DALLAS – Wyatt Johnston’s fourth career hat trick included two power-play goals, giving him an NHL-best 12, and Jason Robertson had the game-winning goal and two assists in his 400th career NHL game as the Dallas Stars beat the Ottawa Senators 6-1 on Sunday night.

Johnston also had an assist to match a season high with four points.

Mavrik Bourque and Jamie Benn also scored for the Stars, who have won four straight and are 10-1-1 in their last 12 games.

Dallas backup goaltender Casey DeSmith is 6-0-2 after making 15 saves. Dallas allowed a season-low 16 shots on goal.

Robertson’s goal came 44 seconds later after Jake Sanderson tied the score at 1-1. Dallas outshot Ottawa 3-1 in the second round, a scoreless first.

Johnston and Robertson led the team with 16 goals each, tied for fourth in the NHL. Robertson has points in 10 of his last 11 games (13 goals, 9 assists) and leads Dallas with 35 points (fifth).

Linus Almark stopped 20 shots for the Senators, who are 3-3-0 heading into the finale of a season-long seven-game road trip.

The Stars’ 38 points are second in the NHL but four behind league-leading Colorado in the Central Division.
