Nashville's Mike Fisher redirected Roman Josi's shot late in the second period for the go-ahead power-play goal, and the Nashville Predators hung on to beat Chicago Blackhawks 3-2 Friday. Fisher's goal was Nashville's third with the man advantage. P.K. Subban, Nashville's big offseason addition, scored the first goal of the season and Josi had a power-play goal. Marcus Kruger and Niklas Hjalmarsson scored for Chicago, which has lost its first two games this season playing with six rookies in the lineup. The Blackhawks have allowed six power-play goals in their first two games. Edmonton's Connor McDavid had a goal and two assists for his second straight three-point game to lead the Oilers over Calgary 5-3. Leon Draisaitl had two goals and Jordan Eberle and Mark Letestu also scored to help the Oilers complete a sweep of the teams' season-opening home-and-home series. Sean Monahan and Michael Frolik scored for the Flames, who have not won any of their past six home openers. Philadelphia's Boyd Gordon and Sean Couturier scored 48 seconds apart to kick off a four-goal second period that lifted the Flames to a 4-2 win against Los Angeles. Couturier got two goals and Mark Streit also scored for the Flyers, who won their season opener for the first time since 2011. Drew Doughty and Brayden McNabb scored in the home opener for the Kings, whose 50th anniversary season is off to an 0-2 start. Ducks re-sign Rakell Swedish forward Rickard Rakell agreed to a six-year, $22.8 million deal Friday to stay with the Anaheim Ducks. Rakell has 29 goals and 49 assists in 165 games for the Ducks, who drafted him in the first round in 2011. He scored 20 goals for Anaheim last season while ranking fourth on the team with 43 points, emerging as one of the Ducks' top young offensive threats. The restricted free agent didn't participate in training camp while technically holding out for a new deal, although he would have been unable to play anyway after surgery last month related to his appendectomy last spring. The surgery kept Rakell out of the World Cup of hockey, but the 23-year-old is working out again in Sweden with hopes of returning to hockey before the end of October. He will return to Anaheim when his visa is acquired, and he is expected to play on one of the Ducks' top two lines. "It's something we both agreed was common ground for the two of us," Ducks general manager Bob Murray said. "The injury held us up a little bit. We wanted to be totally comfortable Ricky was going to be OK going forward. He's over 200 pounds right now and he's skating."
