SOCHI, Russia -- A Ukrainian cross-country skier has failed a doping test, her countrys Olympic committee said Saturday. Air Vapormax Rebajas . 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.

They started shooting the puck. Joe Pavelski had a hat trick to move into a tie for second in the NHL in goals and the Sharks beat Philadelphia 7-3 Thursday night in the first game for both teams following the Olympic break. Raffi Torres and Logan Couture each scored twice in their return to San Joses lineup following injuries. The Sharks trailed 2-1 after getting outshot 10-4 in the first period. San Jose made a pointed effort to shoot the puck in the second period and it paid off in a big way, resulting in five second-period goals on 16 shots. "We started to finally shoot the puck," Couture said. "The first period we werent shooting. We were playing in their end, but we werent shooting. Thats more the way we play, the way we need to play. A lot of our goals were off rebounds, and thats the way you score in this league." Pavelski, one of the Sharks four Olympians, scored all three of his goals in the dominating second period. Torres, who was making his 2013-14 debut after injuring his knee in the preseason, capped the second-period spree with his second goal of the game with 2.2 seconds left. Couture, who missed the previous 16 games due to hand surgery, netted his 15th goal of the season in the period. "We didnt have a lot of purpose in our game in the first period, especially in their zone," Sharks coach Todd McLellan said. "Kind of skating around waiting for something to happen. We got our forecheck going in the second (and) a lot more pucks to the goaltender, which created second and third chances. We had to start thinking about throwing the puck from bad angles and creating second (chances) that way." Andrej Meszaros had a highlight-reel tally and Matt Read and Brayden Schenn also scored for the Flyers, who had won four straight before the Olympic break. Flyers coach Craig Berube wasnt pleased with his teams effort, particularly the play in front of their own goal. "Not competing around our net, thats basically what it boils down to," Berube said. "Not getting sticks, not boxing people out, not being hard on people. We didnt compete hard enough to win the hockey game. Nobody. "Were all embarrassed tonight." The Flyers netted a pair of goals within a 22-second span midway through the first period to take a 2-1 lead. Meszaros, one of five Flyers who participated in the Olympics, opened the Philadelphia scoring with 9:24 remaining in the opening period. Alex Stalock, San Joses backup goalie who started in place of Olympian Antti Niemi, saved Meszaros initial shot from the point, but Steve Downie pushed the rebound to Meszaros, who shot the puck between his own legs and past Stalock from close range. Schenn put Philadelphia ahead 2-1 when he backhanded the puck from behind the net off the skate of Jason Demers and past Stalock with 9:02 remaining in the first period. Nike Air Max Tn Rebajas. But it was all San Jose in the second period. Pavelski scored from close range on the power play 4:23 into the period and then gave San Jose the lead for good with 9:48 remaining in the period when he deflected Marc-Edouard Vlasics shot from the point past Steve Mason that made it 3-2. Mason was lifted 35 seconds later when Couture tallied on a rebound after the Flyers goalie dropped a shot that he initially gloved. Mason gave up four goals on his first 13 shots. His replacement, Ray Emery, didnt fare much better, as Pavelski scored on a turnaround from in front of the crease with 5:50 left in the period for his 32nd goal of the season, tying him with Torontos Phil Kessel for second-most in the league. Torres finished the second-period scoring by just beating the intermission buzzer with a close-range goal. "We had some good luck throughout the team," Pavelski said. "They were just going in tonight. Life is good. Hopefully they keep coming." The sellout crowd loudly booed the Flyers as they exited the ice following the period. "We lost a lot of battles the last two-thirds of the game," Philadelphias Scott Hartnell said. "Simple penalties, turnovers that led to odd-man rushes and we were soft in front of our net. Thats what you get when you dont play tough, you dont play strong and you dont play good defence. It couldve been 10-3." It didnt get any better in the third period for Philadelphia as Couture netted a short-handed goal 4:50 in on a backhander in front of Emery. In a rare move, Emery was lifted and Mason was re-inserted into the game with 9:11 left in the third period. Emery requested to be removed from the game due to an undisclosed injury that neither he nor Berube would identify. Besides Meszaros, Flyers Michael Raffi, Jakub Voracek, Kimmo Timonen and Mark Streit also participated in the Olympics. Timonen, who helped Finland to the bronze medal, was a healthy scratch to allow him to rest. In addition to Niemi and Pavelski, San Joses Patrick Marleau and Vlasic competed in Sochi. Niemi, who entered second in the NHL in wins (29), didnt see any action Thursday. Demers, Andrew Desjardins and Marleau each had a pair of assists for the Sharks. NOTES: Before the Olympics, Niemi was 7-3 with a 2.12 GAA in his previous 10 starts.
