 in the event. Brazil's Cesar Cielo Filho won the title in 23.10.
Dunford swims for Kenya. There were no Americans in the final.
Elsewhere, American Dana Vollmer from Cal won the women's 100 fly in 56.87. Australia's Alicia Coutts was second in 56.94.
Vollmer gave the U.S. its first world title in the event since Stanford's Jenny Thompson won in 1998.
It is Vollmer's first individual world title, adding to her relay title in the 800 free relay from 2007.
"I feel so excited, I feel absolutely awesome," Vollmer told Swimming World. "I feel great, the arena is fantastic. I love being here, love representing the USA. Butterfly is my favorite especially 100 meters butterfly. Since I was young, we have done a lot of different things, like dance classes and other things. I think it's the combination that attracts me to the sport and perfects me in the water."
China's Shiwen Ye won the women's 200 IM in 2:08.90. Ariana Kukors finished third in 2:09.12 as the top American.
"I'm really happy and excited," Kukors told Swimming World. "Ye was incredible in the last 50 meters. I am incredibly happy, like I said yesterday, a couple of girls had the chance to win."
Norway's Alexander Dale Oen won the men's 100 breast in 58.71. The top American was Mark Gangloff in eight place with a time of 1:00.52.
It has been an emotional weekend for the Norwegian. With his home country in disarray following domestic terrorism attacks, Dale Oen put his focus on his work and stands fourth all time.
"We need to stay together now in Norway, and we just need to try to do the best we can," Dale Oen told Swimming World.
