SWIMMING : Thompson Overcomes to Win 100

Jenny Thompson, the bionic woman of American swimming with a plate and seven screws holding her left arm together, scored her second victory Wednesday in the National Swimming Championships.

Thompson won the 100-meter butterfly in 1 minute 0.34 seconds, catching runner-up Amy Van Dyken just before the finish with a final split of 32.04 seconds. Van Dyken was second in 1:00.57.

“I was really nervous coming into this meet. I didn’t know what to expect,” said Thompson, who had surgery June 3 to repair the arm she broke while riding a waterslide on the Stanford campus.

In men’s competition, Chad Carvin and Seth van Neerden recorded their second victories in the competition, used this year to select the U.S. team that will participate in next month’s World Championships at Rome.

Kelli King-Bednar won the other event, completing the 100 backstroke in 1:10.46.

Carvin, who set American records while winning the 500- and 1,650-yard freestyle events for Arizona in this year’s NCAA meet, had a personal best of 3:49.83 in winning the 400 freestyle. He also won the 200 freestyle.

Van Neerden, the 26-year-old from Wilmington, Del., who swims for the Ft. Lauderdale Swim Team, added the 200 breaststroke title to his 100 breaststroke victory earlier this week.

Van Neerden won in 2:13.27, the fastest time in the world this year.
