David Pastrnak had his 11-game point streak snapped Monday night in Toronto, and Tuesday night the Ottawa Senators held him off the scoresheet as well.

It might be hypercritical to say that he’s hit a slump after just two games, but the Boston Bruins winger has had his troubles in both. Just about every time he’s tried to dangle defensemen, Pastrnak has lost the puck. He fanned on another one-timer attempt in the third period of the 3-2 loss to Ottawa.

Pastrnak has had a terrific third pro season, becoming a 30-goal, 30-assist player at the age of 20. But he did have a 17-game goal drought earlier in the season, with a seven-game pointless streak within that period in December.

The Bruins can ill afford another long skid.

“I don’t know if frustrated is the right word,” interim coach Bruce Cassidy said. “It looks like the puck’s not cooperating with him, and that happens to goalscorers. He’s just got to play through it. He did earlier this year. Clearly we don’t want it to be as extended as it was then. I don’t think it will be. He’s a more mature player and person, but he’ll have to find his way through it. Sometimes you have to score an ugly goal, get a greasy one to get out of those things.

“We’ll see how it plays out, but he’s got to keep pushing. We need him. We’re relying on him to score. He’s not the only one but we’re relying on him.”

Tuesday night, Pastrnak was tagged with three giveaways.

“I’ve got to be better and I’ve got to make more plays,” he said.

As with most skilled players, especially ones like Pastrnak who play with a certain abandon, he has found himself on the receiving end of some physical play. So far he’s responded with a few face washes after the play.

“It’s part of the game, you know?” he said. “The guys are going to hit. I just need to stick with it and not let it frustrate me.”

In his previous two games, Zdeno Chara – a plus-17 in the 17 games he has played under Cassidy – was taken off the ice by opponents who were very glad to see him in the penalty box.

One instance followed a fighting major for a bout against Zack Kassian in Edmonton (the Oilers scored a power-play goal with Chara in the box), and the other came on a third-period matching minor with Matt Martin of Toronto (no harm done).

Cassidy looks at police work as part of Chara’s job.

“I think in Edmonton we were looking to re-establish ourselves,” Cassidy said. “That’s fine. That’s a couple of big bodies. I think they mixed it up the last time they were in here. . . . (In Toronto,) Z might have been protecting his little brother (defense partner Brandon) Carlo.

“So we have no problem with that. You’ve got to look out for one another.”

WEDNESDAY’S GAME

MAPLE LEAFS 5, BLUE JACKETS 2: William Nylander and Leo Komarov each had a goal and an assist, and Toronto won at Columbus, Ohio.
