Jason Robertson completed his first career playoff hat trick midway through the third period as the Dallas Stars defeated the Edmonton Oilers 5-3 on Monday night to take a 2-1 lead in the NHL’s Western Conference finals.

Wyatt Johnston and Miro Heiskanen, into the empty net, had the other goals for Dallas. Jake Oettinger made 26 saves. Roope HintzTyler Seguin and Jamie Benn had two assists each.

“You want to help the team win, you want to score goals,” said Robertson, who hadn’t found the back of the net since Game 6 of the first round. “Scoring one gives you confidence … like a domino effect.”

Connor McDavid, with a goal and an assist to give him 100 career playoff points, Zach Hyman and Adam Henrique all scored for Edmonton, which got 17 stops from Stuart Skinner.

“A real good start,” McDavid said. “I’m not sure where those 10, 15 minutes come from, but it’s as bad as it’s been throughout the playoffs.”
