PITTSBURGH — Three rookies led the NHL's last-place team to its second consecutive win.

Colby Armstrong had the first two-goal game of his career, Marc-Andre Fleury earned the second shutout of his career and Sidney Crosby posted two assists for the fifth time as the stripped-down Pittsburgh Penguins beat the Philadelphia Flyers 2-0 Sunday night.

Pittsburgh killed a 7-minute Flyers power play late in the game to preserve the shutout and prevent Philadelphia from moving into a tie atop the Atlantic Division.

"It was a great game by everyone and we played well together as a team," Armstrong said. "We did the right things, so it felt great to pull out a win like that."

The Penguins, whose 44 points are still five behind the next closest team, had six rookies in the lineup and only five with more than two seasons worth of NHL experience — the result of retirements, injuries and trades. But they have won two games in a row for only the fourth time this season.

Pittsburgh, which beat New Jersey 6-2 at home Saturday night, has yet to win three straight.

"We give a lot of chances to young players and that's the way we see things right now," Penguins coach Michel Therrien said. "But right now the work ethic is there, the conditioning is there, back-to-back games the way we played."

The Flyers, who are two points behind the Rangers, have not won a game in regulation since Feb. 10. They have two shootout wins and an overtime loss during that stretch. Philadelphia, which played for the fourth in seven days, lost 6-5 to Buffalo on Saturday.

"We just had an emotional week, and I think yesterday's loss took quite a bit out of us," Flyers coach Ken Hitchcock said. "We hit three goal posts, and we seemed to not have the energy, especially offensively, to do the things we needed to do."

Armstrong, who has goals in three consecutive games and points in eight straight, scored his first on a power play.
