Jarry is 9-0-1 in his past 10 starts, allowing fewer than three goals six times.
"I just think he's competing," Penguins coach Mike Sullivan said of Jarry. "When he's at his best, it's economy of motion with his movement in the blue paint. He's got a calm demeanor to his game. I think that rubs off on our team. That's why I preface it with saying he's competing hard.
"There's always that fine line between composure or poise and nonchalance. We want to be on the right side of that line. I think he's on the right side."
Sidney Crosby nearly gave the Penguins a lead at 11:14 of the third, but shot wide after getting behind Stars defenseman Esa Lindell and taking a pass from Guentzel to go in alone. Crosby went without a point for the fourth time in 18 games since Nov. 5.
