Pittsburgh won all eight games against an once-dominating opponent that has won an average of nearly two of every three games played in the last 40 years between the Pennsylvania rivals. The Penguins went unbeaten against Philadelphia once previously, going 5-0-2 in 1992-93, but had never previously swept every game in a season.
They nearly didn't this time, falling behind 2-0 in a sloppily played first period in which Mike York and Braydon Coburn scored. But Gary Roberts scored once and set up the Penguins' other two goals in regulation as Pittsburgh won for only the second time in five games after getting points in 16 consecutive games (14-0-2).
Crosby decided a shootout for the second time in four days, following up Christensen's successful shot against goalie Martin Biron by stickhandling the puck down the slot before going to his backhand to end it.
Both Flyers shooters, Martin Ruzicka and Scottie Upshall, failed against goalie Marc-Andre Fleury after Christensen beat Biron by going to his forehand after faking a backhander. The Penguins are 7-5 in shootouts and the Flyers are 1-6, last winning on Oct. 26.
Crosby is only 3-of-11 on shootout attempts this season, but also decided the Penguins' 4-3 victory against the Rangers on Thursday by scoring the only goal of the shootout.
