Senators 2, Penguins 1 (2OT): Colin Greening scored at 7:39 of the second overtime as host Ottawa got back into its Eastern Conference second-round series against top-seeded Pittsburgh.

After both teams failed to convert during a power-play opportunity in the second extra session, Senators defenseman Andre Benoit unleashed a shot from the right faceoff dot that Tomas Vokoun stopped. Greening grabbed the rebound and slid a backhand shot around the netminder from the doorstep for his third goal in as many games.

Captain Daniel Alfredsson scored to forge a 1-1 tie with 28.6 seconds left in the third period. Craig Anderson rebounded from a shaky performance in Game 2 to make 49 saves for seventh-seeded Ottawa, which looks to even the series when it hosts Game 4 on Wednesday.

Tyler Kennedy tallied and Vokoun turned aside 46 shots for the Penguins. Reigning Hart Trophy winner Evgeni Malkin was kept off the scoresheet, ending his eight-game point streak.

After a scoreless first period, Kennedy got Pittsburgh on the board with 1:07 remaining in the second as he received a pass from Matt Cooke following a turnover and rifled the puck into the top right corner of the net from the right hash marks. The goal stood to be the game-winner until Alfredsson redirected a perfect pass from high along the left-wing boards by Milan Michalek past Vokoun while his team was short-handed.
