Kempe tied it 1-1 at 13:56 by scoring on a one-timer from the right circle set up by Kopitar. It was Kempe's 30th goal, becoming the first Los Angeles player to reach the mark since Kopitar (35) in 2017-18.
"His physicality, his pace, his shot have showed up night after night," McLellan said. "And we haven't had a 30-goal scorer here since I don't know when? And he's there now, so it's progress for our organization. It really is."
Gaudreau put Calgary ahead 1-0 10 seconds into the game, putting the puck on net from below the goal line and having it redirect in off Petersen. It was the second-fastest goal to start a game in the NHL this season; Anthony Beauvillier of the New York Islanders scored after nine seconds against the Detroit Red Wings on March 24.
"Just a lot of luck," Gaudreau said. "I just kind of fired it at the net, net front. I didn't even know it went in until I saw [Tkachuk] raise his hands up. … I mean, can't ask for a better start."
NOTES: Lindholm (35 goals, 35 assists) became the third Flames player with 70 points this season, joining Gaudreau (95 points; 34 goals, 61 assists) and Tkachuk (85 points; 32 goals, 53 assists). Only the Colorado Avalanche, with four players, have more. … Flames forward Ryan Carpenter had an assist for his first point in three games since being acquired in a trade from the Chicago Blackhawks on March 21. … Flames forward Calle Jarnkrok missed his second game because of a non-COVID-19 illness. … Kopitar (61 points; 18 goals, 43 assists) passed 60 points for the 13th time, passing Marcel Dionne (12) for most such seasons with the Kings.
