LAS VEGAS — A four-goal lead in what has been a wacky, compelling and highly entertaining Stanley Cup Final nearly wasn’t enough for the Golden Knights on Saturday night.

A four-goal, third-period rally by the Hurricanes nearly made NHL history and in process sent shockwaves through T-Mobile Arena.

And this game ended in a way perhaps befitting all the craziness, a shot from Vegas defenseman Shea Theodore off the skate of Brandon Bussi — the backup goalie put in the game in the third period after not playing for two months — that went into the net at 5:38 of double overtime to give the Golden Knights a 5-4 victory over Carolina.

“I have experienced a lot of games in playoffs,” Golden Knights coach John Tortorella said. “I haven’t experienced one like this.”

Almost overlooked was the four-point night by Vegas’ Mitch Marner, who also produced the fastest hat trick in Cup Final history.

The Golden Knights took a 2-1 series lead. The teams take two days off before meeting in Game 4 on Tuesday night in Las Vegas. Teams with a 2-1 series lead have gone on to win the Cup 46 of 57 times, or 80.7%.

Carolina had been 6-0 in overtime this postseason. The Hurricanes were trying to become the first team to win after trailing by at least four goals in the third period, but now clubs in that situation are 0-109.

The Golden Knights seemed to have it in hand after scoring four times in the second, including a natural hat trick by Marner.

But Jordan Martinook, Taylor Hall and Jordan Staal scored goals for the Hurricanes. Their goals, occurring 39 seconds apart, are the fastest three in a Cup Final game.

Andrei Svechnikov jammed in a puck on a 6-on-4 power play with 1:42 left to force overtime.

“I love that we feel like we can come back from anything, but you can’t put yourself in a hole like we did,” Martinook said. “The second period, for them to come out like that and take total control of the game, it’s something that can’t happen, especially this time.”

Marner’s scoring outburst came over a 6:10 stretch of the second period, and he had four points in the period. He had the secondary assist on Tomas Hertl’s goal midway through the period.

The last time a player had four points in a period of the Cup final was in 1919 when Frank Foyston of the Seattle Metropolitans pulled off that feat.

Marner nearly added to the total in the third period, but failed to capitalize on a breakaway and a penalty shot. Those missed chances came back to bite the Golden Knights.

The Hurricanes made the comeback after changing goalies to open the third, going with Bussi, who made 18 saves. Frederik Andersen had given up those four goals on 16 shots.
