BRISBANE, AUSTRALIA, AUG. 15 -- David Wharton tonight completed a rousing double over world-record holder Alex Baumann in the Pan Pacific championships by winning the 200-meter individual medley by a hundredth of a second.

Dan Veatch of Rockville, Md., also was a winner over a Canadian, powering home over the final 50 meters to take the 200-meter backstroke in 2:01.38, an .18-second margin over Mark Tewksbury, as the dominant United States team took seven of the eight gold medals at stake tonight. That ran its meet total to 19 golds in 24 races.

Janet Evans, 15, of Placentia, Calif., and Australia's Nicole Livingstone, 16, each collected a second individual gold medal in the four-day meet. Evans added the 400-meter freestyle (4:09.32) to her 400 IM title. Livingstone took the 200 backstroke to go with her 100 backstroke gold and did it in 2:11.84, fastest time in the world this year.

Matt Cetlinski of Lake Worth, Fla., took the men's 400-meter freestyle in 3:49.51, second-fastest time in the world this year. Angel Myers of Americus, Ga., won the women's 200 individual medley in 2:17.52. The Americans won both 400-meter relays, with Matt Biondi earning his third gold medal of the meet and Dara Torres her second.

Wharton, 18, of Warminster, Pa., upset the veteran Baumann in 2:02.49 in the 200 IM. He swam a world-record 4:16.17 in beating Baumann in the 400 IM Friday night.

In the 200, Baumann led by more than a body length at the final turn. But Wharton picked up the pace. In the backstroke, Veatch rallied past Tewksbury in the final strokes.
