Jake Guentzel scored twice, Zach Aston-Reese scored his first two NHL goals and the Pittsburgh Penguins beat the Ottawa Senators 6-3 on Tuesday night.
Evgeni Malkin scored his 31st and Kris Letang his fourth for the Penguins, who have won seven of nine and 12 of their last 16. Sidney Crosby, who scored his 400th career goal on Sunday, finished with three assists.
Pittsburgh is riding a nine-game home winning streak, the longest since a franchise-record 13-game run during the 2013-14 season. The Penguins haven't lost in Pittsburgh since a 4-0 defeat by Carolina on Jan. 4.
Matt Murray stopped 30 shots for Pittsburgh.
Derick Brassard, Colin White and Mike Hoffman all scored for the Senators, who lost for the third time in five games. The Senators dropped to 7-16-4 on the road. They were 22-17-2 away from home last season.
Guentzel scored his 17th on the power play and his 18th in the second period. Aston-Reese scored the first of his career in the second period and added an empty-net goal with 1:05 to play.
Mike Condon made five saves on nine shots before he was pulled after Aston-Reese's goal. Craig Anderson stopped 17 of 18 shots.
Guentzel, who set a Penguins rookie record with 13 goals in the playoffs, scored 12 goals in his first 27 games this season, but he had just four in his previous 30.
Aston-Reese, a finalist for the 2017 Hobey Baker Award, played in his first NHL game Feb. 3 at New Jersey and recorded his first point at Dallas six days later.
The Penguins opened the scoring with their first power-play goal in five games. Guentzel tipped a Justin Schultz point shot behind Condon for the early lead.
Brassard evened the score at 4:18 of the second period with a blocker-side slap shot from the left faceoff dot.
The Penguins reclaimed the lead for good 52 seconds later with Guentzel's second goal, a rebound from the top of the crease.
Murray made a sliding stop on Cody Ceci off the rush shortly after Guentzel's goal, allowing Malkin and Aston-Reese to break it open.
Carl Hagelin pulled Condon out of position when he circled the net. An unsuspecting Condon thought Hagelin still had the puck, but he blindly dished it to Malkin, who dumped a spinning bad-angle backhander into a partially open net.
Aston-Reese made it a 4-1 game 1:20 later. He took a pass from Crosby off the rush and flicked a wrist shot that hit Condon's glove and went across the line.
