AUSTIN, TEX., AUG. 2 -- Mike Barrowman said today the length of his fingernail, about half an inch, kept him from additional swimming immortality.

Barrowman missed breaking his own world record in the 200-meter breaststroke by two hundredths of a second Wednesday night at the long-course national championships. His time was 2 minutes 11.55 seconds, just short of his effort 13 days ago, when he broke his own record by swimming 2:11.53 to win the Goodwill Games gold medal.

"Half an inch over 200 meters kind of gets you a little upset," said Barrowman, of Potomac, Md. "If I had just touched a little bit faster . . . but don't get me wrong. I'm as pleased as can be with the win."

Defending champion and American record-holder Tracey McFarlane was unable to compete in the women's 200 breaststroke because she was hospitalized with severe flu. In her absence, Tori DeSilvia, 16, won her first national title.

Although DeSilvia won the race, McFarlane earned a place on the U.S. team for the world championships based on her time at the Goodwill Games.

Chrissy Ahmann-Leighton, a junior at the University of Arizona, earned her first national title in winning the 100 butterfly. She upset top-seeded Summer Sanders, fresh off a triple gold-medal-winning performance at the Goodwill Games.

Dan Jorgensen successfully defended his 400 freestyle championship.
