Ben Hutton's one-timer from the point went wide to Rinne's left but bounced back out to Baertschi, who fought off defenseman Shea Weber's check and backhanded the puck before Rinne could recover. It was Baertschi's 14th goal.
Dorsett scored 1:17 later after another tough bounce. Rinne stopped Burrows' shot from the right faceoff circle with his pad, but the rebound bounced hard off the back boards to Horvat on the other side of the net. Horvat's blind backhand pass went right to Dorsett at the top of the crease, and he one-timed it under Rinne for his fourth goal, ending a 29-game drought.
It was the second straight game the Predators fell behind 2-0; they came back to force overtime before losing 3-2 to the Calgary Flames on Wednesday.
Nashville coach Peter Laviolette said he isn't worried about the poor starts yet.
"Tonight, there's no question we didn't play very well in the first period and were slow to get off the mark," Laviolette said. "If something happens over and over and over again, you look at what are we doing wrong, but our team has been a really good starting team. I haven't seen a long-term problem, so hopefully there is not a long-term problem."
