St. Louis made it 3-1 with a power-play goal at 14:38 of the second after David Backes picked up a loose puck and set sail the other way up the right wing before shifting to his backhand and sending a perfect pass to Oshie, who put it past Sanford from the slot.
Pietrangelo capped the scoring with a power-play tally at 7:11 of the final stanza after he let one rip from the left circle that hit off traffic in front, popped up in the air and fell in behind Sanford.
