WATCH: [All Hurricanes vs. Penguins highlights]
"It's always great to get a shutout," Ward said. "I haven't gotten too many of those throughout my career, but it was a complete team effort. I thought our PK was really strong again. They have one of the top power plays in the League and I don't think I even faced a shot. So that's a kudos to the guys for stepping in and making some big blocks in big times of the game."
Pittsburgh did not register a shot on either of its two power plays.
Aho, who had one assist in addition to two third-period goals, has 10 points (six goals, four assists) during a six-game point streak. He said he was less interested in his individual achievements and more concerned with Carolina defeating a Metropolitan Division opponent.
"I think the most important points for our team are the two points," Aho said. "That's good for me. A good win for us."
The Hurricanes (19-13-8) have won eight of their past 11 games (8-2-1) despite losing their previous two (0-1-1).
Matt Murray made 29 saves for the Penguins (20-19-3), who have not won consecutive games since Dec. 1-2, when they defeated the Buffalo Sabres twice by a combined score of 9-1. They have been shut out in two of their past three home games, including 4-0 against the Anaheim Ducks on Dec. 23.
