The surging Bruins gave themselves a nice early Christmas present last night in the Music City, a 6-2 victory against the Predators. “It’s always more fun when you’re winning,” said B’s goalie Tuukka Rask, who stopped 32 shots. “I was pretty happy with how we finished off these last four games. We played some good hockey and got a good road win here to finish it off. It’s a good break for us now.” It was a productive night for several Bruins, led by Carl Soderberg (fifth goal, plus two assists), Jarome Iginla (ninth and 10th goals), Ryan Spooner (three assists) and Reilly Smith (12th goal, two assists). Matt Fraser netted his first goal as a member of the Bruins, and Brad Marchand notched his eighth of the season. The B’s scored six goals for the first time in 2013-14. The Bruins scored on their three power plays, each time getting just one shot during the advantage. Even more promising, they scored on each of their three power plays, all three times finding the back of the net with the first shot of the man-advantage. It was the first game with three power-play goals this season for the Atlantic Division-leading B’s, who scored three times in the third period, snapped a two-game road losing streak, and are 13-4-1 overall in their past 18. “I thought we played a pretty solid game,” said coach Claude Julien, who earned his 400th NHL win. “They had some chances, but Tuukka came up big for us. They still played a pretty tough game. We stood in, held our ground and made the most of our chances.” The game wasn’t as easy as the score suggests. The hard-working Predators cut the lead to 3-2 with Craig Smith’s second goal of the night 3:25 into the third period. But they took back-to-back minors shortly after, setting the B’s up with a 5-on-3 for 1:37. The visitors didn’t need it all. They got goals from Iginla (a midair tap-in of a David Krejci pass) and Soderberg (set up nicely in front by Spooner) that made it 5-2 at 5:51. “They make it 3-2 and our power play did a great job getting a couple of goals and putting a seal on that win,” Julien said. “It was a big night for our power play.”
