PITTSBURGH -- Bobby Ryan scored at 4:59 of overtime to give the Ottawa Senators a 2-1 win over the Pittsburgh Penguins in Game 1 of the Eastern Conference final on Saturday night at PPG Paints Arena.
Ryan came out of a tangle along the right-wing boards for a short breakaway and roofed a shot past goaltender Marc-Andre Fleury.
Craig Anderson finished with 27 saves for the Senators, who improved to 6-1 in overtime in the playoffs. The Penguins are 1-1 in overtime.
Game 2 is Monday night in Pittsburgh.
This is the fifth playoff series between the clubs; Pittsburgh has won three of four and three straight.
The Penguins started the night leading the playoffs with 41 goals, an average of 3.4 per game. They also have the leading scorer in the playoffs in Evgeni Malkin, who began the night with 18 points, and four of the top seven.
But Ottawa stood firm through more than two periods and killed off all five Pittsburgh power plays during regulation.
Pittsburgh had 5:50 of power-play time in the first period, including 45 seconds of five-on-three play, but it was Ottawa that scored first.
From behind the Penguins' net after a turnover by Pittsburgh defenseman Brian Dumoulin, Ryan sent a soft backhander out front to Jean-Gabriel Pageau, who one-timed the puck past the glove of Fleury at 14:32.
It was Pageau's eighth goal, one behind playoff leader Jake Guentzel of Pittsburgh. Pageau had 12 goals during the regular season.
The assist was Ryan's seventh of the playoffs after he had 12 during the regular season.
The Senators nearly claimed a 2-0 lead at 12:48 of the second on a wraparound play by Alexandre Burrows. The puck snuck its way past Fleury at the right post, but officials ruled the whistle blew first.
Malkin tied it 1-1 at 14:25 of the third on a tip-in from Chris Kunitz for his 19th point. It also lifted Malkin past Jaromir Jagr into third place on Pittsburgh's all-time playoff points list with 148.
That ruined Anderson's shot at his second shutout of the playoffs.
