At a glance, spectators watching Mat 1 in the first session of the U.S. Olympic Team Trials at the RCA Dome in Indianapolis, Ind., might not have noticed anything different about Stefanie Shaw's 6-0 victory over Molly Keith.    Spectators also might not have paid too much attention to the age of Vanessa Oswalt as she stepped to the mat immediately after Shaw's win, and beat Iris Mucha 4-3.    Shaw and Oswalt are two of six high school students wrestling this weekend for a chance to make the inaugural U.S. Olympic women's freestyle team.     For Caitlyn Chase, a sophomore at Illinois wrestling powerhouse Glenbard North, the hardest part is simply telling people where she's going.    "My friends at school really don't understand the training that goes into something like this. They say, 'Oh, you'll win it,' but I have to explain to them just because I win at high school nationals that doesn't mean I'm going to win here."    The high schoolers went 5-1 in the first round, but the road got tougher … a lot tougher.     Only Shaw remains in the championship bracket and the could be the trend-setter for future women's Olympic hopeful, should she knock off world bronze medallist Sally Roberts, win the finals of the challenge tournament and then beat Sara McMann twice.     It's a long shot.    Jimmy Carr made the men's freestyle Olympic team in the 1972 Munich Games while in high school and Mark Fuller made the team in Greco-Roman in the 1984 Los Angeles Games.     Chase fell to top-seed Clarissa Chun 12-2 at 48kg in the second round. Vermont's Courtney Martell fell in the first round to Lauren Lamb. The only fall recorded was by Minnesota's Ali Bernard at 72kg, as she bested Kelly Branhan of Missouri Valley.    Malinda Ripley, a resident athlete at the Olympic Training Center and former women's high school wrestling standout, isn't wrestling this weekend. She's recovering from elbow surgery. But Ripley, two years removed from high school, remembers the 2000 U.S. Open in Las Vegas she entered as a junior in high school. She was the proverbial "deer in the headlights."    "My first year in opens was the same way. I went out there in shock and lost to two girls I shouldn't have. I was like 'Oh my gosh!'" Ripley said.   For Chase and Bernard, the second round, they were the deer and two challenge tournament top-seeds were the trucks barreling down at them. Bernard fell to Stephany Lee 9-5.     Shaw and Oswalt met in Friday night's quarterfinals with Shaw winning by pin at 5:23 with a 5-3 lead and the right to meet Roberts in Saturday's semifinals.  "I'm so overwhelmed right now," Shaw said.    "I can always count on her (Oswalt) to give me a good match."  A junior at Westport (Conn.) High School, Shaw is wrestling in only her second senior-level event.  Her first was the regional qualifier in Brockport, N.Y. … last month.    Should a loss come and the Cinderella run ends for the six pre-collegians, 2008 is already in sight, but in wrestling for the 2004 team, a loss is still a loss.     "(My advice) is not to get discouraged when you move up to something new. It's supposed to be difficult, but it will come," Ripley said.  "Going from high school and winning all the time, I had to learn how to lose; then you learn how to win again."    Chase sees not her age being a factor, but the fact she lacks the senior level experience needed to have a chance to be successful.    "These women have the experience and they're used to their bodies. They've all wrestled each other, and I haven't wrestled them before because they were at the senior level," Chase said.    Mary Kelly, a sophomore at McMurray College in Illinois, routinely competed in Fargo at the Cadet and Junior Nationals against the boys and has been wrestling (and winning) in senior level events since she met the required age of 17.    "(Wrestling on the senior level) makes you feel like you have more of an edge when competing on your own level," Kelly said.    Shaw and the rest of the high schoolers in Indianapolis this weekend are building for the future.    "It shows me, if nothing else, I can say 'I made it this far.' I've always wanted to try for the Olympics," Shaw said.
