Tony DeAngelo saved special praise for rookie goaltender Pyotr Kochetkov after the Carolina Hurricanes defeated the Boston Bruins 5-2 on Wednesday.

Kochetkov was thrust into the spotlight for his playoff debut as the Hurricanes took a 2-0 lead in what is becoming a fiery series.

With Frederik Andersen already down, tempers boiled over as the Canes had to turn to Kochetkov after Antti Raanta was struck in the head by David Pastrnak's glove as he skated past.

The two teams traded words and big hits throughout, and defenseman DeAngelo made it clear where the Hurricanes stand with the Bruins in this series.

"We're not going to get pushed around, I guarantee you that," he said.

DeAngelo was glowing of Kochetkov's demeanour after the first-period change and his ability to keep it simple in a heated environment, making 30 saves.

"I think he's real calm," his team-mate said. "You don't see any jitters, at least in my eyes. I don't know what he's feeling inside. I'm sure he's a little nervous. Anybody would be, right?

"But I thought he was real calm in the net. He made a lot of saves, wasn't trying to do too much. He was calm. Coming into goal in the first period in a playoff game as a rookie after coming here a few weeks ago, he was really good."

Elsewhere on Wednesday, the Tampa Bay Lightning and the Minnesota Wild tied up their respective series against the Toronto Maple Leafs and the St. Louis Blues with wins.

The Edmonton Oilers also tied up their series, smashing the Los Angeles Kings in a 6-0 shutout.

The NHL's leading goal-scorer and MVP candidate Auston Matthews slotted home two more in the Toronto Maple Leafs' 5-0 win against the Tampa Bay Lightning in Game 1 of their playoff series.

Matthews – who is first player since 2011-12 to score 60 goals in a season – got on the scoresheet early in the second period to make it 2-0 for Toronto after Jake Muzzin's opener to close the first frame.

Mitchell Marner assisted the first Matthews goal and also set up David Kampf to make it 3-0, before he got on the scoresheet himself to make it four, capping off a brilliant second period.

Matthews scored his second goal of the game to round out the rout in the last period, with Morgan Reilly collecting his second assist in the process.

Speaking to post-game media, Matthews gave plenty of credit to the Maple Leafs' penalty-killing unit after the Lightning failed to score from five power-play attempts, as well as his running-mate Marner.

"I thought we played fast, we played through the contact," he said. "Our penalty-kill [unit] was huge tonight, I thought that brought us a lot of momentum.

"I thought [Marner] was incredible. He was all over the puck – so much poise – he's just doing his thing out there. 

"It's fun to watch, and fun to be out there with him. I know he's going to continue to elevate, so we've got to look for everybody to do that as well.

"We were able to capitalise on some chances, so I thought it was a really good effort by us. But it's a series – it's going to be a long series – and there's a really good team on the other end. 

"They'll be ready to go next game, so we've got to watch this one, learn from it, and move on to the next one."

Matthews also highlighted the energy inside the building as the Toronto crowd tries to will their team to their first series win since 2004.

"It was humming here tonight," he said. "It was just electric through all 60 minutes.

"I think that's what playoff hockey is all about, the atmosphere and everything. 

"It's been a while since we've been in front of our fans in front of a full arena in the playoffs, so there's a lot of excitement, and the guys fed off the energy."

It was a similarly dominant showing for the Carolina Hurricanes, as they beat the Boston Bruins 5-1 at home.

There were five individual goal-scorers for the Hurricanes as Seth Jarvis, Nino Niederreiter, Teuvo Teravainen, Vincent Trocheck and Andrei Svechnikov put in one each.

The St Louis Blues collected an important road win against the Minnesota Wild, scoring twice in the opening period on the way to a 4-0 result.

David Perron was the man of the hour for the Blues, capping off his hat-trick with the final goal of the game, while Torey Krug had three assists.

The most competitive game of the night was the Los Angeles Kings' trip to take on the Edmonton Oilers, escaping with a 4-3 road win.

After two action-packed periods the sides were tied at 3-3 going into the last, with a late Phillip Danault goal proving to be the difference.

Jared Bednar believes Taylor Hall's hit on Nathan MacKinnon is the type of challenge the NHL is looking to phase out.

The Colorado Avalanche had to play most of Wednesday's meeting with the Boston Bruins without five-time All-Star MacKinnon after Hall connected with his shoulder in the first period.

Hall's shot to the upper body resulted in MacKinnon's own stick snapping up into his face, causing bleeding from his nose as the Avs star lay on the ice.

MacKinnon left the ice and did not return, while Hall was given a five-minute major that was reduced to two minutes after a review.

Colorado went on to win 4-3 in overtime and sit top of the Central Division in the Western Conference with 30 victories this season, the highest total in the league.

Though coach Bednar thought the right decision had been made in regard to Hall's penalty, he claimed it is the type of dangerous hit that the league is hoping to force out of the game.

"I believe they probably made the right call with the two [minutes],'' Bednar told reporters.

"But it's the type of hit, whether it's really solid or just a glancing blow, it's the kind of hit the league is trying to get rid of.''

Bednar also confirmed that MacKinnon had come around after the blow and would be assessed ahead further on Thursday, with the Avalanche in action again on Friday against the Chicago Blackhawks.

The Avalanche, who led through Kurtis MacDermid early on, were down 3-1 in the third period before Samuel Girard pulled one back. Gabriel Landeskog tied the game with 36.5 seconds remaining before Cale Makar sealed the comeback win in overtime. 

"Not fun seeing one of your best friends and obviously your top player on the ice bleeding like that,'' added Landeskog.

"We didn't want to give up. We wanted to keep going. We got the big two points, keeping this thing going at home.''

The Avs have now won 17 games straight at home, just six behind the league record set by the 2011-12 Detroit Red Wings.

"That's our biggest win of the year," Bednar said.
