Santo Domingo, Dominican Republic - Cuba dominated the Greco-Roman wrestling gold-medal finals of the Pan American Games on Sunday evening, winning top honors at all seven weight classes, including a victory by Mijian Lopez over 2000 Olympic gold medalist Rulon Gardner (Colorado Springs, Colo./Sunkist Kids) at 120 kg/264.5 lbs.    Lopez defeated Gardner, 5-0. It was the third time the 21 year-old has defeated Gardner this year, this time scoring on takedowns and his best move, the gut wrench.    But Gardner felt that Lopez was using his legs more than he should be allowed to in Greco-Roman wrestling, which requires the use of only the upper body on scoring attempts.    "He basically inside-tripped me twice during the match, but they weren't going to call that down here. That's fine. You have to expect those things when you travel overseas," Gardner said after his worst loss to Lopez in the three defeats.    "I'm right there. I've just got to get a little better footwork and get my core wrestling skills at 100 percent and then it will be there. I'm working to hard to try and out-pummel him and I just to not get so aggressive."    Lopez celebrated midway through the second period when he scored on a two-point gut wrench for his third and fourth points, giving him the necessary amount of points needed to win in international wrestling. He raised his arms and cheered loudly before realizing the match was still going.    Other U.S. wrestlers dropping gold-medal matches were Brandon Paulson (Anoka, Minn./Minnesota Storm) at 55 kg/121 lbs. and Brad Vering (Colorado Springs, Colo./New York AC) at 84 kg/185 lbs.    Paulson, a 1996 Olympic silver medalist and 2001 World silver medalist, lost to 2000 Olympic silver medalist Lazaro Rivas of Cuba 5-2. Rivas controlled the match the entire way, taking a quick lead on Paulson with a takedown and two gut wrenches.    It is the fifth loss in five attempts for Paulson against Rivas.    "He (Rivas) started off really fast. I don't know if I was ready for that. After the first minute when he scored three quick points, I thought I controlled the bout from that point on," Paulson said. "I think I'm ready (for the World Championships). I'm going to train my tail off and get ready to move Rivas' record to 5-1 against me."    Vering dropped a 6-0 decision to 1999 World Champion Luis Mendez of Cuba. Mendez also controlled the match throughout, scoring on three two-point gut wrenches in the win.    Capturing bronze medals for the U.S. squad were Jim Gruenwald (Colorado Springs, Colo./Sunkist Kids) at 60 kg/132 lbs. and T.C. Dantzler (Colorado Springs, Colo./New York AC) at 74 kg/163 lbs.    Gruenwald lost a semifinal match to Luis Liendo of Venezuela to send him into the bronze-medal match. Liendo defeated Gruenwald 3-2 in overtime. Gruenwald then came back to pin Arsenio Mitchell of the Dominican Republic to win the bronze medal.    Winning the gold medal at Gruenwald's weight was Roberto Monzon of Cuba, whom Gruenwald defeated in pool competition.    "I have no one to blame but myself. I've got to be the one to take control out there," Gruenwald said still speaking of his semifinal loss. "I let the bout get away from me early on, my heart was beating out of control.  I don't know what it was, pre-match adrenalin or what, but it was something I wasn't expecting."    Dantzler once again excited the crowd at the Pebellon de Combate. Trailing 3-2 late in the match against Sixto Barrera of Peru, Dantzler scored a takedown with 20 seconds remaining to tie the score at 3-3. As time was about to expire, Dantzler lifted Barrera and drove him to his back for three points and the win.    Justin Ruiz (Taylorsville, Utah/Dave Schultz WC) won a silver medal earlier in the day through round-robin competition in a pool of five wrestlers at 96 kg/211.5 lbs.    Kevin Bracken (Colorado Springs, Colo./New York AC) placed fourth at 66 kg/145.5 lbs., losing to Luis Fernando Izquierdo of Colombia in the bronze-medal match by a 4-3.    The U.S. Greco-Roman team placed second in the team race behind Cuba for the seventh consecutive Pan American Games competition.
