Jason Robertson had a goal and two assists, Mikko Rantanen had three assists, and Roope Hintz had two assists for Dallas (17-5-4), which has won four in a row and is 5-0-1 in its past six games. Casey DeSmith made 15 saves.
“Probably our most complete game for me of the year,” Stars coach Glen Gulutzan said. “The big four: goaltending was great, [power play] was great, the [penalty kill] was real solid, and I thought our 5-on-5 play was probably the best of the year defensively. When you get all four of those things working, it’s hard to beat.”
Jake Sanderson scored for Ottawa (12-9-4), which has lost three of its past four games (1-3-0). Linus Ullmark made 20 saves.
“It wasn’t pretty. This is one of those games you’ve got to turn the page and get ready for the next one,” Ottawa forward Ridly Greig said. “It’s the end of a (seven-game) road trip here, (we) got to find some legs for the next one (at the Montreal Canadiens on Tuesday).”
Mavrik Bourque gave Dallas a 1-0 lead at 1:58 of the second period when Ilya Lyubushkin’s shot from the right point deflected in off him at the left post.
Sanderson tied the game 1-1 at 8:36, scoring five-hole from the left circle after Shane Pinto forced a turnover by Jamie Benn along the right boards.
“I thought after two periods we were down and we had some plays that we didn’t like, but we were still in the game at that point. We had another period to play and they came out and kind of just took over the game,” Sanderson said. “They won the special teams battle tonight. I thought our power play honestly kind of drained some of our game. Not sharp, not crispy. You never know, if we get one on the power play and get some momentum, the game changes.”
Robertson put Dallas back in front 2-1 at 9:20. After Tim Stutzle lost control of the puck along the right boards, no Senators player went to pick up Robertson, who skated slowly into the slot before beating Ullmark glove side.
Robertson has scored a goal in nine of his past 10 games (13 goals during span).
