Tyler Kennedy's marker with 2:27 remaining in overtime sent the Pittsburgh Penguins to their 12th straight win, courtesy of a 2-1 decision over Philadelphia at CONSOL Energy Center.
Kennedy cranked one home from the left circle, beating a screened Ilya Bryzgalov over his shoulder to the near post for the game winner, capping a rally from a late one-goal deficit.
Sidney Crosby also scored for the Penguins, who hung tough and did not let their in-state rivals play the role of streak buster for the second time in a little more than a year.
Pittsburgh had won 11 in a row until a Mar. 18, 2012 date in Philadelphia, but the Flyers' Scott Hartnell put an end to that run on his tally with less than a second remaining in OT to give the Flyers a 3-2 victory.
Marc-Andre Fleury made 27 saves for the Eastern Conference leaders, who announced prior to the game the acquisition of veteran forward Brenden Morrow from the Dallas Stars.
Claude Giroux tallied and Ilya Bryzgalov stopped 33 shots for the Flyers, who have lost six of their last eight outings but managed to pick up a point for the first time in those defeats.
The visitors began to flirt with disaster as Wayne Simmonds was called for slashing with 7:08 left in regulation. Chris Kunitz was stoned early in the advantage, as Bryzgalov turned away his backhander with 6:45 on the clock, but immediately thereafter, the hosts were given a two-man edge when Kimmo Timonen sat for hooking Kunitz on the chance.
Crosby evened the game 31 seconds later on a one-timer from the right circle off a dish from Paul Martin, but the visitors were able to prevent further damage during the following 5-on-4.
Fleury made a trio of saves -- one on Simmonds and two on Andrej Meszaros at the right post -- early in overtime to prolong the contest.
"We know to win a game you have to play a full 60 (minutes). We're a pretty confident team," Kennedy said. "We had to work hard and keep it going."
In a tight-checking first period, Fleury stopped six shots and Bryzgalov halted all nine he faced.
The Flyers finally snapped a scoreless tie in the late stages of a power play with 5:51 remaining in the second. Giroux carried into the Pittsburgh zone on the left wing, and though his initial shot was blocked by Tanner Glass, the rebound came back to the captain for a second successful chance.
Bryzgalov made a huge stop with 8:13 left in regulation. A failed Philly clearing attempt skipped back into the Penguins' attack zone, caromed off the stick of Flyers defenseman Luke Schenn and right to Kunitz, but his chop out of the air from atop the crease was trapped.
"I thought our guys did a real good job," Flyers coach Peter Laviolette said of his team's defense. "There weren't a lot of chances."
