Phil Kessel and Jake Guentzel each had two goals and an assist, but Pittsburgh knew it wouldn't have been in the game if not for Fleury, who finished with 34 saves.
"He's been our best player," Penguins coach Mike Sullivan said. "In the first series (against the Columbus Blue Jackets), the first two games here, he's made timely saves for us, especially in that first period."

Capitals goaltender Braden Holtby was pulled after allowing three goals on 14 shots in the first two periods, and Philipp Grubauer made six saves in the third.
The Penguins were being outshot 19-5 before Matt Cullen beat Holtby between the pads on a shorthanded break to give the Penguins a 1-0 lead 1:15 into the second period. Matt Niskanen scored a power-play goal from the left circle at 2:09 of the second period to tie it 1-1.
Sidney Crosby assisted on goals by Kessel at 13:04 and Guentzel at 16:14 to make it 3-1. Crosby set up Kessel for a right-circle shot into the right corner, then blocked Justin Williams' shot from above the left circle and nudged the puck ahead to Guentzel, who raced down and beat Holtby to the short side from the right circle.
"The playoffs are made of big moments," Holtby said. "That third goal, that's a big moment. That's where your goalie needs to come up with a save and I just didn't."
Kessel scored a power-play goal from the left circle 2:19 into the third period to make it 4-1. Nicklas Backstrom knocked in an Alex Ovechkin rebound to pull the Capitals within 4-2 at 3:44, but Malkin put the Penguins up 5-2 with a deflection at 5:31.
Guentzel scored an empty-net goal with 43 seconds left to make it 6-2. He leads the Stanley Cup Playoffs with seven goals.

Goal of the game
After taking a pass from Guentzel in the neutral zone, Crosby put the puck between his legs as he crossed the Capitals blue line, drawing three defenders to him before dishing off to Kessel.
"He fought off a couple guys and obviously he's special like that," Kessel said. "He's real strong out there and he'll make a great play."

Save of the game
Tied 0-0, the Capitals were on the power play with 1:27 remaining in the first period. Andre Burakovsky made a strong move to the net from the right side and attempted to tuck the puck inside the far post. But Fleury stayed with Burakovsky as he cut across the front of the net and kicked out his right pad to make the save.
Highlight of the game
Cullen blocked Kevin Shattenkirk's point shot, then chased down the loose puck before fighting through Shattenkirk's hook to slip the puck between Holtby's pads.

Unsung performance of the game
The Penguins were leading 5-2 when defenseman Ron Hainsey stepped in front of a high left-circle shot from Ovechkin with the Capitals on the power play and 2:23 remaining in the third period. Hainsey turned his head at the last instant, was struck on the back of the helmet with the puck, and had to be helped off the ice.
