The Capitals scored on their first shot, led 4-0 after eight minutes, and cruised to a 7-1 win against the Panthers on Thursday night, continuing their dominance over them at Verizon Center.
The Panthers have been outscored 23-4 in their past five visits to Washington, and they have lost nine of 10 trips to the nation's capital since the 2009-10 season.
Washington has won three in a row and five of six to climb the Southeast Division standings. Florida has lost four of five during a 3-6-4 slide that started with a 5-0 loss at Washington on Feb. 9.
Braden Holtby made 29 saves but lost his bid for a NHL-leading fourth shutout midway through the third period.
The first Capitals' shot of the game came from John Erskine, who cruised up to the blue line and launched the puck at goalie Jacob Markstrom. The Panthers' rookie opened his pads slightly, allowing the puck to sneak through 1:58 into the game.
It was 2-0 just 72 seconds later. From behind the goal line, Wojtek Wolski corralled a puck that deflected off the side of the net and snuck it in short side on Markstrom, who moved off the post anticipating a wraparound.
Markstrom was pulled without making a save, playing for the second time since being called back from San Antonio of the American Hockey League to replace Jose Theodore, out long-term with a groin injury.
Scott Clemmensen did not have any better luck, allowing Washington to take a 3-0 lead 2:28 after he entered. Capitals center Nicklas Backstrom won a faceoff to the point, and John Carlson beat Clemmensen stick-side on the fourth shot he faced.
It took the Capitals two more shots to make it 4-0. Matt Hendricks knocked the puck loose behind the net to Ovechkin, who, with his back to the play, fed a backhand pass to Ribeiro in the slot at 8:10.
It was the second-fastest four-goal start in Capitals history.
Washington made it 5-0 on the first shift of a five-minute power play created by an interference penalty to Florida's Tyson Strachan.
Ribeiro moved the puck off the right-wing boards to Troy Brouwer, whose straight-line pass found Ovechkin in the left circle, and his blast connected at 9:17. It was Ovechkin's ninth goal of the season, and he has 10 points in his past six games.
The collision between Strachan and Washington's Jason Chimera knocked Chimera from the game briefly. Strachan was given a major and a game misconduct.
Third-period goals by Eric Fehr and Mathieu Perrault sandwiched Skille's score for the final margin.
