The Penguins and Capitals met in the second round of the playoffs the past three seasons. Pittsburgh knocked off Washington on its way to winning the Cup in 2016 and 2017 before the Capitals turned the tables last season and went on to win the Cup for the first time in their 43-season history.
They've played 19 playoff games against each other over the past three seasons, and there very well could be more coming at the end of this season.
"I don't think there's really any secrets out there between us two teams," Pittsburgh goaltender Matt Murray said. "We've seen them a whole lot, obviously, the last little bit. They're a great team obviously. They're one of the best teams in the League, for sure. I think we're a pretty good team as well."
The Penguins' offensive weaponry was on full display in the season opener. Letang had two goals and an assist, Jake Guentzel scored twice, Evgeni Malkin had a goal and an assist, and Crosby got two assists.
But as they did in the playoffs last season, the Penguins struggled at times defensively against the Capitals' speed and with handling the puck. Murray had a rough start, allowing three goals on the first four shots he faced.
Then when Pittsburgh appeared to have the game under control with a 6-4 lead in the third period, Malkin turned over the puck to T.J. Oshie, who scored with 6:59 remaining to pull Washington within one goal. Oshie scored again on a deflection 21 seconds later and the game was tied 6-6.
