Alex Ovechkin scored Washington's first goal of the game, cashing in on a power play in the first period. For the Caps captain, it was his 30th goal of the season, and the 12th straight season in which he has achieved that plateau.
Ovechkin becomes just the third player in NHL history to reel off a dozen straight seasons with 30 or more goals at the start of his career. He joins Hockey Hall of Famers Mike Gartner (15 straight seasons) and Wayne Gretzky (30 straight) on that short list.

"Congrats to O," says Caps coach Barry Trotz. "You think about it, some history was made tonight. You start your career and you get 30 goals a year for the first 12 years. You're one of three, you're in that elite company with Mike Gartner and a guy named - whatshisname - Wayne Gretzky. You guys might have heard of him, and then Alex Ovechkin. That's pretty good."
Ovechkin's goal also brought him to 400 career power-play points (209 goals, 191 assists). He becomes the 28th player in NHL history to amass as many as 400 points on the power play.
Winnie The Two, Part Deux, Déjà Two - Last October 15, the Caps started their 2016-17 home schedule with a Saturday night date against the New York Islanders. Washington earned a 2-1 victory in that game, the first win of what has turned out to be a record-setting season for the Capitals at Verizon Center.

Caps left wing Daniel Winnik supplied all of Washington's offense in that Oct. 15 game against the Islanders, the fifth time in his NHL career he had scored twice in a game.
Fast-forward to March 25, and the Capitals' last Saturday night home date of the 2016-17 season. Once again, Winnik struck twice, this time helping the Capitals to their 31st home ice victory of the season - a 4-1 triumph over the Arizona Coyotes -erasing a single-season franchise that was established more than three decades ago and matched just once since.

Winnik's goals also came against one of his half dozen former NHL employers; he started his career in the league with the Coyotes after Arizona expended a ninth-round draft choice (265th overall) on him in the 2004 NHL Entry Draft.
Winnik scored 11 goals as a rookie with the Coyotes in 2007-08, and he matched that figure with the Colorado Avalanche in 2010-11. On Saturday night against the Coyotes, he reached 11 for this season as well.
"It means a lot," says Winnik, of matching his single-season career high. "I hope to surpass that. I don't know how many games we have left [eight], but hopefully I do get past that. It's something I've tried for years. I don't think I can stress enough that I pray that it happens."

He has two more games remaining (one against Colorado and one against Arizona) against former employers this season, which can't hurt. Four of Winnik's 11 goals have come against his former teams.
Saturday's twin tallies bring Winnik's career total to 75 goals, and he now has three game-winners on the season, which is also a single-season career best.
Special Delivery - The Caps took an early lead on Ovechkin's power-play goal, and they were dealing with the extra man for the rest of the night, too. Washington had a whopping 21 shot attempts during the seven minutes of the game in which it had the man advantage, but only six of those shots ultimately got on goal.
During a double-minor to Arizona defenseman Connor Murphy in the second period, Washington kept the puck and the heat in the Coyotes end for nearly the entire four minutes. Arizona defensemen Luke Schenn and Oliver Ekman-Larsson were both on the ice for a shorthanded shift of 2:51 in duration during that kill.

The Caps were 1-for-4 on the power play for the night, and they were a perfect 4-for-4 on the penalty kill. Washington is 20-2-0 this season in games in which it scores at least one power-play goal and is perfect on the penalty kill.
Mister Consistent - Marcus Johansson notched a secondary assist on Ovechkin's power-play goal, pushing him to 48 points (22 goals, 26 assists) on the season. That's a single-season career best in points for Johansson, whose previous career high was 47 points, achieved in 2014-15.
A paragon of consistency during his seven seasons in the NHL, Johansson has recorded between 44 and 48 points in five of his seven seasons, with the only exceptions being his rookie campaign and the lockout abbreviated season of 2012-13.
The Puck Stops Here - Caps goalie Braden Holtby earned his 39th win of the season on Saturday, moving to within one victory of joining Martin Brodeur and Evgeni Nabokov as just the third netminder in league history to achieve three straight seasons of 40 or more victories.

Additionally, Holtby ran his home record to 26-6-2 on the season, establishing a Capitals franchise record for most wins by a goaltender on home ice. Olie Kolzig won 25 home games for the Caps in 1999-00 and Holtby matched that figure last season.
Down On The Farm - The AHL Hershey Bears took to the road this weekend for a pair of games in Newfoundland against the St. John's IceCaps. Hershey started the weekend off on a tough note, taking a 4-3 setback from the IceCaps on Saturday.
Hershey scored three times in the first period to take a 3-1 lead. Tyler Lewington netted his third goal of the season on a single assist from Jakub Vrana at 7:50 of the first, and Travis Boyd made it a 2-1 game less than a minute later when he scored for the 14th time this season. Christian Djoos and Mattias Backman assisted on the Boyd goal.
With exactly four minutes left in the first, the Bears made it 3-1 on Chris Bourque's 18th goal of the season, Chandler Stephenson and Madison Bowey assisting.
But that was as good as it would get for the Bears on this night. The IceCaps scored twice in the second to tie the game, and they administered the death blow on a Keegan Lowe goal with just 16 seconds remaining in regulation.
Pheonix Copley stopped 27 of 31 shots he faced in a losing effort in the Hershey nets. The two teams go at it again on Sunday in St. John's.
Down a level, the ECHL South Carolina Stingrays earned a 5-3 win over the Atlanta Gladiators on Saturday night at North Charleston Coliseum. Patrick Megannety, Joey Leach, Derek Arnold, Kelly Zajac and Joe Devin scored in support of Parker Milner's 18-save performance in the Stingrays' crease.
