Lehtonen was sharp in the first period, stopping all nine shots he faced as the Stars and Predators played a scoreless first 20 minutes. Lehtonen had big stops on Ryan Johansen breaking in on net and then on a Craig Smith blast from the slot with Nashville on the power play.
There was no scoring in the second as 12 of the 20 minutes of the period were played with players in the penalty box. The Predators had three power plays, the Stars had two power plays, and the two teams played two minutes of four-on-four hockey. Nashville had a 14-7 shots advantage in the second, but Lehtonen continued to be sharp in goal for Dallas, making seven saves on the Predators' three power plays in the period.
Nashville broke the scoreless tie when the Stars turned over the puck in their own end and Colton Sissons set up Hartman, who roofed a backhand shot at the 5:33 mark.
The Stars killed off a fifth Nashville power play, and Lehtonen made a great save on Filip Forsberg with the two teams playing five-on-five to keep it a one-goal game, but the Stars couldn't get much pressure on Rinne. Nick Bonino sealed the win with an empty-net goal with 14 seconds remaining to make it a 2-0 final.
