Wyatt Johnston posted the fourth hat trick of his career and added an assist to lead the Dallas Stars to their fourth straight victory with a 6-1 thrashing of the visiting Ottawa Senators on Sunday.

Johnston's three goals give him 16 on the season, including an NHL-best 12 on the power play after two on Sunday. The 16 overall goals ties him for the team lead with Jason Robertson, who had a goal and two assists in the win. Mavrik Bourque and Jamie Benn also scored. Mikko Rantanen added three assists, and Roope Hintz helped on two for Dallas, which is 10-1-1 in its last 12 games.
