If there is an athlete on the U.S. Greco-Roman scene who has established himself as the dominant force in his division, that person could be Brad Vering of the New York AC at 84 kg. Vering has represented the U.S. at the last three World-level events, placing fifth at the 2002 and 2003 World Championships and competing at the 2004 Olympic Games. Vering still has dreams of winning the World Championships and Olympic Games, and is making a commitment to another four-year Olympic cycle.    Vering has competed very well this season, with some strong international performances under the new rules. He kept his edge over the rest of the domestic field by winning the gold medal at the U.S. Nationals this year.     Keith Sieracki of the U.S. Army placed second at the U.S. Nationals, losing in the finals to Vering by a close 1-0, 1-0 margin. Sieracki was the No. 1 athlete at 74 kg last year, and has moved up in weight for this season. His brother Aaron has competed up at this weight class in the past, but Aarong has not competed this season. Keith Sieracki has always competed well at 84 kg, and has moved up to test this field a number of times. If he remains at this division, his experience and talent makes him the biggest threat to Vering for the U.S. World Team spot.    The other athlete who has given Vering a strong test in the past is Jake Clark who was second behind Vering at the 2003 World Team Trials and the 2004 Olympic Team Trials. Clark did not compete in Las Vegas at the U.S. Nationals this year, but if he does enter the World Team Trials, he is expected to be a strong challenger for the title. Clark has been assigned overseas with the U.S. Marines but can return to compete in the United States, and remains one of the best Greco-Roman wrestlers in the nation.    Ther rest of this field is a bit inexperienced, meaning that the veteran stars could have a strong edge over them in the Challenge Tournament portion of the World Team Trials. Placing third at the U.S. Nationals with his best performance ever was Jake Plamann, who lost to nVering in the quarterfinals, then wrestled back with four straight wins to claim the bronze medal. Plamann proved he could win close matches, and will enter the event in Ames with renewed confidence.    Placing fourth at the U.S. Nationals was young Chas Betts, who has developed into a national contender as part of the USOEC resident program at Northern Michigan Univ. Betts was seeded seventh in Las Vegas, and won three straight matches in the consolation rounds for his best performance on the Senior level.     Among the other athletes who are making a move in Greco-Roman wrestling is John Wechter of the Michigan WC, who placed fifth at the U.S. Nationals this year after paying his dues in recent seasons. Wechter won bronze medals at the Sunkist Kids International Open and New York AC Christmas International, and has seemed to do well under the new wrestling rules.    Brad Ahearn of the U.S. Army captured sixth at the U.S. Nationals, qualifying for the semifinals where he won the first period but lost a very tight match to Vering. Ahearn's wrestleback losses came to Betts and Wechter, both three period battles.     Justin Millard of the U.S. Air Force was the final qualifier for the U.S. Nationals, by placing seventh in Las Vegas. Millard has been a Greco-Roman specialist in recent seasons, and won the University Nationals title earlier this year, then followed it up by capturing a spot on the University World Team with a victory in the Trials event in Colorado Springs.    Two athletes have been added to the field by winning Regional titles this spring, Michael Mathers of the U.S. Army and Zac Dominguez of the Sunkist Kids. Both  have been active on the Greco circuit in recent seasons, and will be looking to move up in the standings at the World Team Trials.    Veteran wrestlers like Aaron Sieracki of the U.S. Air Force and 2000 Olympian Quincey Clark of the Minnesota Strom are eligible to enter.    2005 U.S. NATIONALS RESULTS AT 84 KG/185 LBS.  1st - Brad Vering, Colorado Springs, Colo.
