The Senators went on to win the game 6-3 - extending their winning streak to five.
Ullmark earned his 17th win of the season in net for a Senators team looking to make a playoff push. They now hold a five-point lead in the Eastern Conference Wild Card with 75 points while the Blue Jackets are barely holding on to the second spot with 70.
The Swedish native who represented his team at the 4 Nations Face-Off has had a rough go at it recently, now allowing three goals in four of his past five starts.
But the former Vezina Trophy winner can ultimately be what the Senators need to get into the playoffs if he has more nights like he did recently against the Detroit Red Wings making 48 saves on 49 shots.
The Senators next game will be against the Toronto Maple Leafs on March 15th.
