Backes broke a 1-1 tie 45 seconds into the final frame on a power-play goal, taking a cross-crease feed from T.J. Oshie and tipping it past Jimmy Howard. Berglund followed with the clincher less than 2 minutes later, unleashing a slap shot from the left circle on a 2-on-1 break.
Howard made 23 saves for Detroit, which lost a second straight contest following a season-high seven-game winning streak.
