Tierney set up a pair of power-play goals -- albeit one into an empty net -- Thursday in a 2-0 win over the Predators. A sparking outing for Tierney, who skated a season-high 16:04. That's a promising sign for the 20-year-old rookie, who's provided four points over the last four games. However, he hasn't put a single shot on goal in six of his last seven contests.
