DENVER — Nathan MacKinnon already had the Avalanche’s first four-goal game. He has points in each of the 24 home games. He even had a 19-game point streak and is currently riding a 12-game point streak. He accomplished all of these feats this season alone.

And now he has a natural hat trick — just the second one in franchise history. And the franchise’s second four-goal game, too.

MacKinnon scored three goals in the second period in a span of 6:37 and added another in the third, helping the Avs to a one-sided 6-2 triumph over the Washington Capitals on Wednesday.

The only other natural hat trick came from Joe Sakic in 2003.

“It’s always nice to score four, obviously, I’d be lying if I said anything different,” MacKinnon said.

Following a two-week hiatus from Ball Arena, MacKinnon continued what was already an impressive home point streak. His first tally extended his season-opening streak to 24 games — just one back of Bobby Orr for the second most in NHL history.

MacKinnon also reached 82 points, ending the night with two more points than Tampa Bay’s Nikita Kucherov for most in the league. The duo is 15 and 13 points up on the rest of the field, respectively.

MacKinnon also recorded an assist on a late third-period goal from linemate Mikko Rantanen, giving him five points following a four-point night four days earlier.

In his four-point effort on Saturday, he passed off his own hat trick to set up Logan O’Connor for his first career three-goal game on an empty net. O’Connor, a hard-working bottom-six forward, praised MacKinnon following Colorado’s 7-4 victory in Philadelphia over the weekend.

“It’s probably been fifteen years since my last hat-trick. Pretty unselfish play by Nate there,” O’Connor said on Saturday. “I think he knows he’s gonna get a lot more hat tricks than I will.”

It took just one game for MacKinnon to get another hat trick — his second of the season and sixth of his career. At some point, MacKinnon’s play would have to surprise his coach, right?

“Couldn’t. He couldn’t surprise me,” head coach Jared Bednar said. “I mean that’s just where he’s at.”

Rantanen also had five points, assisting on each of MacKinnon’s four goals. Superstar defenseman Cale Makar had two helpers and the game-opening shorthanded goal in the first period. Makar’s goal gave him 76 on his career, which passes Tyson Barrie for most in Avalanche history among defensemen.

Makar started the scoring with a great individual effort at 19:23 of the opening frame, wiring one past goalie Charlie Lindgren for his first career regular-season shorthanded goal.

At the other end, goalie Alexandar Georgiev recorded his league-leading 26th victory. Georgiev struggled at times during the road trip. But in his last outing at home, he made 25 saves to blank the Vegas Golden Knights. Against the Capitals, Georgiev stopped 23-of-25 shots. Colorado outshot the visitors, who had played the night before, 31-25.

“I loved his game tonight. I thought he was fantastic,” Bednar said of Georgiev. “He just looks square and sharp, less rebounds. Pretty aggressive, challenging.”

MacKinnon’s first two goals were scored in a similar fashion. Setting up from the circle to the right of Lindgren, MacKinnon used his lethal one-timer twice, on the power play, to increase the Avs’ lead. His first power-play tally was set up by Rantanen and the second came off a pass from Makar. In each instance, Lindgren pushed from left to right but couldn’t get to the puck in time.

“The puck movement was great,” MacKinnon said of the power play.

His third goal came on a two-on-one rush with MacKinnon on the counterattack. Rantanen found MacKinnon, who went from his forehand to backhand before beating Lindgren for the third time.

The Avs found themselves on a late 4-on-3 power play. And moments after it expired, MacKinnon received a pass in the slot and fired a wrist shot past Lindgren to reach four goals. He became the first player since Alex Ovechkin in 2007-08 to record multiple four-goal games in the same season.

“I’m not really surprised by the way he plays,” Rantanen said of MacKinnon. “Off the ice he’s really dialed in, being an athlete, hard work ethic.”
