NASHVILLE, Tenn. (AP) — Ryan Hartman got a bit nervous with the puck so close to the empty net after a shot by P.K. Subban.The Nashville forward wound up with not only the first playoff goal of his career but the winner with 1:09 left as the Predators held off the Colorado Avalanche 5-4 Saturday for a 2-0 lead in their first-round Western Conference series. Hartman's goal gave the Predators a 5-3 lead until Alexander Kerfoot pulled Colorado to 5-4 with 35.8 seconds left. But the Avalanche couldn't get another puck past goalie Pekka Rinne.
