OTTAWA, Ontario (AP) — Mark Stone and Matt Duchene each scored twice and the Ottawa Senators beat the Pittsburgh Penguins 6-4 on Saturday night.

Duchene also had an assist for a three-point night, Brady Tkachuk and Cody Ceci added goals, and Craig Anderson made 31 saves. The Senators have won two straight to improve to 9-8-3.

Pittsburgh captain Sidney Crosby missed his second straight game because of an upper-body injury. The Penguins are 1-7-1 in their last nine and 7-8-3 overall.

Kris Letang, Zach Aston-Reese, Matt Cullen and Patric Hornqvist scored for Pittsburgh. Matt Murray allowed three goals on 10 shots in the first period, and Casey DeSmith gave up three goals on 15 shots in relief.

After struggling through the first two periods and finding themselves down four goals, the Penguins rallied early in the third when Aston-Reese put in his first of the season and Cullen followed to make it 5-3.

But Drake Batherson fed Duchene for a breakaway to make it 6-3. With just under four minutes remaining, the Penguins pulled DeSmith and were able to take advantage when Hornqvist tipped a shot past Anderson.

NOTES: Ottawa’s Max McCormick and Christian Jaros were healthy scratches. … Derick Brassard returned to the Penguins’ lineup after missing nine games with a lower-body injury. Brassard returned to Ottawa for the first time since being acquired by Pittsburgh on Feb. 23.
