Bryan Rust scored a tiebreaking goal midway through the second period and the Penguins avoided the embarrassment of being swept by the lowly Devils with a 4-3 victory on Tuesday night.

Penguins coach Steve Sullivan said his team was really good in the second period when it scored twice to take a 4-2 lead.
"I think at this time of the year guys are playing so hard that the games are so tight," he said. "We need everybody to have the juice. We need to play the game the way we want to play it. so I thought our second period was really strong, but thought the guys played hard all night."
Matt Murray made 33 saves, including 15 in the third period, to help the Penguins salvage the final game in the four-game season series.
