The Penguins were credited with the game's first goal 7:56 into the opening period. Nick Bjugstad, fresh off injured reserve, crashed the net and fell into Johansson at the top of the crease. As they both tumbled, Patric Hornqvist, also down on the ice, swept a backhand into the net. Buffalo challenged the play for goaltender interference, but lost the challenge and found themselves down a man as a result.
McCabe responded quickly, capitalizing on a neutral zone turnover and scoring top shelf on a shorthanded breakaway chance at the 9:01 mark of the first. It was his second career shorthanded tally. The other came on Jan. 8, 2019 against New Jersey.
Pittsburgh reclaimed the lead when Pettersson's shot from the point beat Johansson five hole with 7:34 to play in the first. Patrick Marleau had camped out all alone in front to set up a screen.
They went up 3-1 when Hornqvist added his second goal on the power play.
Johnasson accepted a great pass in the slot from Dominik Kahun to wrist in his ninth goal of the year 1:57 into the third to make it a one-goal affair.
But Crosby scored at the 6:02 mark of the final period to regain the two-goal edge.
