PITTSBURGH -- Pittsburgh Penguins coach Dan Bylsma always preaches patience, especially on offense.
That did not change Sunday night when his team had its 11-game winning streak on the line.
"It was tough, hard-fought game and the Flyers did a good job of protecting around the net," Bylsma said. "We had some time in the offensive zone but it was tough getting inside and (goaltender Ilya) Bryzgalov was really good in the crease. We knew we wanted to keep getting pucks in there. We felt if we keep going, we would eventually get even."
That patience paid off for the Penguins again Sunday night as Tyler Kennedy's goal with 2:27 left in the overtime enabled them to keep their streak alive with a 2-1 victory over the Philadelphia Flyers at Consol Energy Center.
The Penguins have trailed in nine of the 12 wins during the streak. Five times, they have either been behind or tied after two periods, and Sunday night they were down 1-0 going into the third.
"We know to win a game we've got to play a full 60 (minutes) and we know we've got to stay on track," Kennedy said. "We always think we can win, regardless of the situation."
Sidney Crosby scored on a two-man advantage with 6:14 remaining in regulation to tie the score at 1-1. It was Crosby's 15th goal of the season and pushed his NHL-leading point total to 53.
The goal came 31 seconds after Kimmo Timonen was sent off for hooking. That came following a slashing penalty on Wayne Simmonds.
Crosby blasted a slap shot from the right circle past Bryzgalov, who was bidding for his 31st career shutout. Bryzgalov finished with 33 saves.
Kennedy took a pass from Matt Niskanen and beat Brzygalov high to the glove side with a slap shot from the left dot for his fifth goal as the Penguins pushed their Eastern Conference-best record to 25-8-0.
"I knew they were coming hard on Nisky and Nisky made an unbelievable pass," said Kennedy, who scored the third overtime goal of his six-year career. "I just shot it at the net."
Pittsburgh goalie Marc-Andre Fleury made 27 saves for his seventh win in a row.
"I thought our team played great, didn't give them many scoring chances," Fleury said. "Most of their shots came from the outside."
The Penguins are the first team in NHL history to have double-digit winning streaks in three consecutive seasons. The Flyers (13-16-2) have stopped the last two -- a 12-gamer on Dec. 14, 2010 and an 11-game on March 12, 2012 -- and seemed on the way to doing so again until Pittsburgh struck late.
"Our guys played hard," Flyers coach Peter Laviolette said. "I thought the third period was going the way we wanted to go until the penalty and that changed things."
After the teams combined to score 20 goals in their two previous meetings, the first goal on Sunday did not come not come until 14:09 of the second period when Philadelphia's Claude Giroux scored his 10th on a power play. On a length-of-the-ice rush, Giroux took a pass from Andrej Meszaros and found the back of the net with a wrist shot from the right circle.
Giroux played a big hand in the Flyers upsetting Pittsburgh in six games in the first round of last year's Stanley Cup playoffs as he scored six goals and had 13 assists.
Pittsburgh acquired Dallas Stars captain Brenden Morrow and a 2013 third-round draft pick during the game in a trade for defenseman Joe Morrow, the Penguins' first-round draft pick in 2011, who was playing at Wilkes-Barre/Scranton of the American Hockey League.
Brenden Morrow is expected to arrive in Pittsburgh on Monday and be in uniform for Tuesday night's game against the Montreal Canadiens. He waived a no-trade clause to come to Pittsburgh after also considering a deal that would have sent him to the Boston Bruins.
The 34-year-old left winger, who has spent his entire 14-year career with the Stars, has six goals and five assists in 29 games this season.
The Penguins plant to pair Morrow on the second line with center Evgeni Malkin and right wing James Neal.
"He's a guy that goes to those dirty areas and as you know when you get in the playoffs we know that's an important aspect of what we're trying to do," Pittsburgh general manager Ray Shero said.
