The 2002 United States National Wrestling Championships was an outstanding showcase of the best that wrestling has to offer, in all three styles of international wrestling. Those who attended the gold-medal finals of the competition will have many memories to enjoy.    It was a tournament that featured a number of established stars continuing to move forward with successful international careers. However, in many weight divisions, new stars have emerged with first-time victories and are setting the stage for a run at the a spot in the 2004 Olympic Games in Athens, Ga.    Let's take a look at each style, beginning with men's Greco-Roman...    Established stars ruled the day in Greco-Roman, as you might expect in a style that is currently ranked No. 3 in the world. Of the seven champions, six have won previous national titles.    Leading the pack was 1996 Olympic silver medalist Brandon Paulson of the Minnesota Storm, who claimed his second national title with a 6-1 win over Lindsay Durlacher of the Wildcat WC at 121 pounds. Paulson was a 2001 World silver medalist, and broke the match open with a three-point throw in the second period.    Other past Olympians to win gold medals this year in Greco-Roman were 2000 Olympic bronze medalist Garrett Lowney of the Minnesota Storm at 211.75 pounds and 2000 Olympian Kevin Bracken of the New York AC at 145.5 pounds. For Lowney, it was a second national title, while Bracken has now claimed the title four times, including three in a row.    Lowney stopped Justin Ruiz of the Dave Schultz WC in the finals, 5-0. Ruiz had beaten Lowney on the age-group level back in 1999, but Lowney's Greco-Roman career has blossomed since. In a battle of 2001 World Team members, Bracken beat Marcel Cooper of the Marines, 4-1 in the finals. It was Bracken's third straight U.S. Nationals title    Past World Team members who captured golds were U.S. Army stars Keith Sieracki at 163 pounds and Dremiel Byers at 264.5 pounds. Another Army champion was Glenn Nieradka at 132 pounds, who was selected as the Outstanding Greco-Roman wrestler.     Sieracki defeated his top rival in recent years,  T.C. Dantzler of the New York AC, 4-1 in the finals. Byers used a powerful bodylock throw from the clinch position to break a 0-0 tie and pin Billy Pierce of the Minnesota Storm in 3:14. It was Sieracki's third career U.S. Nationals title, while Byers won his second career gold.    Nieradka won the Outstanding Wrestler after beating two of the nation's best athletes in a row. In the semifinals, he beat Dennis Hall of the Sunkist Kids, a 10-time national champion, Olympic silver medalist and World Champion in overtime. In the finals, he beat Olympian Jim Gruenwald of the Sunkist Kids by a 4-2 margin, again in overtime. It was Nieradka's second career title.    By capturing three of the seven individual titles the Army won the Div. I team race, with 45 pts. with the U.S. Marines in second with 40 pts.    The only new Greco-Roman champion was Ethan Bosch of the New York AC, who scored a 6-2 win over Brad Vering of the Sunkist Kids in the finals. Bosch, who has been close many times, has been competing in this event for 10 years before getting his title.    The freestyle field for men also featured a mix of new talent and veteran stars. Two wrestlers won their third career National crowns: Joe Williams of the Sunkist Kids at 163 pounds and Kerry McCoy of the New York AC at 264.5 pounds.    Williams captured his gold medal with a 9-1 decision over Casey Cunningham of the Sunkist Kids and was named the Most Outstanding Wrestler. McCoy, who has won his three titles in a row, needed overtime (and three winning clinches) to stop Tolly Thompson of the Sunkist Kids, 3-0. McCoy was the only past Olympian to win a freestyle national title.    Taking their second U.S. National titles were Eric Guerrero of the Gator WC at 132 pounds, Bill Zadick of the Hawkeye WC at 145.5 pounds and Cael Sanderson of the Sunkist Kids at 185 pounds. All three beat their opponents in the finals by 4-0 scores.    Guerrero defeated Eric Akin of the Dave Schultz WC in the finals in regulation. Zadick went into overtime before beating Jamill Kelly of the Gator WC. Sanderson scored four one-pointers on his way to a win in regulation over Lee Fullhart of the Hawkeye WC.    The two new freestyle champions were Teague Moore of the Gator WC at 121 pounds and Tim Hartung of the Minnesota Storm at 211.25 pounds. Moore was in control for a 7-2 win over Jody Stittmatter. Hartung, trailing 2-1, locked up a cradle late in the match and did not let go, scoring a 4-2 win over Chad Lamer of the Hawkeye WC.    The Div. I champions in freestyle was the Sunkist Kids, followed by the Dave Schultz WC. In Div. II, the New York AC took the prize, followed by the Gator WC.    In women's freestyle, two of the sport's veteran stars won titles again, as Stephanie Murata of the Sunkist Kids captured the 121 pound title and Lauren Lamb of the Michigan WC grabbed the 130-pound title.    Murata won her seventh National tournament with a 6-2 win over rugged Malissa Sherwood of Stars and Stripes. Lamb, who won her first National event as a teenager in 1991, scored in overtime to top Erin Tomeo of the Sunkist Kids, 6-5.    Two wrestlers claimed their third straight titles, Sara McMann of the Sunkist Kids at 138.75 pounds and Iris Smith of the U.S. Army at 158.25 pounds.    McMann defeated five-time World medalist Kristie Stenglein-Marano 7-1 in the finals match. Smith, the first woman champion for the U.S. Army, stopped Kaci Lyle of Pacific, 6-0 in the championship.    Winning her second straight gold, as well as her second straight Outstanding Wrestler award was Toccara Montgomery of the Sunkist Kids, who put away Katie Downing of Minnesota-Morris in a 12-1 technical fall. Included was a double leg takedown to a five-point throw that excited the crowd.    The two lightest weight classes featured new champions, Patricia Miranda of the Dave Schultz WC at 105.5 pounds and Jenny Wong of the Sunkist Kids at 112 pounds. Miranda won a 10-0 technical fall over Julie Gonzales of the Schultz club, while Wong stopped another Dave Schultz Club athlete Danielle Hobeika by a 9-4 margin.    The Sunkist Kids edged Missouri Valley College for the team title by one point, 41 to 40 points.
