SOCHI, Russia -- A top German biathlete and an Italian bobsledder were kicked out of the Sochi Olympics on Friday in the first doping cases of the Winter Games. Acheter Air Max 95 Pas Cher . Former two-time Olympic gold medallist Evi Sachenbacher-Stehle tested positive for the stimulant methylhexanamine in both her "A" and "B" samples, the German Olympic Committee said. The committee said she has been removed from the team and was being sent home. Sachenbacher-Stehle -- winner of two golds and three silvers in cross-country skiing at previous games -- blamed the positive test on a nutritional supplement and said she had never knowingly taken performance-enhancing drugs. "I am going through the worst nightmare that you can imagine, because I am unable to explain at all how there could be a positive test," she said in a statement. The Italian Olympic Committee, meanwhile, announced that bobsledder William Frullani was ejected from the games after testing positive for the banned stimulant dimetylpentylamine in the athletes village on Tuesday. Frullani, who had not competed yet, asked for a backup test that "confirmed the positive result, resulting in his exclusion from the Italian delegation," CONI said. The IOC declined to comment, citing confidentiality of ongoing anti-doping procedures. Sachenbacher-Stehle, who switched from cross-country to biathlon two years ago, competed in five events in Sochi but did not win any medals. Her best results were two fourth-place finishes, in the 12.5K mass start and the mixed relay. The 33-year-old German was tested after Mondays mass start race. Her backup sample was tested on Friday and confirmed the original finding. Her expulsion from the games was announced after she appeared before an IOC disciplinary commission on Friday afternoon. Sachenbacher-Stehle had been left off Germanys top-ranked womens relay team before Friday nights 4x6-kilometre relay. The team finished 11th. Franziska Hildebrand, who skied the third leg for Germany, said the team was told about the doping case earlier in the day. "We are totally shocked," Hildebrand said. Methylhexanamine is classified on the World Anti-Agencys prohibited list as a "specified stimulant," a group of substances that are more susceptible to inadvertent use and can carry reduced penalties. Sachenbacher-Stehle said she had her nutritional supplements checked in a lab or cleared by the manufacturer before the games. "At the moment I can only assure all involved that I never knowingly took banned substances," she said. Any further sanctions outside of the Olympics are up to the International Biathlon Union. The German could face a ban from the sport for a year or more. Michael Vesper, chief of German Olympic body DOSB, said athletes have been repeatedly warned about supplements that contain methylhexanamine. "The DOSB strives for a doping-free sport and a zero tolerance policy," he said in a statement. "We strive only for cleanly achieved performances. Every doping case is first of all a big disappointment. But it is also proof that that control system works." Stefan Schwarzbach, spokesman for the German biathlon and cross-country teams, said a contaminated supplement is a possible explanation for Sachenbacher-Stehles positive test. "We are not sure if its really from an unproven, or dirty, supplement," he said. " We really dont know." "It really seems that it is a mistake," Schwarzbach added. "And she has to handle the consequences." As a cross-country skier, Sachenbacher-Stehle won gold medals in the team sprint at the 2010 Vancouver Olympics and 4x5K relay at the 2002 Salt Lake City Games. She won silver medals in Salt Lake, Vancouver and at the 2006 Turin Games. The only previous German athlete sanctioned for doping at a Winter Olympics was hockey player Alois Schloder, who was disqualified from the 1972 Sapporo Games after a positive test for ephedrine. German-born cross-country skier Johan Muehlegg was competing for Spain in 2002 when he was caught doping and stripped of one of his three gold medals at the Salt Lake City Olympics. In the Italian case, CONI told The Associated Press that it believed Frullani, a former decathlete, purchased the stimulant on the Internet from the United States, since it is not available in Italy. Dimethylamphetamine is also classified as a "specified stimulant" on the WADA list. Samuele Romanini will replace Frullani as the brakeman for the four-man bobsled race, which begins Saturday. The IOC is conducting 2,453 drug tests in Sochi, a record for the Winter Games. The IOC also stores Olympic doping samples for 10 years to allow for retesting when new methods become available.

Sixteen teams have moved on. Sixteen teams have gone home. CHICAGO -- Theo Epstein was the first person to take a chance on Felix Doubront. Now he is going to give the struggling left-hander another opportunity. The Chicago Cubs acquired Doubront from the Boston Red Sox on Wednesday in exchange for a player to be named. Epstein, the president of baseball operations for the Cubs, was Bostons general manager when Doubront signed with the Red Sox as an undrafted free agent in 2005. Cubs manager Rick Renteria said he didnt know very much about Doubront, and the team said it would announce in the next couple days where he would begin with the organization. Doubront pitched against the Cubs on July 2, allowing three runs and four hits in 1 1-3 innings of relief. "I reserve my right to come to my own judgment on what hes about," Renteria said. The 26-year-old Doubront had grown unhappy with his role in Boston. He was shuttled to the bullpen during the playoffs last year, when the Red Sox won the World Series for the third time in 10 seasons. He made four appearances in the post-season, allowing one run in seven innings. He was again bumped from the rotation this season -- and again expressed his displeasure. But Doubront did little to pitch himself back into a starting role. He recorded just two outs in his final appearance with Boston on Monday, allowing six runs in mop-up duty in a 14-1 loss to Toronto. As the defending World Series champions fell further into last place in the AL East, it became obvious they had little use for a disgruntled and ineffective reliever. Doubront won 11 games in eaach of the previous two seasons. Vapormax Pas Cher Chine. He struck out 167 in 161 innings in 2012. But he was 2-4 with a 6.07 ERA in 17 games, 10 starts, with the Red Sox this year. The trade is Epsteins fourth deal with his former team since he took over the Cubs in October 2011. It could be the start of a busy week for the plummeting Red Sox, who have conceded their title defence after losing eight of their last nine games. Starters Jon Lester and John Lackey are also on the trading block. The Cubs also could be active ahead of Thursdays non-waiver trade deadline. Utilityman Emilio Bonifacio did not play in Wednesday nights 10-inning loss to Colorado, with Renteria acknowledging the trade talk surrounding the speedy switch hitter. "Im just waiting for whatever is going to happen," said Bonifacio, who is batting.400 (14 for 35) in his last eight games. Also Wednesday, Chicago completed this weeks trade with Los Angeles when it received minor league pitcher Jonathan Martinez from the Dodgers. The Cubs sent second baseman Darwin Barney to the NL West leaders on Monday. Martinez, a 20-year-old right-hander, was 7-5 with a 3.47 ERA in 19 starts for Class A Great Lakes this season. He was signed by the Dodgers as a non-drafted free agent in May 2011 out of Venezuela. The Cubs also recalled left-hander Chris Rusin from Triple-A Iowa and sent right-hander Blake Parker to their top farm club. Parker pitched two innings as the Cubs used eight relievers in Tuesday nights 4-3 victory over Colorado in 16 innings. ' ' '
