NASHVILLE, Tenn. -- Given the recent history between the two teams, the winner and the scoring margin were pretty predictable.
Dating to last season, the Predators have beaten the Blues five consecutive times, with all five games decided by one goal. The Predators also ended the Blues' season-opening winning streak at two games.
"I was really concerned," Nashville coach Barry Trotz said. "I saw St. Louis on a lot of films and thought that they had a lot of detail in their game and they were really playing with a lot of pace. It was a great test for us and our guys responded really well."
Goc opened the scoring 56 seconds into the opening period with a wrist shot from the low slot, and Sullivan made it 2-0 on two-man advantage at 11:14 of the first.
With the Blues' Brad Boyes and Eric Brewer both in the penalty box, the Predators had their first five-on-three power play of the season. Nashville defenseman Ryan Suter faked a shot from the top of the right circle then passed to Sullivan all alone in the lower left circle where he buried a one-timer into an open net.
"It was just a great pass by Ryan Suter," Sullivan said. "He just kind of froze everybody with the fake shot."
After D'Agostini drew the Blues within one at 13:37 of the first, Sullivan answered 15 seconds later.
"I don't think we brought enough attention to the first period," Blues coach Davis Payne said. "We were slow to react, we were slow to move our feet and we took two penalties based on not moving our feet."
It was Sullivan's fourth goal on the season. He didn't score his fourth goal last season until Nov. 14.
Sullivan had an opportunity for his eighth career hat trick in the waning seconds of the first, but Halak stretched out his right leg pad to stop the breakaway attempt with two seconds remaining.
"I didn't score and they stayed in the hockey game for the most part," Sullivan said. "That's the most disappointing part. Hat tricks are great when they come, but the wins are more important."
Oshie scored an unassisted power-play goal at 8:15 of the second, but Hornqvist answered that with a power-play marker of his own at 16:21 to send the Predators into the second intermission up 4-2.
"My goal kind of sparked us a little bit and they got one right back," Oshie said. "One of our key things that we are working on this year is winning the battles every night, and I don't think we did that in the first."
Berglund's power-play goal at 5:13 of the third completed the scoring.
Playing in place of injured starter Pekka Rinne, Lindback has made the transition well to his first season in North America, stopping 62 of the 67 shots he has faced this season.
"Of course it is only just two games, but I am learning as I am doing it," the 6-foot-6 Swede said. "I'm having fun out there. I'm trying to get as much experience as I can."
