SOCHI, Russia -- A Ukrainian cross-country skier has failed a doping test, her countrys Olympic committee said Saturday. Tajh Boyd Jersey . It is the third positive result of the Sochi Games. Marina Lisogor tested positive for trimetazidine, which is classified as a "specified stimulant" on the World Anti-Doping Agencys prohibited list. Specified substances are considered more susceptible to inadvertent use and can carry reduced penalties. The 30-year-old Lisogor competed in two cross-country events in Sochi, finishing far out of the medals. According to the Ukrainian Olympic Committee, Lisogor said she did not knowingly take a banned substance. Lisogors failed drug test follows those of German biathlete Evi Sachenbacher-Stehle and Italian bobsledder William Frullani. All three drug-test failures are tied to stimulants. The IOC is conducting 2,453 drug tests in Sochi, a record for the Winter Games. The Olympic body also stores Olympic doping samples for 10 years to allow for retesting when new methods become available. Sachenbacher-Stehle, a former two-time Olympic gold medallist , tested positive for methylhexanamine in both samples. The German Olympic Committee said she was being sent home. She blamed 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 Friday. Frullani was ejected from the games after testing positive for dimetylpentylamine. Frullani, who had not competed yet, asked for a backup test that confirmed the result. The Italian Olympic Committee told The Associated Press it believed Frullani, a former decathlete, bought the stimulant on the Internet from the United States since it is not available in Italy. Alex Green Jersey . While the spotlight has been on potential first overall draft pick Jadeveon Clowney and his 40-yard time, and top quarterback prospect Blake Bortles during the throwing drills, top prospects Greg Robinson and Sammy Watkins have impressed scouts enough to solidify or even boost their spots on draft boards. Antwan Barnes Jersey . Kawhi Leonard scored 20 points, Tony Parker had 16 points and 10 assists, and San Antonio rolled to a 114-97 victory over the Trail Blazers on Thursday night for a 2-0 lead in the Western Conference semifinals.DETROIT -- Will Power gave Roger Penske and Chevrolet what they desperately wanted by winning the first of two races at the Detroit Grand Prix. "On his home track and in Chevys backyard, its a perfect day," Power said Saturday. "If we can do it again tomorrow, itll be even better." Power finished 0.3308 seconds ahead of Graham Rahal on the bumpy, 13-turn, 2.36-mile street circuit on Belle Isle. He started a season-worst 16th and took the lead for good with just more than 10 laps to go when he passed Ryan Briscoe. "Theres no way we thought we would come from 16th to win," he said. "But this is IndyCar and anything can happen." The Australian held off Rahal to join Indianapolis 500 champion Ryan Hunter-Reay as the series drivers with two victories through six races. Power pulled within three points of Hunter-Reay, IndyCars points leader. James Hinchcliffe of Oakville, Ont., finished in sixth place. Power, who won IndyCars season-opening race, has 23 career victories to break a tie with Emerson Fittipaldi and Tony Bettenhausen and to match Tommy Milton for 18th on the all-time list. His latest victory was especially sweet for Penske and Chevy. Penske had not won an open-wheel race in the area he calls home since Helio Castroneves finished first in 2001. "Its sure a great piece of satisfaction for me to see this happen," Penske acknowledged. And for Chevy, which sponsors the race, it was a good day after being relegated to watching Honda dominate the previous three races over the last two years in the shadow of its world headquarters. "We swept the podium in 2012," Art St. Cyr, president of Honda Performance Development, said a few hours before Saturdays race. "We won both races last year, swept the podium in one race and had two of the three spots in the other race "There are a lot oof Chevy folks here, so you do walk around with your chest puffed out a little bit more. Tommy Bohanon Womens Jersey. " After the 70-lap race, Honda had to settle for Rahals second-place finish as its only driver on the podium. Rahal, whose only career victory was in 2008, had finished no better than 13th this year. "Its a great day for us with the year weve had and the luck weve had," Rahal said. Tony Kanaan was a season-best third followed by Justin Wilson and Castroneves, who was the pole-sitter and led a race-high 30 laps Saturday. "I wish I could relax," Kanaan said "My mind is already going on what I have to do tomorrow." Hunter-Reay, meanwhile, failed to follow up the biggest win of his career with a 16th-place finish. He was on the last lap, but did not make it to the finish line because he spun into a tire wall to end the race. He started 21st in the 22-car field because he brushed a wall on his second lap during Saturday mornings qualifying session. "We had a rough day overall," Hunter-Reay said. Simon Pagenaud and Mike Conway each won last year on Belle Isle and both lost their shot to win early Saturday. Pagenaud damaged his front left suspension when he ran into the back of Power, leading to a yellow. "I didnt even know where Pagenaud was," Power insisted. Conway did not have any one around him when he appeared to understeer into a wall on Lap 15, putting the race under caution. Both will get another shot to repeat at the Detroit Grand Prix on Sunday as part of IndyCars first of three doubleheaders this season. While Penske was thrilled with the victory after Castroneves was barely beaten by Hunter-Reays Honda-powered car last Sunday at the Indy 500, he knew there were fewer than 24 hours to celebrate before the next race on Sunday. "We all start from ground zero," he said. wholesale nfl jerseys ' ' '
