Who will be competing at this division in Las Vegas? Who knows?    This is one of the three non-Olympic weight classes. There will be a U.S. Nationals competition at this weight class, even though it won't be contested in the Olympic Team Trials in Indianapolis, May 21-23. In fact, the top four placewinners in Las Vegas in the three non-Olympic division qualify for the Olympic Trials. Of course, they will have to pick one of the Olympic weights, up or down, for Indy.    The top athletes at this division from last year are expected to change weights, if not for the U.S. Nationals, certainly for the Olympic Trials.     2003 World bronze medalist Jenny Wong, ranked No. 1, is expected to move up in weight to 55 kg, where she has wrestled all year. U.S. Nationals champion Malinda Ripley could go down to 48 kg, although at the University Nationals she actually went up to 55 kg where she won the division.  No. 3 Danielle Hobeika is expected to move up to 55 kg, where she has competed some this year. Katie Kunimoto, who has been ranked in the top three here in the past, has already dropped to 48 kg for her last three tournaments.    Some of these athletes could choose to stay at 51 kg in order to take advantage of the qualifying spots in the top four. Although there are eight who qualify at the Olympic weights, those divisions will be jammed with many competitors. Since Ripley has yet to compete down at 48 kg, she is top ranked in TheMat.com rankings at 51 kg. The other top athletes have been placed in the rankings in their new weight division.    This could open the door to a new champion, perhaps a young athlete from the age-group levels. None of these young stars have really stepped forward and shown that they are favorites to win here. This could be the most wide open and unpredictable race in the entire tournament.    There have been three college wrestlers who have traded places in the women's college rankings all year, swapping wins and losses between them. They are Debbi Sakai of Missouri Valley, Kapua Torres of Pacific and Lauren Lindsay of Cumberland. At one point, each of these wrestlers have been No. 1 in the U.S. college rankings this year. Sakai had the best Senior level performance in the past, placing at the U.S. Nationals while in high school, but any of these three athletes could move ahead of each other during the tournament in Las Vegas.    Cheryl Wong has been competing on the national level for a few years, and may be the highest ranked athletes left if all the big names leave for other divisions. She wrestled at 55 kg at the University Nationals, so she may not be here, either.    Jillian Yost has been training this year some at the U.S. Olympic Training Center and entering some tournaments. She may have an edge against others who were not exposed to that kind of intense training situation. Jill Remiticado was a nationally ranked athlete at this division when she competed at Pacific Univ., but is now graduated. If she wrestles in Las Vegas, she has a chance to place high in the division.    Other collegians who have been active in this division this year include Tabithia Ramsey of UM-Morris, Maika Watanabe of Missouri Valley, Amy Borgnini of MacMurray and Sheila Lerit of Menlo. Ramsey won a gold medal at this division at the FILA Junior Nationals. Lerit has not wrestled nationally since January.    Melina Hutchison was second at the Dave Schultz Memorial at this division, her first major competition in a year. She has not wrestled since, but if she gets back down to this weight and has prepared well, she could place very high in the standings.    It would not be surprising to see a talented high school athlete sneak into the medal rounds if the division is thinned out from previous years. Exactly who that high school person might be is yet to be determined. Laine Orabona of North Carolina was third at the FILA Juniors at this division, the highest placing high schooler. Claire DuPont of Colorado won the Junior Nationals last summer at 110 pounds, but she has yet to enter a Senior-level event. If some of the competitors from the USGWA high school tournament give the U.S. Nationals a try, they might find some success.    Once the athletes get off the scales and we see who is left at 51 kg, then we have a better idea of the top prospects for winning the gold. Somebody will be left standing and qualify for the U.S. Nationals finals - who that will be is anybody's guess.    THEMAT.COM RANKINGS FOR APRIL 2004  51 kg (112 lbs.) in women's wrestling  1.
