PRETORIA, South Africa - Oscar Pistorius is a "paradox" whose past triumphs as a sprinter crossing the finish line with raised arms contrasted sharply with the daily, severe limitations that he endured because of his disability, a physician testified Thursday at the runners murder trial. Wayne Derman, a professor of sport and exercise medicine at the University of Cape Town, said in court that the contrast likely contributed to stress and anxiety for Pistorius, who fatally shot girlfriend Reeva Steenkamp through a closed toilet door in his home. He testified for the defence, which wants to show that the athlete had a deep sense of vulnerability and it was a factor in what he has described as a mistaken shooting. "Youve got a paradox of an individual who is supremely able, and youve got an individual who is significantly disabled," said Derman, who has worked with South African Olympic and Paralympic teams and has treated Pistorius over half a dozen years. He noted that Pistorius anxieties included concern about flying. "He has a specific fear of being trapped somewhere without being able to move very rapidly," Derman said. Referring to Pistorius decision to confront a perceived threat on the night he killed Steenkamp, Derman said "fleeing was not an option" because the runner has no lower legs. Pistorius, 27, says he killed Steenkamp on Feb. 14, 2013 by mistake, thinking there was a dangerous intruder in his home. He shot her while on his stumps. The prosecution says he intentionally killed the 29-year-old model after the couple had a Valentines Day argument. Pistorius, who is free on bail, faces 25 years to life in prison if found guilty of premeditated murder, but he could also be sentenced to a shorter prison term if convicted of murder without premeditation or negligent killing. Additionally, he faces separate gun-related charges. During cross-examination, prosecutor Gerrie Nel said Derman, the physician, was giving "character evidence" rather than "expert evidence" and questioned whether the witness was capable of giving testimony that would work against Pistorius defence. "The truth would come before my patient," Derman said. Nel countered: "You cannot give evidence against your patient, sir." Blue Cowboys Jerseys .

Ryan Callahan scored a power-play goal midway through the third to give Tampa Bay its fifth straight win, 5-4 over Ottawa, and hand the Senators their fifth loss in a row. Tampa, who sits second in the Atlantic Division with 83 points and 11 games remaining, is peaking at the right time. "We just seem to be scoring tons of goals," said Lightning goaltender Ben Bishop, who stopped 27 shots for his 34th win of the season. "Were rolling right now and we have a big game against Pittsburgh so hopefully we can keep it going." The Senators have talked about the need to play better and play smarter, but head coach Paul MacLean says its the same mistakes that keep coming back to plague his team time and time again. "Groundhog day," MacLean said. "Thirteen giveaways, six minor penalties, we played too much in our zone and ends up in the same thing." Teddy Purcell scored twice for the Lightning (39-24-7). Valterri Filpulla and Eric Brewer also scored. Clarke MacArthur, Erik Karlsson, Ales Hemsky and Milan Michalek scored for the Senators (28-28-13). Robin Lehner faced 28 shots as he lost his sixth straight game. Trailing 5-4, Ottawa had a great opportunity to tie the game as Callahan took a penalty with 55 seconds remaining in regulation. With Lehner on the bench, the Senators had a two-man advantage, but were unable to beat Bishop. "We competed to the end, but once again we didnt find a way to win," said Senators captain Jason Spezza. "We fought right to the end, but once again we found a way to lose." Callahans power-play goal midway through the third had given the Lightning a 5-3 lead, but the Senators made it a one-goal game as Michalek deflected a Karlsson shot from inside the blue-line at 17:07. Brewer scored his first goal in 95 games to give the Lightning a 4-3 lead at 3:48 of the third with a great shot off his backhand to sneak the puck in under the crossbar. "Ive seen him do that a few times," said Bishop. "Hes good for a couple of those a year." Hemsky made it 3-3 after displaying some great puck handling before beating Biishop late in the second.ddddddddddddThe goal earned him a standing ovation from the 17,136 on hand. "Its a nice goal, but in the end it really doesnt matter if you lose," said Hemsky. "The people reacted great." Asked if he minded being the goalie on the end of Hemskys highlight-reel goal, Bishop could only laugh. "It doesnt really matter when you win," he said. "It doesnt matter how many highlight goals they score if we win the game." The Lightning had taken a 3-2 lead at the five-minute mark of the second period on a power-play goal by Filpulla, who knocked home a rebound just out of Lehners reach. Lehner was at a loss for words after the game. "What is there to say now, I dont know, its pretty empty," he said. "Its tough to be in there right now. I can say again, yeah I sucked a Im trying to be there and trying to step up to make saves, but the players are so good in this league and they get too much time. Its tough. "I dont think the effort has been the biggest issue this year. I think were cheating some times. We go really offensively and then its pretty empty back home." The Senators ended the first period tied 2-2 after getting off to a horrible start. Purcell, who hadnt scored in his last 19 games, opened the scoring just 23 seconds into the game. Ottawa managed to tie the game on MacArthurs short-handed goal midway through the period. It was MacArthurs 21st of the season, tying a career high. The Lightning regained the lead on Purcells second of the night as he managed to dig the puck out through traffic in the crease and then shoot it in off the post. Karlsson rounded out the scoring with a power-play goal, beating Bishop with a shot from just inside the blue-line. Notes: G Craig Anderson (upper body injury) and G Nathan Lawson (lower body injury) missed the game. D Patrick Wiercioch and LW Matt Kassian were a healthy scratch for the Senators a The Lightning signed free agent forward Cody Kunyk to a one year, two-way NHL contract. Kunyk, 23, skated in 37 games for the University of Alaska-Fairbanks Nanooks this season, posting 22 goals and 43 points.
