Puck over glass. The New York Rangers don’t score.
Puck over glass. ‘‘Casual Mike’’ does.
The NHL’s black-and-white delay-of-game rule found a gray area late in regulation, then tipped the balance of the game twice in overtime. The Washington Capitals held firm when they were a man down, then won it on Mike Green’s latest extra-time winner, topping the visiting Rangers, 1-0, Saturday to take a 2-0 series lead in the Eastern Conference playoffs.
It’s the eighth career overtime goal — and first in the postseason — for the defenseman whose more well-known nickname is ‘‘Game Over Green.’’
‘‘When it gets to overtime and guys start to get the shakes a little bit, he’s still calm Mike Green,’’ teammate Karl Alzner said. ‘‘So he’s able to find those goals. We call him ‘Casual Mike’ every now and then.’’
Braden Holtby made 24 saves for his first career playoff shutout for the Capitals and has stopped 59 of 60 shots in the series.
Game 3 is Monday in New York.
Green got his chance because the Capitals’ power play — the best in the NHL during the regular season — finally returned to the ice thanks to the rule that sends a player to the box when he ‘‘shoots or bats’’ the puck ‘‘directly’’ over the glass while in his defensive zone.
The Rangers had done a better job staying out of the box after taking too many minors in Game 1, but the officials had no choice when defenseman Ryan McDonagh clearly committed the error 7:09 into overtime.
‘‘Just got a little too under it,’’ McDonagh said.
On only their second man-advantage of the game — and first since the first period — Green nailed a one-timer from high in the slot on a feed from Mike Ribeiro precisely at the eight-minute mark of the extra period.
Contrast that with the New York power play that started 1:51 into overtime, after Steve Oleksy was whistled for the over-the-glass miscue. The Rangers failed to get a shot on goal during their two minutes of 5-on-4 — or at any point in the extra period.
Kings 1, Blues 0 — Jonathan Quick made 30 saves in his fifth career playoff shutout, leading host Los Angeles over St. Louis and trimming the Blues’ series lead to 2-1.
Slava Voynov scored in the second period for the defending Stanley Cup champions, who got a brilliant performance from their Conn Smythe Trophy-winning goalie in a tight game.
Los Angeles will attempt to even the series in Game 4 on Monday night.
After making self-described mistakes that led to both of the Blues’ winning goals in St. Louis, Quick won his duel with Brian Elliott, who stopped 20 shots.
Ducks 4, Red Wings 0 — Nick Bonino scored for visiting Anaheim on a second-period power play — 18 seconds after Detroit’s Justin Abdelkader was ejected for a violent hit on Toni Lydman — and the Ducks went on to a victory and a 2-1 series lead over the Red Wings in the Western Conference playoffs.
Lydman was playing the puck in the corner near his own net when Abdelkader sped over and flattened him with a high hit. Abdelkader appeared to catch Lydman square in the side of the head with his left shoulder, and he was given a major penalty for charging and a game misconduct with 4:49 remaining in the second.
The Ducks took advantage when Bonino backhanded a shot past Jimmy Howard from point-blank range.
Ryan Getzlaf, Emerson Etem, and Matt Beleskey scored in the third period for the Ducks.
