Matthew Tkachuk was a monster for the Flames, scoring two goals - including the tying tally - and adding an assist, having a part in all three Calgary markers.
He was physical. He showed his skill. He did it all and was named the game's first star.
The homeside trailed 2-0 after 20 minutes and were outshot 20-3, two of those Flames shots coming in the final minute of play.
Tyler Toffoli got the first tally for the visitors. Kings defenceman Drew Doughty - booed every time he touched the puck due to his ongoing feud with Tkachuk - got two shots on net, the rebound from the second one coming out to Ilya Kovalchuk, who won a battle with three Flames to chip the puck out of the scrum right onto the stick of a swooping Toffoli, who snapped it past Rittich.
Bookending the period, Sean Walker got the second Kings marker with 2:34 left to play, firing a puck from a sharp angle out by the boards - parallel to the net - that somehow squeaked shortside between Rittich and the pipe.
Inbetween, there weren't a lot of highlights for the homeside.
Tkachuk did throw two big hits on Doughty - the second one leading his D partner Kurtis MacDermid to grab Tkachuk and subsequently get sent off for roughing.
On the ensuing Calgary man-advantage, a tic-tac-toe play between Johnny Gaudreau, Tkachuk, and Sean Monahan led to the centre's shot ringing off the post for their best scoring chance of the frame.
Rittich's best stops of the first came on a pair of shots by Alex Iafallo, who took a behind-the-net feed from Anze Kopitar and got two whacks at the puck in tight in the blue paint but was denied.
Tkachuk had a golden chance just 30 seconds into the second, but lost the handle on the puck as he went airborne near the crease.
Kovalchuk then made it made it 3-0 at the 3:46 mark. Rittich made a stop on a point shot off his blocker, but the puck went straight up in the air and the Russian sniper was able to smack it out of the air and under the pipe.
The officials reviewed the play to see if it was a high stick but the call stood.
Later as Lucic skated the puck up the ice, MacDermid threw a hit on him, the two big men colliding solidly at centre ice. As they skated towards the corner, they both threw the mitts for a quick fight with a handful of punches thrown.
Just past the midway point of the period, Tkachuk grabbed the puck off a Kings turnover and snapped a wicked wrist-shot low, far-side past Jack Campbell from the high slot.
