The first of Kevin Cordes' two bids for a medal at the World Aquatics Championship ended with no hardware.
Australia's Christian Sprenger won the men's 100m breaststroke in 58.79, with Cameron Van Der Burgh of South Africa and Felipe Lima of Brazil taking silver and bronze in 58.97 and 59.65.
Cordes finished seventh in his first long-course World Championships, touching in 1:00.02.
"Getting ready in the ready room and being around a bunch of world-class swimmers and just racing them is what I'll take away," Cordes said. "I'm looking forward to doing it again. I felt like I had a decent stroke, and I'm just looking forward to having a shot at racing the 200."
Cordes will be competing in the 200m breast later this week.
Meanwhile, Tucson Ford Aquatics backstroker Matt Grevers qualified 1st for the final in the 100-meter event with a time of 52.97. The final is Tuesday night.
UA senior-to-be Kevin Steel swims Tuesday in the preliminary rounds of the 50-meter backstroke.
China leads the medal count with 18. The United States has won nine.
