Rust pushed it to 3-0 at 9:03, tapping in a loose puck in the crease off a backhand pass from Jake Guentzel. Sidney Crosby had the secondary assist to extend his point streak to eight games (five goals, five assists).
The Penguins have altered their power play, splitting Crosby and Evgeni Malkin between the two units. Letang elevated to the point on the first unit, moving fellow defenseman Erik Karlsson to the same spot on the second.
“Sometimes you just need change,” said Guentzel, who played his 500th NHL game. “And when it's not going well, change is inevitable. ... It's a little bit of a wakeup call for us to move the puck a little quicker and just get shots on net."
Mark Scheifele, returning after missing six games with a lower-body injury, seemed to cut the deficit to two goals with a one-timer at 6:44 of the third period, but the goal was waved off when the play was ruled offside following a Penguins coach’s challenge.
"We had a ton of good looks. [Jarry] made some big saves,” Scheifele said. “They blocked a lot of shots, had some good sticks. I don't think it's anything to get frustrated about. We made a lot of good plays. We had a lot of good entries. Nothing to be frustrated about there."
