Six past Junior National champions remained unbeaten after the first day of the ASICS/Vaughan Girls  Junior National Championship in Fargo, N.D., July 30.     The 2003 Junior National champions who advanced through the first day without a loss included Kelli Rasmussen of Minnesota at 110 pounds, Claire DuPont of Colorado at 110 pounds, Deanna Rix of Maine at 128 pounds and Ali Bernard of Minnesota at 150 pounds.    Rasmussen, who was the 101 pound champion a year ago, won four matches, three by pin and a 7-3 win over Emily Duckworth of Maryland.    DuPont is attempting to defend her 110-pound title from last year. She won three matches, all by technical fall, as well as receiving a bye.    Rix, the 119-pound champion last year, moved up in weight and is 5-0 after day one. She scored three technical falls, a pin, and a 6-0 decision over Tara-Patricia Williams of California.    Bernard is attempting to defend her 150-pound title. She has pinned all three of her opponents quickly, with fall times of 38 seconds, 35 seconds and 28 seconds. She won her pool, which places her in the championship finals on Saturday. Bernard was a 2004 U.S. Nationals champion on the Senior level, as well as a 2003 Junior World Champion.    A pair of 2002 Junior National champions were also unbeaten on Friday, Rachel Holthaus of Minnesota at 101 pounds and Amberle Montgomery of Washington at 128 pounds.    Holthaus was the 95-pound Junior National champion in 2002, and was runner-up at 101 pounds last year. She has three wins, two by pin and one by technical fall.    Montgomery was the Outstanding Wrestler of the 2002 Junior Nationals but did not compete last year. She won five matches on Friday, which guaranteed her a spot in the championship finals on Saturday. Included were two pins, two technical falls, and a 10-6 decision over Chelynne Pringle of Minnesota.    Along with Montgomery and Bernard, the other athlete who has clinched a position in the gold-medal finals was Melissa Simmons of Washington at 165 pounds. Simmons won all three of her bouts by pin.    In a highly-anticipated match between Senior-level stars, Na'Tasha Umemoto of Oregon defeated Stefanie Shaw of Connecticut 10-7 at 138 pounds. Umemoto was a 2004 U.S. Nationals champion on the Senior level at 130 pounds. Shaw placed fourth at the U.S. Olympic Team Trials in Indianapolis, Ind. in May. Both placed third at last year's Junior Nationals, Umemoto at 128 pounds and Shaw at 138 pounds.
