In a matchup of teams riding four-game winning streaks something had to give. The Nashville Predators needed a little extra time to stretch their run to five. David Legwand scored the only shootout goal, Pekka Rinne finished with 39 saves and the Predators beat the St. Louis Blues 2-1 on Saturday night. Legwand drifted to his right before lifting a backhander over the outstretched glove of goalie Jaroslav Halak.
