Kings defenseman Matt Greene whipped the puck deep into the Blackhawks’ end of the ice early in overtime of Game 7 of the Western Conference finals on Sunday. Teammate Justin Williams hustled after it a nanosecond later and gained control behind the net.

Williams then slipped a pass to defenseman Alec Martinez, who closed quickly from the left point. Martinez snapped a shot toward the net. The puck skimmed past the outstretched stick of teammate Tyler Toffoli, struck Chicago’s Nick Leddy and settled into the net.

Suddenly, silence.

Well, almost. The only sounds in the mammoth United Center just then were the screams and shouts of the victorious Kings, who celebrated Martinez’s goal and a clinching 5-4 win over the Blackhawks that sent them to their second Stanley Cup Final appearance in three seasons.

“I didn’t know it was in until I saw (Kings teammate Jarret Stoll) going bananas,” Martinez said.

The Kings advance to play the New York Rangers, the Eastern Conference champions. Game 1 is Wednesday at Staples Center.

“The journey’s not done yet,” Kings goaltender Jonathan Quick said.

Williams, Toffoli, Jeff Carter and Marian Gaborik also scored for the Kings, who won their third consecutive Game 7 on the road. They rallied from deficits of 2-0 and 4-3 and never led until Martinez scored at 5 minutes, 47 seconds of sudden-death OT.

Brandon Saad, Jonathan Toews and Patrick Sharp, who scored twice, had the goals for the Blackhawks. Chicago ended the Kings’ reign as champions by defeating them in the conference final last season en route to its second title in four seasons.

“It’s kind of hard to put everything into words right now,” said Kings center Anze Kopitar, who assisted on Gaborik’s tying goal at 12:43 of the third period. “Deep down, we felt we could do this. Coming from behind the whole game, being in a loud rink (and) Chicago’s playing good.

“To get it done really shows the character we have in this room, and that really is priceless. I don’t know what to say anymore. We kept battling. It was not easy out there. We had to kill a 5-on-3, a bunch of 5-on-4s. Kudos to everybody in here.”
