MOSCOW, Russia – Nobody could fault the effort of American wrestler Justin Ruiz Ruiz fought gamely, but fell just short of winning a medal as the World Championships kicked off on Monday at the Olympiysky Sports Complex. Ruiz battled back to win two repechage matches before falling to Sweden’s Jimmy Lidberg 1-0, 1-0 in the bronze-medal match at 96 kg/211.5 lbs. Ruiz won a World bronze medal in 2005. He was making his fifth appearance at the Worlds, but first since 2007. "It's been a while since I've been at this level," Ruiz said. "I was excited about every match. I wasn't thinking about end results, places and medals. I wanted to wrestle, to do my best and win." Lidberg successfully defended Ruiz in the first period and was then able to turn him late in the second period to prevail. Lidberg was a 2009 World silver medalist. "I felt good going into the match," Ruiz said. "In the first period, I got a lock but couldn't get a turn. In the second period, he had a couple good attempts I fought off. My mistake was I was preparing for another attempt and he caught me going the other way. It cost me the match." The 31-year-old Ruiz opened with a 1-0, 1-0 win over Richard Karelson of Estonia before falling to Timofej Dzeinichenka of Belarus 0-1, 2-0, 4-0 in the second round. Ruiz charged at the Belarus wrestler in the third period, but was caught with a three-point move when his attack was countered with a throw. U.S. coaches protested the scoring, but it was upheld. Ruiz came back in the repechage to earn wins over Sabhui Humbatov of Azerbaijan and Yunior Estrada Cuba before battling Lidberg for the bronze medal. Americans Faruk Sahin and Spenser Mango fell short of medals on Monday. Sahin opened with three-period wins over Tomasz Swierk of Poland and Tero Valimaki of Finland before falling to Ukraine’s Arman Vardanyan 2-0, 1-0 in the quarterfinals at 66 kg/145.5 lbs. Vardanyan is a two-time World silver medalist and Olympic bronze medalist. Sahin was then eliminated in the repechage when he lost 3-0, 3-0 to Olympic gold medalist Steve Guenot of France. Guenot had lost to Vardanyan earlier in the tournament. Sahin was wrestling in his second World Championships. “I understand this is my second World Championships,†Sahin said. “I have seen a lot. I haven’t wrestled the guy who I lost to. He is very experienced, and has medaled a few times. He lifted me with two seconds left. My preparation, I felt was great. Sometimes, you have to have luck. The last two seconds, he got the lift. I guess things happen. I need to focus on winning. These are good experiences. I am learning a lot. It is not easy winning the Worlds.†Mango dropped his first match to 2008 Olympic champion Nazyr Mankiev of Russia at 55 kg/121 lbs. Mango was eliminated when Mankiev fell one match short of reaching the finals. Mango dropped a 1-1, 1-0 decision to Mankiev. Mango scored on a pushout with 20 seconds left in the first period before Mankiev countered with a takedown with 12 seconds left. Mankiev then turned Mango with 13 seconds left in the second period to clinch the win. Mango, a 2008 Olympian, was wrestling in his second straight World Championships. "I feel like I am right there,†Mango said. “It's little things, nothing major. I have to work on fixing those mistakes. I was expecting him to bring me back through and I would get some repechage matches. It didn't happen this time. I have to work on my mistakes and come back next year."
