Jake Muzzin skated into open ice and snapped a shot through traffic and past Corey Crawford only nine minutes into Game 4 of the Western Conference finals Monday. Marian Gaborik then redirected a centering pass into the net a little while later and Dustin Brown scored a little bit later still.

Suddenly, remarkably, the Kings were headed to a 5-2 victory over the Chicago Blackhawks and were one win away from their second trip to the Stanley Cup Final in three seasons. And to think, they did it with offense again at Staples Center.

Where’s it coming from?

“I don’t know,” Muzzin said, laughing.

After a regular season in which they went through scoring droughts that were measured in weeks and months rather than games, it seems the Kings can score almost at will during the playoffs. They have outscored the Blackhawks 15-7 in the last three games.

Game 5 is Wednesday in Chicago and the Kings can advance to play either the New York Rangers or Montreal Canadiens for the Stanley Cup. The Rangers lead the Eastern Conference final by three games to one going into Game 5 tonight in Montreal.

“We need four to win the series and we’re going there to win one more,” Muzzin said.

Chicago is where the Kings’ hopes of a repeat of their 2012 Stanley Cup championship died last spring, with a double-overtime loss to the Blackhawks in the decisive Game 5. Now they have a chance to end the Blackhawks’ chances to win a second consecutive title.

“It stings a little bit,” Muzzin said of thinking back to last June 8 and Patrick Kane’s three-goal game in a the Kings’ 4-3 loss at the United Center in the clinching fifth game of the series. “You obviously want to win. You learn from it, move on, get better and here we are.”

Muzzin, Gaborik and Brown gave the Kings a 3-0 lead by the end of the first period, easing goaltender Jonathan Quick’s burden with an electric opening 20 minutes. Muzzin and Brown scored on the power play, which improved to 16 for 56 (28.6 percent) over the last 16 playoff games.

The Kings’ power play clicked at 15.1 percent during the regular season, 27th in the NHL.

Gaborik’s goal was at full strength, but showed the Kings’ superiority in the subtler aspects of the game. Anze Kopitar made the play happen by pressuring Blackhawks defenseman Duncan Keith along the boards and then swiping the puck from the Norris Trophy finalist.
