Thompson, the world record-holder in the 100 freestyle, won three individual gold medals and three relay gold medals. The junior from Stanford went slightly faster in all three individual races. In the 50 freestyle, she improved to 25.60 from 25.65; in the 100 freestyle, she dropped from 55.34 to 55.25, and in the 100 butterfly, she posted a 59.33 after going 59.45 at nationals.
Davis, a Texas senior, won the 200 freestyle in 1:48.50, .84 faster than his second-place finish at nationals.
Bedford, who is also a senior at Texas, upset Stanford's Lea Loveless in winning the 200 backstroke in 2:10.97, 1.19 seconds faster than her runner-up finish at nationals.
Nall, the 200 breaststroke world record-holder from Towson, Md., did not improve her time by winning that race in 2:28.40, but her victory in the 100 breaststroke in 1:09.11, was .54 faster than her winning effort at nationals.
Like Larsen, Wagner, 16, of Gainesville, Fla., was competing in her first international meet. And as did Larsen, she showed a veteran's savvy, winning the 200 individual medley in 2:12.54, 1.8 seconds faster than the lifetime best she had posted at nationals. In the 400 individual medley, Wagner's 4:41.22 was 0.71 seconds faster than her lifetime best at nationals.
