David Backes gave the St. Louis Blues a big gift on his 32nd birthday, with another overtime goal to go home even.
Backes scored off a rebound during a power play 10:58 into overtime of Game 2 on Sunday for a 4-3 victory over the Dallas Stars.
After blowing a two-goal lead while getting outshot 13-2 in the third period, the Blues took advantage of their second power-play chance in overtime. Backes followed up Alexander Steen's shot 17 seconds after Antoine Roussel was called for interference, his third penalty in the game.
Blues goalie Brian Elliott had 31 saves, including big shots by Jason Spezza and Stars captain Jamie Benn about a minute apart in overtime.
St. Louis had a quick extra-man chance in overtime when John Klingberg was whistled for holding as Vladimir Tarasenko, who scored 40 goals in the regular season and four in the first-round series, was charging toward the net. But Niemi stopped three shots in that 2-minute span.
Spezza and Benn, who scored the OT-forcing goal with 2:36 left in regulation, then had their shots before the game-deciding penalty.
Troy Brouwer had a power-play goal and an assist in the first period to help the Blues take a 3-1 lead.
Benn knocked a loose puck past Elliott to tie the game at 3-all late in the third period, when Cody Eakin got his third assist of the game.
Stars rookie center Mattias Janmark had a breakaway goal 4 1/2 minutes into the third period, and Dallas was almost immediately on the power play after the ensuing faceoff. But the Stars were 0 for 4 with the extra man, and are now 1 for 20 on power plays at home this postseason.
Instead of a 0-2 hole, the Blues go home 1-1 in the best-of-seven series matching the Western Conference's top two teams. Game 3 is Tuesday night, with Game 4 also in St. Louis on Thursday before the series returns to Dallas for Game 5 on Saturday.
